Spiders are not insects, but arachnids. They have two body parts—a head and an abdomen—and a total of eight legs. Unlike insects, spiders do not have antennae or wings, and are well-known for the elaborate webs they build to trap their prey. Spiders are found throughout the continental United States, and their presence in kitchens, attics, and garages is extremely common.
Large spider infestations typically begin when a spider egg sac is unwittingly carried into a home on a piece of furniture, or any other item, that has been stored in a dark area for an extended period of time. These sacs typically carry a large number of eggs, and can result in an unpleasant surprise if they break open while you’re around. If you believe you have spiders inhabiting your home, check for webs and egg sacs in these common areas:
- Room corners
- Cracks or crevices in walls
- Older furniture
- Window corners
- Moist areas in sheds or basements, particularly near plumbing
Having an infestation of spiders can be frightening, and homeowners are right to be concerned. Large populations of spiders in your home typically indicate that there are other insects present as well, since spiders only create homes where they are able to find a consistent food source. For this reason, the best form of spider control is often to simply exterminate the other insects present in your home. Spiders can be useful in controlling these other insect populations, but nevertheless their presence can be worrisome and should be addressed immediately upon discovery.
