Like all species of spiders, black widow spiders are arachnids. They are a beneficial pest because they feed on and help to control populations of nuisance insects. You can identify a black widow spider by its glossy, black body and legs, and a unique reddish-orange hourglass-like shape on the belly. They also have eight legs, eight eyes arranged in two rows of four, and a comb foot (a row of curved bristles located on the hind pair of legs) that allows them to wrap their prey in silk.
Yes, black widow spiders are one of the few species of dangerous spiders living in the United States.

Properties with gardens, shrubs, trees, and grass often have an abundant supply of insects and therefore spiders hunting them.

When the weather outside is cooler, these spiders seek warmer conditions, sometimes choosing to live in our homes and garages.
