CHARLOTTESVILLE, VA (CVILLE RIGHT NOW) – October is when spiders often become more noticeable. Webs appear across porches, spiders show up in basements, and one may suddenly race across the bathroom floor. So why are they entering your home?
Spiders don’t move into homes because they like houses. They move in because houses contain food. If you’re seeing more spiders, look for the insects attracting them.
Spiders Go Where the Food Goes
Spiders prey on insects and other small arthropods, including flies, mosquitoes, moths, ants, beetles and crickets. A spider in your basement, garage, crawl space, attic or near a window may have found a reliable hunting ground. No prey. No reason for the predator to stay.
That’s why removing a spider or knocking down its web may not solve the underlying problem. The food source may still be there.
Why Fall Can Make Spiders More Noticeable
As temperatures change, insects may enter Central Virginia homes through gaps around doors and windows, damaged screens, foundation cracks and utility openings.
Exterior lights can attract flying insects near doors, windows and porches, creating feeding areas for web-building spiders. Moisture in basements, crawl spaces and other protected areas can also support insect activity.
That spider in the corner may be signaling one thing: There’s food here.
The Spider Web Is Only What You Can See
Removing a spider does not remove the insects attracting it. If another appears a few days later, inspect the surrounding conditions. Are insects entering around windows? Are pests gathering near exterior lights? Is moisture contributing to activity? Do cracks or gaps need attention?
Addressing those conditions is often more effective than treating each spider as an isolated problem.
What About Virginia’s More Concerning Spiders?
Most spiders homeowners encounter are more frightening than dangerous, and they help control insect populations outdoors. Still, avoid handling spiders you cannot confidently identify. Virginia is home to medically significant spiders, and suspected bites or unusual reactions should be evaluated by an appropriate medical professional.
For pest-control purposes, the best approach is identification, inspection and determining why spider activity is occurring in the first place.
