Are The Brown Recluse Spiders In St. Louis Dangerous?

October 31, 2021 - Spiders

You’ve probably heard of brown recluse spiders and how they are one of two dangerous species in the United States, with the other being the black widow. But did you know brown recluse spiders are the most commonly misidentified? They are light brown with a dark violin pattern on the cephalothorax, but many spiders in St. Louis homes or businesses have similar features.

To help you better identify brown recluse spiders, here is what to look for:

  • No bigger than ½ of an inch; if it is any bigger, it is another species
  • Solid colored legs with hairs, if it has banded colored legs and spines, it is another species
  • Six pairs of eyes with one pair in the front and two pairs on the sides, not eight pairs
  • Uniform coloring on the abdomen, if it has two colors, it is a different species

Another identifier of brown recluse spiders is their web. It will be a messy web built in a secluded area. It doesn't belong to a brown recluse if it has that classic wheel shape web and is out in the open.

Because the brown recluse is medically dangerous to people, you should seek medical attention if you believe you have been bitten. The same goes for children and pets. Symptoms of a brown recluse bite can include pain and skin irritation around the bite site, nausea, joint pain, fever, chill, and more.

This species is not aggressive and only bites a person or animal if they feel threatened. Unfortunately, spiders can feel threatened by someone unknowingly sticking their hand a little too close to their web. This is not something you want to risk happening, especially if you have pets or people living on your property.

While pest prevention is dependent on many factors, you should do as much as you can to prevent pests like the brown recluse from making a home on your St. Louis property.

Best Spider Prevention Tips

It might seem like you are defenseless against spiders. Maybe you’ve spent a lot of money on spray that only gets rid of one spider at a time, but hope is not lost. The following are tips from the experts at Roberts Pest Control to keep brown recluse spiders away:

  • Keep storage spaces like basements, sheds, garages, and closets organized and free of clutter to reduce potential brown recluse hiding places. 
  • Keep woodpiles away from your house and remove other yard debris such as dead trees, brush, and leaves.
  • Seal the gaps around where pipes and other utility lines enter your home.
  • Use door sweeps on exterior doors.
  • Keep plants from overflowing or growing excessively, as this can provide the perfect place for a brown recluse to build their web right outside your home.
