There are over three thousand six hundred species of spiders in the United States and Canada. Thankfully, only a handful care to share your home with you. If you live in St. Louis and have spiders, chances are they're harmless, and usually considered a nuisance pest. After all, who likes having a spider slowly creep down the wall while they're taking a shower? Not many.
Here is a list of harmless spiders you may see hanging out around or in your home: garden spiders, woodlouse hunters, jumping spiders, nurseryweb spiders, wolf spiders, funnelweaver spiders, and crab spiders. These spiders don't generally bite, and if they do, they're venom is virtually harmless to humans.
It is not uncommon, though, for a black widow or brown recluse to seek refuge in your home. These spiders should be dealt with immediately. Like other spiders, they are not aggressive, but they can bite, and they both have a venom that is potentially dangerous.
Where will I find spiders in and around my home?
Spiders feed on insects, and all spiders love moisture. The larger the spider, the more they need of both. If you have a spider in your home, they are usually in your basement, especially if it tends to get cool and damp. It is a good idea to routinely check your basement, and clear out the spiders and their webs. Spiders can lay hundreds of eggs. Granted, when those eggs hatch, very few babies live to adulthood, but that is still a lot of spiders.
Another common place to find spiders is in your kitchen. If you have fruit flies or house flies, spiders will thrive. Keep your trash covered to reduce the number of house flies. And keep your fruit in the fridge, to reduce the fruit flies. Don't leave dishes sitting out, which attract other tasty bug treats for the spiders. And use a broom to routinely sweep the webs out of the corners of your kitchen, near the ceiling.
As a general precaution, always shake your shoes and clothing before putting them on. Spiders aren't aggressive. They usually only bite when they feel threatened. Squishing your foot into a boot where a brown recluse has taken up residence does tend to produce that threatened feeling. So avoiding that is a good idea. Peel back the covers on your bed before sliding in. It is not uncommon to find a spider already tucked in for the night.
Spiders are more likely around the exterior of your home: the porch, in the garage or shed, and near wood piles. As a standard practice, you should have a pest control professional do an exterior barrier treatment to keep them from entering your home. They can get in underneath your lower siding, through cracks in your foundation, down chimneys, and through exterior molding. Functioning screens and door sweeps help, but they don't offer complete protection.
