SpiderWhen to Call a Pest Control Specialist for Spiders

We at Bakersfield Pest Control have the knowledge and experience needed to spot spider infestation problems, and can even pinpoint where spiders gain access inside of your home. We are seasoned professionals who know how to combat spider infestations in ways that will significantly reduce the risk of future infestations. American house spiders, wolf spiders, and black widows are the three most common house spiders we control.

The American House Spider
American house spiders, also known as common house spiders, are stubby and tiny in appearance, and come specked with shades of brown and black. They typically measure about 1/4-inch long. American house spiders like to spin their web in wall crevices, behind doors, and in corners. They prey mostly on small insects that get caught in their web, but will sometimes prey on small lizards. They scurry away at the sight of humans, and will even play dead if they feel threatened. American house spiders have poor vision and will only bite if they feel threatened. Bite symptoms include itching and swelling, and are not fatal.

The Wolf Spider
Wolf spiders, also known as California wolf spiders, have long, thick legs, and are brown to black in color. Rather than spinning a web and waiting for small insects to enter their web, the wolf spider hunts on the ground, which is how they can easily enter homes. Since wolf spiders don’t spin webs, they carry their egg sacs with them under their abdomen. They can bite if they feel threatened, but are otherwise not aggressive. Bite symptoms are mild and include itchiness, swelling, nausea, and headaches.

The Black Widow
Female black widows are black, with a a red hourglass shape on their abdomen, whereas males are brown. Females are 1 to 1 1/2-inch long, and males are only half that size. Black widows like to spin webs in houses, garages, deck areas, and under crawl spaces. They typically feed on mosquitoes, beetles, grasshoppers, flies, and caterpillars. Female black widows are aggressive and are known to bite if humans go near their web. Black widows are the most venomous spiders in all of North America, and you should avoid any contact with them. It’s venom is reportedly 15 times stronger than that of a rattlesnake’s. Bites can be fatal to small children, the infirm, and the elderly. If bitten by a black widow spider, seek medical attention as soon as possible. Bite symptoms include pain, swelling, nausea, vomiting, chest pain, and fainting.
