Why Are There So many Spiders In My Boise Idaho home

July 9, 2021

To say that spiders are a common occurrence in most Boise homes is an understatement. We have all had the not-so-pleasant experience of encountering those hairy eight-legged pests. Whether we like it or not, spiders will always be a part of our lives. Decreasing your spider population with a pest control regimen will allow you to relax in your home again. We won’t be able to help with your arachnophobia, but we can help with the frequency of sightings.

Spiders Common To Boise

There are more than 45,000 known species of spiders worldwide. They come in varied sizes and colors, but the same body type. Their webs can also be different depending on the habitat and desired prey. In Boise and the Mid-West in general, we have several that can be quite nasty, but most spiders are just an unwelcomed nuisance.

  • Common House spider: This species is non-aggressive and is not harmful to humans.
  • Wolf spider: This species is non-aggressive and is not harmful to humans.
  • Black Widow spider: This is an aggressive spider species. If bitten, seek medical attention.
  • Jumping spider: This non-aggressive spider is brightly colored and not harmful to humans.
  • Hobo spider: This species is non-aggressive unless cornered. It is venomous. If bitten, seek medical attention.

If you are bitten by a spider, please do your best to catch it. This makes it much easier for the doctor to identify the toxin. For the most part, spiders prefer to eat moths, flies, mosquitos, and sometimes other spiders. People are not usually on the menu.

Remove Spiders Food Source From Boise Home

This is easier said than done. Pests tend to find a way into even the most secure homes, and a spider’s instincts will lead him to spin webs where there is a high probability of catching a steady flow of prey. So, taking action to keep flying insects out of your home is the first logical step in spider prevention. Here are some ideas.

  • Check window screens for holes, rips, or bent frames.
  • Fill holes and cracks around the outside of the house.
  • Empty garbage frequently.
  • Keep outdoor garbage cans away from the house.
  • Store food in airtight, plastic containers.
  • Insulate pipes to avoid condensation.

Eliminating their food source will aid you in your objective. If you're seeing insects in your home, a spider problem is likely to follow as they see your space as a viable place to hunt and catch their next meal. Therefore, whether you're dealing with spiders or other unwanted pests, it’s wise to continue these practices to reduce pest activity in your Boise home.

Other Prevention Tips For Keeping Spiders and Their Prey Away

Where there is a will, there is a way. Maybe pests attend motivational seminars too. There is probably a meeting hall in your basement for their rallies and a group that meets Tuesday nights for the few that need a little extra help. That would certainly explain why they are so persistent at getting into your home.

  • Frequent de-webbing is probably the most effective and quickest way to deter the spider’s attempt to take up residence.
  • Keeping a clean and tidy home that is clutter-free is a definite help. Spiders dislike the smell of bleach or white vinegar.
  • The use of essential oils near suspected entry points makes your home far less inviting. Peppermint, tea tree, and eucalyptus oils are recommended.
  • Check the underside of furniture and dressers for egg sacs. Remove them.
  • Be sure that your door sweeps are in good repair.
