Spider Identification & Prevention

What are spiders?

Spiders are eight-legged predators that only feed on live prey. Spiders hunt a variety of nuisance insects other spiders, invertebrates, and some small vertebrates. All spiders have two body regions, fangs (chelicerae), and pedipalps that they use to produce silk for climbing, building their webs, lining their burrows, and wrapping up their prey.

Some of the most common spiders to invade properties in our area include black widow spiders, brown recluse spiders, house spiders, and wolf spiders.

Black widow spiders
Black widows have a red, hourglass-shaped mark on the underside of their abdomens, and some have light red or white markings on their abdomens and backs. Their round bodies are shiny and black, and their legs are very thin.

Brown recluse spiders
Brown recluse spiders are yellowish-gray to black with gray hair covering their abdomens; their legs are darker than their bodies. They have a distinctive, violin-shaped pattern on the top of their bodies and three pairs of eyes arranged in a semicircle.

House spiders
House spiders vary in color but are usually yellowish-brown with distinctive, dark chevron markings on their bodies and legs. These spiders have abdomens that are very round.

Wolf spiders
Wolf spiders have large, robust bodies and powerful legs covered in hair. They are dark brown with pale, yellowish markings. They are not web-building spiders; instead, they create burrows.

Are spiders dangerous?

In the United States, dangerous species of spiders include the black widow and the brown recluse. Care should always be taken around either species, as their venom is strong enough to affect a person's health although, with medical care, the adverse reactions can usually be easily managed. Nuisance spiders like house spiders and wolf spiders have venom that is not strong enough to cause significant health problems. While not dangerous, nuisance spiders are irritating to have on your property in large numbers.

Why do I have a spider problem?

Most outdoor spaces provide ample places for spiders to live, hunt, and hide. Once on your property, spiders will often find their way into your home or business through openings in exterior walls, the foundation, and the roof line. They move inside when following their prey; if you have a lot of spiders in your house, there are more than likely a lot of other insects in your home as well. Extreme weather conditions will also drive spiders indoors.

Where will I find spiders?

Spider infestations occur both inside and outside. Most spiders create webs to capture their prey or to use as a place to rest. Others, like wolf spiders, don't build webs; they instead burrow in the ground under rocks, trees, bushes, or woodpiles. Most web-building spiders build their nests in trees, shrubs, woodpiles, under decks, under roof eaves, and in doorways and garden areas. Brown recluse and black widow spiders build their irregular-shaped webs at ground level. Inside, spiders hide under upholstered furniture, in basements, closets, attics, under sinks, and in other quiet places.
