Common Spiders of Southeastern Washington

Spiders rarely bite humans as biting is merely their only form of self-defense, they'd much rather bite their prey. Spiders have eight legs and eight eyes. The size of the eyes and their placement on the head are key features to finding the spider's identity and classification. Some spiders live in webs made of silk, while others might live in old rotten wood, grass, or even in dark corners of your home.
  1. Brown Recluse

    • The brown recluse is brown in color and has a violin-shaped mark on its back. The recluse has six eyes arranged in three pairs on the head. They measure 2 to 3 cm in diameter. Their nests are found in attics, ceiling cracks, basements and in and under furniture. A recluse bite can result in serious medical complications such as disfiguring wounds and tissue deterioration. After being bitten by a recluse spider, a skin lesion will appear. Bites can often be misdiagnosed as impetigo, Lyme disease, diabetes or many other things if the bite is not actually witnessed.

    Hobo Spider

    • The hobo spider's defensive bite is only venomous 50 percent of the time; this is referred to as a dry bite. The hobo spider is more likely to create venom for prey than for defense. They measure about 1/2 inch in length. Their body is a light-tan color with stripes on their sides near their legs. The male's bite is more potent than the female's bite, and a lot like the recluse spider's bite. Within a few hours after being bitten, the area will become inflamed with a hard red spot. In a day or two blistering will appear at the bite site. Next, the blisters will burst, leaving open sores that look like targets. If the bite is not taken care of, the sores will scab over, with some becoming bigger and deeper. These sores may not heal completely for years.

    Black Widow

    • The black widow spider is shiny black in color with a red hourglass-shaped mark on its belly. It is about 3 to 4 cm in diameter. It may also have a line of red spots. The male widow's bite is not known to be dangerous, while the female's neurotoxin venom causes muscle tightening, cramping and chest pain with swelling at the bite mark itself. In about 2 days, the symptoms may subside and these bites rarely result in death.
