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.
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 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.
