Ask the Bug Doc: Why Am I Seeing Spiders Everywhere?

Dr. Nancy Troyano

I am seeing spiders everywhere in my house. Why are there so many and should I be concerned?   

When the autumn hits, it seems like spiders are literally coming out of the woodwork. You notice more spiders and webs in the corners of your home and all around your yard.

Why do spiders seem to run more rampant around the fall? Apparently, science has a lot to do with the answer.

Many spiders have a seasonal timetable that specifically coincides with their mating season. Spiders hatch in the spring, reproduce and subsequently die in the fall. So while spiders typically lie low in the early summer (mostly in an effort to keep from being eaten), by August, the survivors are large enough to start spinning webs so that they can mate.

Although spiders appear to be scary, it’s important to remember that most spiders are harmless. In fact, of the 3,700 species of spider found in North America, very few of those are actually toxic to humans.


If you’re seeing a lot of spiders, chances are there are some inconspicuous areas of your home where they are entering. Your Ehrlich specialists can identify the types of spiders in your home and identify the most likely points of entry. He or she can also recommend or even help seal these gaps and cracks to keep all types of pests from making themselves cozy in your home.
