States Where Black Widow Spiders Are Most Likely to Be Found

Black widow spiders are notorious for causing fear due to their venomous bite. These small black spiders, recognizable by a red hourglass marking on their abdomen, can theoretically be deadly, though fatalities are extremely uncommon. With prompt medical care, recovery from a bite usually occurs within a day or two.

Despite the low risk of death, encountering a black widow in your garden or yard is something to avoid. Knowing where these spiders thrive can help you take precautions to reduce the chance of an encounter.

Black widows are present in almost every U.S. state except Alaska, but their numbers vary widely. They thrive in warm, dry climates with rich ecosystems, which makes states like Texas, Florida, Georgia, California, and Arizona hotspots for these spiders.

Several black widow species exist. The southern black widow is common across the southeastern United States. Northern black widows differ slightly, displaying red spots or broken hourglass shapes on their abdomen, and are mostly found in northeastern states. Western black widows favor arid environments and are prevalent in western states, sharing the classic hourglass marking of their southern counterparts.

Where Black Widows Live

Southern black widows typically hide in dark, secluded spots such as under rocks, in wood piles, inside rodent burrows, or in the corners of garages and sheds. Northern black widows prefer similar shelters including hollow logs, stacked wood, and rock piles, and they often take refuge in seldom-used buildings like abandoned attics or storage sheds.

Western black widows have adapted well to urban settings. They often inhabit areas rich in insects, including garages and waste disposal sites, following chemical trails left by their prey.

Preventing Black Widow Encounters

Black widows are generally nonaggressive and bite only when threatened. They prefer to escape rather than use their venom. The best way to avoid them is to eliminate potential hiding places around your home. This includes clearing debris piles, regularly sweeping, vacuuming, and dusting areas that are not frequently used, such as attics and tool sheds.
