Spider control and extermination can be a major concern for homeowners - particularly for those who live in the southwest. There are about 3,000 species of spiders throughout North America, but the good news is that only two in the southern and western United States can cause serious harm when accidentally disturbed - the black widow spider and brown recluse spider.

Black Widow Spider
Black Widow Spider

Black widow spiders get their common name from the popular belief that the female eats the male after mating, a phenomenon which rarely happens in nature. These spiders can be found worldwide with five species established in the United States and are most recognized for the red hourglass shape on the underside of their abdomen. Although fatalities are rare, the black widow’s venom is reported to be 15 times stronger than a rattlesnake’s and can cause muscle aches and nausea.

Hobo Spiders

The common name for the hobo spider comes from its presumed method of expanding its distribution by hitching rides with humans along major highways in the Pacific Northwest. In fact, the hobo spider was introduced from Europe in the 1930s and has become established in at least 6 states since, displacing many native spider species as it spreads.

Wolf Spider

Unlike most spiders, wolf spiders don't hunt with webs. Instead, they chase their prey using their fast running ability. These spiders are often big and hairy which alarms some people, but they are primarily nuisance pests. Over 100 species of wolf spiders are found in the United States and Canada.
