Spiders In Denver: How To Keep Them Away From Your Home

If you’re like most of us, the thought of sharing your home with arachnids, whether they’re relatively harmless house spiders or the more nefarious black widows, is not really all that appealing. Unfortunately, there is a plethora of spiders in Denver, more than enough to go around in fact. So how do you keep them away from your home? What steps do you take if they’re already building webs on the porch or moving about inside? Read on to find out.

What attracts spiders in the first place

Spiders eat insects. As we mentioned in this blog post about spring pests in Denver, there are plenty of bugs around now that we’ve officially transitioned from winter to spring and insect populations are only going to increase as we move into summer. Connecting the dots, you’ll see bugs on your property equals spiders on your property. 

Easy access to your home isn’t necessarily what attracts spiders, but it certainly makes them more likely to infest. If you leave your garage door open, don’t cover windows with screens, leave gaps, cracks, or openings un-sealed, and don’t seal up/close other potential entry points, you’re practically inviting insects and the spiders that love them in.

Homes that have moisture issues or higher humidity levels than more modern ones, clutter, and plenty of dark, undisturbed areas also attract spiders.

The key to spider prevention in Denver

If you want to keep spiders out of your home, here’s what you’ll need to do:

  • Eliminate insect populations inside your home (we can help with this!)
  • Seal all openings from the foundation to the roof to keep all pests out
  • Shut outdoor lighting off when not needed, as this attracts bugs, which attract spiders
  • Correct moisture and humidity issues
  • Clean the interior of your home regularly and keep a tidy yard
  • Remove clutter, especially in storage areas where there is less foot traffic
  • Keep the garage doors closed when not in use
  • Replace window screens that have holes, rips, or warped frames
