How We Can Stop Hating Wasps

Recent studies have shown that wasps are among the most loathed of all insects. Consequently, much time and money is wasted on trying to eradicate them, especially by homeowners. Let’s consider why we have the attitudes we do, and how we can achieve coexistence with wasps.

A trio of Western Yellowjakcet workers dispatches a pest caterpillar.

Why do we hate wasps?

There are three main reasons wasps evoke fear and loathing.

• The sting. Females of some species can inflict painful stings on us tender humans. This is occasionally for self-defense, but mostly in defense of a nest full of immobile and otherwise vulnerable eggs, larvae, and pupae inside a nest. Only social wasps will bother us this way.
• Narrow definition of “wasp.” Most people equate the word “wasp” with “hornet,” “yellowjacket,” or “paper wasp.” All of these are social wasps, the ones most abundant in urban and suburban settings, and by far the ones we have the most negative encounters with. Some people recognize other kinds of wasps, particularly mud daubers, but consider their nests unsightly, a nuisance, or a potential threat. In reality, the overwhelming majority of wasps are solitary, like mud daubers, each female making her own nest, or using a host animal or plant in situ. Most wasps cannot sting people. Many cannot sting at all. Most are tiny, only ten millimeters or less in length.
• Social wasps exploit our habits and weaknesses. Yellowjackets (including the Bald-faced “Hornet,” and paper wasps make their nests in and around our homes and buildings. This is because our architecture mimics the cliff faces, rock overhangs, and natural hollows where they nest “in the wild.” A few yellowjacket species are scavengers, and your barbecue or picnic resembles an abandoned animal carcass that can be exploited. The wasps take protein matter back to the nest to feed their growing larval siblings. Meanwhile, your open soda or beer container offers sugary carbohydrates the adult wasps need to fuel their flight muscles. We like to think we are masters of our domain, or at least our private property, and wasps defy that desire with maddening efficiency.

Most wasps, like this "fairyfly," are tiny, solitary, and don't sting people.

Benefits of Tolerating Wasps

Positive outcomes from tolerating wasps, or even accommodating them, far outweigh any perceived benefits of eradication or control, excepting rare cases where you or another family member has hypersensitivity to insect venom, and there is demonstrable risk of a life-threatening incident.

• Saving money on products or services. This point is seldom made when arguing against the use of DIY pest control products, or the employment of professional pest control services, but it can be of profound financial consideration. Prevention is easier and more effective. More on that in a moment.
• Wasps are a pest control service. Most social wasps, even those that scavenge occasionally, are predatory on insects that are problematic in our yards, gardens, barns, and sheds. Solitary wasps are parasitoids of even more species that can be truly pestiferous. Among the hosts for wasps are caterpillars that eat garden plants, aphids that suck plant sap, flies that can potentially spread bacteria, cockroaches both outdoors and indoors, and spiders. There is scarcely any terrestrial arthropod that is not host to at least one wasp species.
• Wasps are pollinators. Technically, most wasps are “flower visitors,” coming to blossoms for nectar to fuel their flight muscles. They still effect pollination services, and there are some species in western North America that are obligate pollinators of certain wildflowers.
• Wasps dispose of animal carcasses. Those scavenging yellowjackets make quick work of the remains of small animal carcasses that vultures and other vertebrate scavengers ignore or cannot find. This prevents the accumulation of decaying animal matter, lessens risks to human health from problematic bacteria, and prevents explosions of filth flies that would otherwise use those dead animal resources.
• Wasps are a source of fascination and intrigue. Wasps can be easily and safely observed as they go about their activities of host-seeking, flower-visiting, and nest-making. You will be surprised by how many wasp species are living in obscurity in your yard and garden. Watching them will reveal amazing relationships with many other organisms.

Paper wasp nests can be safely observed and offer hours of fascination.

How do we get along?

We can prevent most negative encounters with wasps by taking a few precautions. It will literally save you physical pain and financial discomfort.

• Learn wasp body language. Paper wasps, the ones that make uncovered paper combs under eaves, in door and window frames, and elsewhere, are usually amicable neighbors. If you do approach a nest too closely, one or more wasps will stand on tiptoe and flare their wings. This means “back off.” You risk being stung if you ignore that warning.
• Inspect your yard regularly. Too often, underground yellowjacket nests, or those above ground, hidden in shrubs or rock walls, are not discovered until the lawnmower runs over one, or the hedge trimmer triggers an attack. Inspect your property thoroughly, including playground equipment, before using tools, or otherwise causing any strong vibration in the vicinity of a social wasp nest. It may take a little patience and keen observation to note the streams of wasps coming and going regularly from a specific location. Your kids may see them before you do.
• Serve beverages outdoors in clear glass or plastic.
Unattended beverages that are sweet or fermented will attract yellowjackets and other wasps that may crawl inside the container. Cans and opaque bottles mean that you will not notice a wasp inside. A sting to the tongue or throat can be a life-threatening experience regardless of whether you are allergic to stings.
• Cover food served outdoors. When not serving yourself or others, cover meats and sweets at the outdoor gathering. You can also set out a small, exposed plate of meat a good distance away from the serving table, to draw yellowjackets away.
• Seal cracks and crevices. To prevent wasps from nesting indoors, or seeking shelter in the winter, seal cracks and crevices. Mend holes in, or replace, window screens. Screen the attic vent with fine mesh. Replace worn weatherstripping around doors. This will help save on heating and cooling costs, too.
• Learn to recognize solitary wasps. Many wasps that are solitary may behave as if they are social. A large number of wasps flying low over your lawn are likely male wasps looking for females that have yet to emerge from the ground. An ominous gathering of iridescent blue mud daubers in a door frame at dusk means that males are bedding down for the night in a large group. Male wasps do not sting. Cicada killers are huge wasps, but solitary. Females may nest close together, making them appear social. Males keep watch over them and may fly “aggressively” to chase away any and all intruders. It is all bluff.

Home Bioblitz, Ongoing

Ever since we moved into our house in Leavenworth, Kansas, USA, in mid-May of this year, we have been keeping a tally of all the species of animal life we see on our property, or from it in the case of flying birds. As of August 12, we have surpassed seven hundred (700) taxa, and that is likely conservative.

Rove beetles, like this one I have yet to identify, have been a dominant taxon (family Staphylinidae) in our home landscape

A taxon is any level of taxonomic classification: Domain to Kingdom, Phylum, Order, Family, Genus, or species, and various divisions in between. It is often impossible to distinguish various species, or even genera or subfamilies, from images of the living creature in the “wild,” so many of the insects and arachnids we have observed may never be identified specifically.

Leafhoppers abound in diversity, too, including Idiodonus kennicotti....

....and Colladonus clitellarius, the Saddled Leafhopper

A bioblitz is typically a twenty-four-hour event at a specific location that is intended to inventory every kind of living organism within the boundaries of said property. More recently, bioblitzes have been conducted over two days, sometimes more, to enhance the experience of participants and get a more thorough survey accomplished. Sometimes, bioblitzes target one particular taxon of interest, like dragonflies and damselflies, for example.

No water feature in our yard, but still we get visits from odonates like Skimming Bluet, Enallagma geminatum

The website and smartphone app iNaturalist has become a handy platform for recording the results of bioblitzes, such as this one at Corral Bluffs Open Space, a new park near Colorado Springs, Colorado, internationally famous for the discovery of several new fossil species, especially early mammals. Making such data and observations widely accessible to the public, as well as to scholars, is an overriding priority for bioblitzes, and it inspires more bioblitzes.

Ants, like this Temnothorax sp., are always abundant, but more diverse than you think

I have been slowly uploading observations of wildlife at our home, and elsewhere we have traveled, to iNaturalist, but I am over one month behind.

Insects are always making more of themselves, like these Black-backed Grass Skimmer flower flies, Paragus haemorrhous

Our property is modest, with a front and back yard, a back porch and a side porch, and a detached garage. We have not yet planted anything new, save for a handful of daisies and coneflowers from a local nursery. We do mow what passes for the lawn, and intend to replace most of it eventually with native plants, and maybe add a small water feature and bird feeders. The front yard is dominated by an enormous red oak.

Daisy Fleabane, a "weed" that volunteered in the back yard, has a long bloom cycle, attracting insects like this Wavy Mucksucker flower fly, Orthonevra nitida

How have we amassed so many species in so little time? We are privileged to have the luxury of unlimited free time at present. Heidi spends most mornings looking and listening for birds in both yards, and beyond. The pigeons are usually flying over the federal penitentiary located two blocks behind us. A pair of Eastern Wood-pewees raised a family in a tree across the street from our front yard. I make a circuit around the yards at least once per day, usually.

We have lots of spiders, and Blue Mud Daubers like this one hunting them

We have not yet tried much in the way of trapping for insects. We did hang up a bee block under the eave by the living room window, but apparently weren’t watching it at the right time of day. About a week ago I noticed two of the holes had been plugged with mud, likely the work of a mason wasp. We occasionally set out overripe fruits, but those are quickly overrun with ants unless we take precautions like standing a section of log like a pedestal in a container of water that acts like a moat.

We have fireslies that flash, like this Big Dipper Firefly, Photinus pyralis!

We do blacklight fairly regularly, though at present my camera flash has ceased to work. My back-up cameras have repeated lens error issues whereby the extendable lens gets stuck. Finding another camera has been problematic as there are shortages of almost every item now due to the pandemic. That said, blacklighting has been the overwhelming source of our diversity. I frequently find “bonus” insects in images where the intended subject was something else entirely.

Blacklighting has brought us gems like this Black-dotted Glyph, Maliattha synochitis

Here is my challenge to you: although we are no longer confined to our homes by the novel coronavirus, consider staying put anyway and devoting time to bioblitz your own place. Even the most sterile apartment is likely to have a few dozen species. You might have to break out a magnifying lens, but they are there. Share your results on iNaturalist, Project Noah, or similar platforms. Ask for help if you are at a loss for ideas on how to get started. Happy hunting!

Our (New) House

My wife, Heidi, and I moved into our new home in Leavenworth, Kansas on May 17. Our house is a very, very, very modest house, with a front yard and a back yard, and a detached garage. It will take some getting used to, as our former townhouse in Colorado Springs had little outdoor space we could truly call our own, and it was maintained by a homeowners’ association (HOA). We have not yet met our human neighbors, but have become acquainted with the wildlife.

While we are still cramped by unpacked boxes here and there, it has been the weather that has been most frustrating and depressing. Colorado Springs boasts over three hundred days of sunshine per year. Here, in a little more than two weeks, we have had two full days of sun. Otherwise, it has been overcast, dreary, often raining, and unseasonably cool. Yesterday it barely made it over 60° F. Heidi insists it is warm and humid, I say it is cool and damp. On the days when it has been dry, my allergies to grasses and spring trees have made my mood just as miserable as the cloudy and wet days.

Back yard, before mowing. The federal penitentiary is visible behind us, and brightly illuminated at night.

Despite the inclement weather, we have been exploring our property and keeping a list of the animals we find. While unloading the U-haul, Heidi tallied thirteen species of birds. I turn the porch light on at night, and on two occasions deployed a blacklight, and many insects have revealed themselves. Our accounting now numbers over 190 taxa (anything from phylum to species, depending on our familiarity with a given organism).

Tiny, adorable weevil, Lechriops oculatus, on the back fence.

So far, our home seems to be spider city and weevil central. We appear to have a resident Eastern Gray Squirrel inhabiting the huge oak tree in the front yard; and American Robin and Mourning Dove often bask on the wires over the garage and back yard. Reluctantly, we mowed what passes for our lawns, but kept the cutting level as high as we could, leaving the herbaceous vegetation along the fence line in the back as intact as possible. We have Ground Ivy, clover, dandelion, and even some violets growing among the grass and leaf litter.

Leavenworth is a rather quaint town, the residential neighborhoods being almost literally the All-American communities one thinks of in the “fly-over” states, but no one has been overly welcoming, let alone ringing the doorbell with pies and other foods in hand. I imagine that the continuing pandemic has something to do with the abortion of traditional greetings and offerings, but I also suspect a growing pall of suspicion and distrust that has always been there, but is now pervasive and….normal. Is everyone on the block talking about us on the Nextdoor app, speculating about why I am prowling around with a camera, and stretching a sheet and a UV light off the front porch?

Small, horned darkling beetle, Neomida bicornis, drawn to the front porch light at night.

Driving around in the course of picking up items for our household, and running errands to establish our residency in the civic sense, it is apparent that the cities of Leavenworth and Lansing, and the county of Leavenworth, have a good deal of untamed greenspace among the agricultural fields and commercial enterprise districts. It will be interesting to explore, provided the weather improves.

I was telling a friend back in Colorado Springs, one of the few people we saw immediately before we left, that I feel cheated by the pandemic year. I had an entire twelve months where I saw almost no one outside of my spouse, and now I am being swept away without having much in the way of meaningful parting encounters.

Here I am now, knowing no one but my in-laws, and having met a couple of Heidi’s high school classmates briefly, two years ago. Being a sudden stranger is hard, folks. I am likely to retreat to the comfort and familiarity of the insect world where I actually recognize some old friends.

UPDATE: Concerning my health, my respiratory issues have almost completely resolved themselves. The cause was apparently a severe allergy I developed to our pet bird, a budgerigar (“budgie”). My wife’s parents visited us in Colorado about three weeks before we moved, and we sent the bird away with them. My symptoms of coughing, wheezing, and shortness of breath vanished almost immediately. I will sincerely miss the sweet tweeting of our “boy named Sue,” but am grateful to be sleeping soundly, in our bed instead of a chair, with no need of an inhaler.

Beat The Winter Blues With An Indoor Bug Hunt

Are you tired of waiting for spring to bloom? Snowed in for yet another weekend? You can find a surprising number of creatures without leaving the comfort of your home. Just how comfortable you will be after your indoor discoveries is another question, but most of your home's biodiversity will be benign.

The variety of insects in one light fixture:dark-winged fungus gnats, carpet beetles, a weevil, aphids, thrips, gall midges....

Before you begin your indoor expedition, you might want to read Rob Dunn's Never Home Alone. The book is an excellent primer for a home bioblitz (inventory of a given taxon of organisms in a short period of time). It can give you a good idea of what to expect, and calm any potential fears. Indeed, the thesis of Never Home Alone is that the more biodiversity in your household, the better. At the end of the day you will be discarding pest control products and harsh cleaning agents....or buying more.

Web of a funnel web weaver spider in kitchen ceiling corner

Instead of being embarrassed by the cobweb in the corner, recognize the industrious nature of its maker. Compliment yourself for preserving a living pest control agent. See if you can find evidence of the insect victims the spider has trapped. Examine any shed exoskeletons to help you identify the spider itself if the living arachnid is not present. Dusty webs, unable to snare prey any longer, can be safely cleaned. Spiders will change "web sites" if they go long periods without success.

Indian Meal Moth, Plodia interpunctella

Don't forget to check your pantry. You may need a snack midway through your hunt anyway, but flour, rice, and other grains may hold unexpected insect surprises. Drugstore Beetles, Cigarette Beetles, Meal Moths, and spider beetles may be feasting on neglected stored products of vegetable origin. Dry animal-based foods can attract the Larder Beetle and carpet beetles, all members of the family Dermestidae. The wool garments in your wardrobe, and wool blankets, furs (but you have faux furs, no?), and silks are vulnerable to clothes moths and carpet beetle larvae, too. Try storing them in a cedar chest when you are not using them regularly. Cedar has proven repellent qualities and is not toxic to people or pets.

I spy some insects in there....

One of the most rewarding sources of insect diversity is a light fixture. The other day, one of our bulbs burned out and it gave me an excuse to see what insects had found their way into our home over the past several months. In our case, because we actively blacklight for moths in the backyard, we inevitably carry other tiny insects back inside after the night is over, so we might have a greater diversity of fauna than average, but probably not.

Dark-winged fungus gnats are often abundant indoors

You may not want to wait for a light bulb to expire before you examine a ceiling fixture or lamp, though. These days, the lifespan of the new generation of electrical bulbs is ridiculously long. It can be years before you have to install a new one. Further, insect specimens quickly die in the hot, dry conditions, become brittle, are eaten by carpet beetle larvae, and gather dust that makes them difficult to identify later. Best to check the lights often.

A lace bug in the light fixture?! Yep.

Last, but certainly not least, you will want to inspect for bed bugs. Adult bed bugs are small, no larger than the average apple seed. Immature stages are smaller still, some nearly transparent. You will likely see other signs of bed bugs before encountering the insects themselves, though. Should you find some, resist the temptation to blame your spouse, roommate, visiting guest, or tenants of the nextdoor apartment. Some authorities believe that one out of every four U.S. residences has bed bugs or will have them. Cimex lectularius thankfully poses no health threats that modern science is aware of. The biggest problems still stem from litigation over infestations, and the costs of eradication in a given dwelling.

Adult Bed Bug

Our home list of domiciliary creatures, including people and pets present and past, is approximately forty (40), over the last seven years or so. Clearly, we have more work to do. We do take comfort in the notion that we are providing homes for a broad spectrum of creatures, the great majority of which enhance our lives rather than detract from them.

Don't Try This (Pest Control Method) At Home

The news is replete with stories of people who have accidentally destroyed their homes, workplaces, and other structures in an attempt to kill a spider or insect. These are the sensational and drastic results of misguided intent, but there are many other negative consequences possible from do-it-yourself pest control. Do not be a sucker, a law-breaker, or the next headline.

A Word About Spiders

At this time of year, spiders venturing indoors is a top complaint of many homeowners. Please understand that if you notice a spider in your home or office it is an indication of....absolutely nothing. It is not out to get you. It is not a sign of an "infestation." It is not a sign that there are more to come. Male spiders of all kinds are on the prowl for females, and even those species that normally spin webs abandon them to look for mates, mostly in autumn. There are also plenty of spiders that never spin webs, like wolf spiders, jumping spiders, and longlegged sac spiders. Both males and females traverse large areas in search of prey. Occasionally, they will find their way indoors. Simply coax one of these spiders into a container and escort it outside to a log, stone wall, brush pile, or other place it can easily find cover. Thank you.

Foggers

Foggers are also known as "bug bombs," and can live up to that name if you fail to follow the deployment instructions to the letter. Forgetting to extinguish a pilot light on the water heater or furnace before detonating a fogger can result in burning your home to the ground, or blowing it to bricks and splinters. Moreover, as with any general insecticide, you are killing beneficial insects, and spiders and other arachnids, along with whatever pest you were targeting. Yes, those cobweb weavers in the corner are already controlling pests like carpet beetles and fungus gnats, and other household nuisances.

Read the Instructions!

Use a DIY product if you must, but be aware that improper application of that product is a violation of federal law. That is correct: You are subject to prosecution for misusing pest control products and devices. Yes, we do have to make a federal case out of it because the consequences of your ignorance can be far-reaching. This is especially true of lawn and garden chemical treatments. There is a reason that commercial landscape services are required to post those flags and signs after they poison, err, "treat" your lawn.

One of the most common mistakes with over-the-counter products is the assumption that using a greater quantity than prescribed in the label instructions will be more effective. The "more is better" philosophy can compromise the health of yourself, your family members, guests, and pets. Furthermore, some people may be hypersensitive to chemicals in the product, even if they are "inert" ingredients and not active compounds.

Don't Fall for "Harmless" Alternative Products

Say you do have the best interest of the environment at heart. You want the most benign, but still effective, "green" alternative. Good for you, but tune your scam senses to high alert, then. Among the most popular and well-advertised devices are those ultrasonic repellent thingies. They have been scientifically proven time and time again to be essentially worthless. Do not fall for it.

Consult the Proper Authorities

"Bug Eric" is not an expert on pest control. When in doubt, ask unbiased professionals about pest control products and strategies. Look for resources and agencies that do not have an agenda and are unaffiliated with either industry or non-profit organizations. The Environmental Protection Agency has a web page on the Do's and Don'ts of Pest Control that is a good place to start. Use your local branch of the Cooperative Extension Service for recommendations specific to your geographic location. The National Pesticide Information Center, headquartered at Oregon State University, is a wealth of factual information and additional resources. Subscribe to Consumer Reports magazine, a product of an independent product-testing institution that enjoys a stellar reputation in matters of consumer awareness and public safety.

Did I Mention Prevention?

It bears repeating that taking measures to prevent pests from gaining a foothold indoors or on your property, is the best solution. I will continue to post on this subject, but you can do your own research, too. Remember your neighborhood librarian is your best friend, and your library a wealth of information now networked with other public libraries, university libraries, and other resources around the world. Maybe you will begin with books like Tiny Game Hunting or The Humane Gardener.

Be In It For The Long Haul

Above all, understand that pest control never ends. There is no permanent solution. As the authors of Tiny Game Hunting write, "Thinking we can get rid of our pests permanently in one fell swoop is like taking a shower and believing we will be clean for the rest of our lives." Patience, persistence, and vigilance is necessary to keep the upper hand. Altering your mindset, your level of tolerance, and understanding of your insect and arachnid "enemies" is also key. We may need an attitude adjustment before we do anything else.

No Exterminator Necessary

Modified from © Pests.org

If this blog is successful at achieving only one thing, let it be a widespread understanding that you almost never need a pest control service. Here is your one stop post for how to tell if you need a service, and what you can do instead.

Just Passing Through

Every household, business, and workplace will have the occasional insect or spider visiting. Arthropods are masters at finding their way through the tiniest crack, crevice, hole, or other access point, which they hope will lead them to greener pastures, not indoors. They are not out to get you and they are not a sign that you are in for more creatures like them. It is usually a one-time event. Do not panic and dial up an exterminator.

One recent scientific study found that the average home is occupied, at one point in time or another, by somewhere between 30 and 200 species of insects, arachnids, and related arthropods. Still no reason for fear. In fact, the greater the biodiversity the better. It is a sign that your home is not sterile, but running on all natural cylinders. Most insects are so small you do not even notice them anyway.

The Pest Control "Racket"

While most pest control enterprises are ethical and fair, here are some points to consider:

• The technicians that visit your location are usually not entomologists trained to properly identify pests. They are schooled almost exclusively in proper application of insecticides to insure compliance with state and federal regulations.
• It is in the best interest of a pest control company to identify as a pest any insect that concerns you, regardless of whether it is a pest.
• Most pest control companies require a contract that guarantees repeated visits to your premises. Think about that. We expect plumbers and electricians to do the job right the first time.
• When was the last time a "product" or "service" solved anything? In the case of pest species the answer is almost never. The best solution is prevention and attitude adjustment.

You DO Need a Service When....

There are some situations in which you do need professional help. Those are:

• Bed Bugs are challenging for professionals, let alone do-it-yourselfers, and you will need to find a reputable company to deal with them.
• Structural pests like termites and carpenter ants. Make sure, however, that you are not mistaking an outdoor swarm event for an indoor infestation. A termite inspection is usually a requirement for home sale and purchase. Find an unbiased agent to conduct that inspection. Request an inspection if you suspect a termite or carpenter ant infestation before employing a pest control company.
• Social bee or wasp nest in a troublesome location. Always employ a bee removal service if you find a nest in a location that impedes your day-to-day life. Otherwise, note the location of the nest so you can simply avoid it. In most regions of North America, nests of yellowjackets, paper wasps, and the European Hornet are not perpetual, nor re-used the following year. Feral honey bee hives are perennial.
• Cockroach infestations that have reached extreme population levels. It is important to note that cockroaches have only been implicated in transmission of bacteria, never proven. Prolonged exposure to dense populations of cockroaches, their shed exoskeletons and feces may trigger allergies and asthma in some people, especially children in multi-family dwellings. Insist on a pest control service that uses baits rather than sprays for a longer-lasting, near permanent effect instead of repeated visits to spray insecticides.

The Cure is Prevention

Here are some ways to reduce the potential for pest problems in your home:

• Repair worn weatherstripping on doors and repair holes in window screens (or replace them).
• Seal all cracks and crevices, including around places where pipes and electrical conduits enter or leave the home. Pack steel wool into such situations, use caulking elsewhere.
• Inspect all objects coming indoors from outside, especially plants, firewood, toys, gardening tools....Inspect new plants before you leave the nursery or store.
• Do not reach your extremities into locations you cannot see into. Be careful moving items out of long-term storage to avoid spider bites, disturbing a wasp or bee nest, etc.
• Do not leave clothing, gloves, or footwear outdoors overnight, nor in the garage or shed. It never hurts to shake out shoes and clothes anyway.
• Reduce outdoor lighting or employ motion-sensors or bulbs that are less attractive to nocturnal insects. This will also discourage spiders from stringing their webs across your front and back doors.
• Never stack firewood against the side of your home, as this will help termites and carpenter ants to become established. Reconsider wood mulch as groundcover.
• Learn tips for how to avoid bed bugs in your travels and thrift store shopping. Entomologists estimate that soon one out of every four homes will have bed bugs.

Treatment for You!

Nobody wants to hear the suggestion that maybe they are the source of a problem, but sometimes that can be the case. Please seek professional help if you have phobias of insects (entomophobia), spiders (arachnophobia), or related creatures. It will save you a great deal of money and emotional turmoil to go that route. Otherwise, visit an entomologist for a gentle "attitude adjustment." We can cite example after example of the beneficial qualities of insects and the potentially disastrous effects of continued addiction to chemical pest treatments.

Please feel free to share this post widely. I also welcome comments, even dissenting opinions, as long as they are worded in polite language. Everyone deserves to make a living, and we will always need pest control services for situations where every other alternative has been exhausted.

"Product" is NOT the Answer to Every "Problem"

While I prefer to continue winning people over with compelling, fascinating stories of insect life and diversity, I would be remiss if I did not periodically issue posts aimed directly at changing human behavior in ways that will benefit them personally and other organisms as well. Thank you for indulging me in this exercise today.

Through my volunteer efforts and associations with AllExperts.com, Facebook groups, and even this blog, I am frequently asked questions that begin with "How do I get rid of...?" The automatic assumption is that an insect or spider in the house, workplace, yard, or garden must have an inherently bad disposition, or negative effect on people, pets, or property. This is the mindset that needs changing.

Let me give these individuals some credit for asking at least. The people who never ask at all, who literally spray first and ask questions later, are the ones we should really worry about. First of all, they will never know what kind of creature they are dealing with, and whether the product they are using will even have the desired outcome. Secondly, they inevitably do not follow the application instructions and risk poisoning themselves, another member of the family, a pet, and/or unintended targets in the form of beneficial invertebrates; they could even blow their house to splinters and bricks. They don't call them bug bombs for nothing. Never mind that failure to adhere to application instructions is a violation of federal and/or state law.

The real crime, however, is that we are incessantly conditioned that "product" is the answer to every problem (even when there is NO problem), and we are paying for it in so many ways, not the least of which are the side effects of chemical dependency in the agricultural and gardening sense.

Here is what no one is going to tell you. The nursery and landscaping industries have sold us on the idea that we can plant whatever trees, shrubs, and flowers we like, wherever we live, with no negative consequences. This is proven to be not only false, but an enormous ecological catastrophe when you understand the effects of exotic botanicals run amok (invasive species), and the chemical dependency required to prop them up in inappropriate soils, climatic zones, and exposure to local animal life. Further, imported plants invariably bring with them exotic insect and other invertebrate pests that themselves wreak havoc on native plants and ecosystems. So begins the "pesticide treadmill" first articulated by entomologist Dr. Robert van den Bosch in the 1970s.

Without fertilizers, herbicides, insecticides, and other treatments, most ornamental plants cannot survive outside their native lands. Native plants do not need this kind of intensive care, are vastly better at supporting beneficial insects, birds, and other wildlife we actually like to see, and their use in landscaping helps mend the holes in fragmented habitat that comes with suburban sprawl. Even in dense, urban areas, native vegetation can draw a shocking diversity of insect life normally relegated to what we would consider "wilderness."

We also greatly underestimate the ability of native plants to withstand nearly complete defoliation and bounce back just fine the next year. This is especially true of trees. A defoliated tree or shrub is not by definition "dead." The resiliency of flora in the face of natural agents of destruction is amazing. Meanwhile, the chemicals we dump on plants to "help" them? Not so good.

I cannot take credit for articulating all of this. Professor Doug Tallamy, in his landmark book Bringing Nature Home, outlines this dilemma eloquently. He also has the scientific studies and statistics to back up his claims. Besides the book, he also speaks to this idea wherever and whenever he is asked. Please check out this Youtube video for an example.

Making responsible choices in the marketplace and adjusting the attitudes within one's own mind are the keys to turning the planet's health around.

The same applies indoors. We panic and reach for the can of insecticide before we ask whether this one individual "bug" represents an actual pest problem or is merely an incidental, accidental visitor. We fail to repair the worn weatherstripping around doors, mend the holes in the windowscreen, inspect incoming objects from outdoors, and otherwise take simple preventative measures to exclude insects and arachnids in the first place.

If there is ever one post on this blog that I would ask you to share, it is this one. Please help spread the word that people can save money, time, and anxiety by simply being more curious, tolerant, willing to learn, and having faith in the way nature works without intervention. I will end with the remark that I have seen minds change, so I know it is possible. Stay tuned for those stories.

How to Respond to an Identification Request Online

Last week I posted a "how to" article on making identification requests online. I think it is only fair to suggest how to appropriately respond to identification requests. There is much needless redundancy on threads aimed at helping someone identify a given organism. Here are some ways to avoid that, as well as saving yourself time, embarrassment and/or criticism. Actually, the best default option is often to not respond at all. So, let's start there:

Do not respond to an identification request unless....

• You know what you are talking about. There are plenty of knowledgeable amateur naturalists, Master Naturalists, and citizen scientists, as well as professional scientists, online who can help make identifications. If you do not consider yourself in one of those categories, it may be best to refrain from commenting. That way, there is no need for someone else to correct you down the line. That said, you can be a professional and still be incorrect, but at least you'll be in the ballpark.
• You have read all of the previous comments! Most redundancy in threads comes from people eager to comment who do not realize the correct answer has already been given. Facebook does not make that easy, because a long thread leads to hidden comments and generates a header that reads something like "view previous [insert random number here] comments."
• You have something truly worthwhile to add to the conversation. Anecdotal observations can be genuinely helpful, and also create a sense of community in an online group. Post away. Comments like "Burn it with fire!" or "Eew, gross!" only reveal ignorance and intolerance. Use good judgment, and understand when to deploy a filter for your "hostile voice."

Ok, what else can we do, or not do, to make an identification request more efficient and productive? Here are some ideas....

• Do *not* post another image *within* an existing thread. The addition of more images within a thread, unless the images are of the same specimen, by the same person who started the thread, creates great confusion. The internet as a whole is not always the best source of anything, let alone correctly-labeled images, even if the Google search results say so. If you want to post your own images, start a new thread.
• Include links to resources that back up your answer. There is no such thing as too much information, and most people asking for the identification of an organism know nothing about it. So, providing a link that sheds light on the life cycle, biology, and ecology of the creature is usually received warmly.
• Learn who the other players are. If you doubt the credentials of someone else making comments, look them up and see whether your (low) opinion has any basis in fact. You might find that the person is a college professor, curator at a museum, author of a book, or otherwise has vast knowledge of the subject at hand.
• Do NOT argue with others. This is why I just suggested you get to know the other players, and find out who you can trust. Word your different opinion gently ("I think it is this rather than that, because of this characteristic, behavior, etc"). That way you are being respectful, and giving more insight, too.

I may or may not have covered everything here, so please comment with your own suggestions, including what I should have omitted. I may well revise this post accordingly.

The Myth of "Good Bugs" and "Bad Bugs"

Almost every insect identification request I receive includes the same question: "Is this a good bug or a bad bug?" Ok, another frequent question is "How do I get rid of it (them)?" The concept that any particular species of any organism is inherently good or bad is a symptom of collective ignorance, and I am not sure that the entomological community has done much to counteract that logic.

Caterpillars of the Cloudless Sulphur eat Senna. Can you live with that?

A good deal of our opinions and beliefs have been biased by large scale agriculture, and the fear-mongering media coverage of economic pests. You also have "organic" advocates who promote "beneficial" species, which they often have for sale in their nurseries and other businesses. The common denominator in those instances is money. Millions, if not billions, of dollars are at stake in products ranging from household and garden pesticides to bug zappers to laboratory-reared lacewings and parasitic wasps. Don't you know that you can't live without any of this stuff?

Get behind the sales pitch and the reality is much more subtle and variable. Take the praying mantis, for example. Here in the U.S. you can purchase the egg cases (ootheca) of the European Mantis, Mantis religiosa, for your garden, despite the fact that in most areas of the country you already have one if not several native species already there.

A native mantis eats a Queen butterfly

Then there is the idea that mantids are beneficial predators. Mantids are completely indiscriminate hunters. They will eat bees and butterflies as often as grasshoppers and caterpillars. There are even well-documented incidents of larger species killing hummingbirds. Mantids still looking wonderful to you now?

Phytophagous (plant-eating) insects, on the other hand, simply must be pests, right? If so, then how come so many species have been imported from overseas to control noxious weeds? Most herbivorous insects are highly "host specific," meaning they feed on only a few, closely-related plants. Those plants have learned to co-exist with the insects that eat them. The plants produce their own chemical defenses, and even "talk" to other nearby plants to warn them of an impending infestation. Native plants are better able to withstand an onslaught because they are growing in suitable soil and climate. This also allows them to quickly recover from even the most intense defoliation.

This leaf beetle was imported to control saltcedar (Tamarix spp.)

You can also not equate your garden, yard, or woodlot to a massive farm, orchard, or forest. The reason there are pests at all is because we insist on growing large scale monocultures of various crops (and I would include tree farms in that). What self-respecting European Corn Borer is going to turn up its nose (antennae?) at acres and acres of its host plant? We set the table and then complain about our uninvited guests.

The real world of nature does not play favorites, and if you want a healthy planet Earth, let alone a garden, yard, or home, then you have to stop thinking of every species as "good" or "bad." You don't have to like every creature. Personally, I don't like mantids, but I do recognize their place in the grand scheme of things, and appreciate their existence for that reason alone.

I heartily encourage a public attitude that embraces all life forms, treats them with respect, and actively cultivates a sustainable human culture in which we can all coexist....SLAP! Sorry, there was this mosquito....

Women and Bugs

The majority of questions that I receive at AllExperts.com are, perhaps surprisingly, from women. Even more encouraging, the questions are usually intelligent and do not give the impression that the person is panic-stricken. Why do women ask the questions? I have a theory, and it doesn’t have much to do with men not wanting to stop and ask for directions.

Women in American society, at least, are also on the front lines of the household and the workplace. They are the first to notice insects and spiders trespassing in the home or office. Their protective motherly instincts kick in, and their first priority is to determine the identity of the intruder and understand whether it poses a health threat to their family, co-workers, pets, houseplants, pantry, or property. They want to know, ideally, if there is a way to confront the creature that avoids using insecticides or other toxins. A few are truly concerned about acting humanely toward the organism.

Oddly, the questions I get from men are frequently nostalgic. They are curious about insects and other arthropods they saw decades earlier. One gets the impression that (a) they have too much time on their hands and (b) they are thrilled that the Internet now gives them the opportunity to pose such questions to an expert that was previously less accessible.

The challenge now is to increase the opportunities for interaction between the scientific community and the general public, and improve the accuracy of information available on the Internet and through broadcast media. We need to fairly compensate science writers for providing just those services, but that is a topic for another day.
