Spider Identification & Prevention


What are spiders?

Spiders are predatory arachnids that out in nature provide an important service, which is to limit the numbers of nuisance and destructive insects. In controlled numbers, spiders are also helpful in our yards and often called "a gardener’s best friend." Yet when spiders get into our homes or take over our yards in large numbers, they become unwanted pests and need to be removed.

A spider’s two body segments, eight legs, and webs (though not all spiders build webs) make spiders pests that most people easily identify. Two species in our area that may be helpful to know a bit more about are the black widow spider and cellar spider. 

Black widow spiders are black, shiny spiders with a reddish hourglass marking on the bottom of their abdomen. 

Cellar spiders have a small cylindrical body and long skinny legs. They come in various colors, including pale yellow, gray, and light brown.

Are spiders dangerous?

In our area, an example of a dangerous spider is the black widow. If bitten by one of these spiders, their venom is potent enough to cause concern. A black widow spider bite should be treated by a medical professional. 

Cellar spiders and the majority of other spiders we run into daily are harmless to people. While they can bite us if they are being squished or otherwise threatened, the venom they possess isn’t strong enough to be medically significant.

Why do I have a spider problem?

You have a spider problem in your house because openings in your home’s exterior is allowing spiders to move indoors. Spiders are in your yard because there is plenty of prey for them to hunt and plenty of vegetation to hide in.

In California, spiders tend to be most problematic indoors during the fall season, not because they are trying to escape harsh or cooler weather, but because many of the insects they prey upon move indoors. They also move inside in the fall, searching for a mate and a safe place to lay their eggs.

Where are spiders commonly found?

Spiders don’t like to be in the spotlight. As predators, they want to stay hidden so they can surprise their prey. By nature, spiders are shy, reclusive creatures, and our yards, landscaping plants, and gardens provide them with plenty of hiding spots.

The exterior of homes, spaces under decks, inside outbuildings, and the clutter that generally collects within those structures are also regularly inhabited by spiders. 

After spiders move into your home, they tend to hang around if there is a water source and insects to hunt. Inside, some of the spider’s favorite hiding spots include crawl spaces, attics, basements, closets, and areas under furniture. The corners of bathrooms, kitchens, and windows also provide spiders with a place to build their webs.
