Black Widow Webs and Prey

Black Widows preferer temperatures of 70 degrees or higher, making the desert a great place for these spiders to call home. Their webs are usually ground level and built during the night time hours. These webs are typically different than other webs as they are not symmetrical. After the web is completed they are about 12 inches in diameter.

These webs are use for home and to capture prey. Like most spiders, they feed on arthropods like ants, cockroaches, and spiders.

Female black widows have been known to consume males after succesfully reproducing.

Black Widows Preferred Living Arrangement

Black widows enjoy dry and dark location, Viva Las Vegas! To make it worse, they typically search for warmer climates. They tend to establish themselves in protected areas like under stones or in tree stumps. They can all make a home out of man made structures like sheds, barrels, and other dry areas that mimic the indoors. They are attracted to these places because they like the dimly lit areas that they provide. This is the reason you may find them in your garage, basement, and crawl spaces.
