black widow spider found in st. louis

Missouri is home to two of the deadliest spiders in the United States, the black widow and the brown recluse. The black widow has potent venom that can have you heading to the hospital, and the necrotic properties in the venom of the brown recluse can lead to disfigurement, if left untreated. We're sure you agree that these are two spiders you don't want to have crawling around your home. But, if you want to keep them out, here are a few questions you should be asking.

Is my home attractive to poisonous spiders?

There are conditions that attract black widows and brown recluse spiders to a home. Spiders are only concerned about two primary factors. They are looking for a spot that has the food they eat, and they want the location to provide them with the shelter they need. If your home has food sources that poisonous spiders dine on, they will be lured in. Black widows eat grasshoppers, beetles, mosquitoes, and other insects. Brown recluse spiders are looking for cockroaches, crickets, and other large bugs. Since both of these arachnids feed on big bugs, the fewer you have around your home, the better off you'll be. That is why one of the best things you can do to keep poisonous spiders away is to keep your lawn mowed and weeds pulled up. It is also a good idea to not have clutter in your yard, especially stacked construction materials. These are ideal places of shelter for spiders.

What places do I need to protect against poisonous spiders?

When these two spiders come onto your property they will be looking for quiet places to hide. Natural hiding places are under flat rocks, inside logs, and in large roots beneath trees. But, there are physical structures they will like more, such as outbuildings, sheds, garages, and attic spaces. Once inside a home, they will hide in quiet and undisturbed places like closets, crawl spaces, cellars, underneath furniture, and inside stored boxes.

Is there anything I can do to keep poisonous spiders out?

There sure is. Sealing up cracks in your exterior walls using a caulking gun is a great place to start. It is also a good idea to make sure all your screens, door sweeps, and weather stripping are in good working order. The fewer entry points spiders can find, the better chance you have of keeping these spiders out.

The best way to safely control poisonous spiders is to have ongoing pest services for your home. Fewer bugs around your exterior walls mean less incentive for black widows and brown recluse to come in close, and a limited and focused use of insecticides will ensure a barrier of defense those spiders will have a hard time getting through.
