What You Need To Know About False Black Widow Spiders

What do false black widows look like?

False black widows, often confused with true black widows, are medium-sized spiders with a body length of about 1/4 to 1/2 inch. They are usually dark brown or purplish-black in color, with a bulbous abdomen that lacks the red hourglass marking found on true black widows. They may have light-colored markings on their back.

What do false black widows eat?

False black widows feed on insects and other small arthropods, which they capture in their sticky, irregularly shaped webs. They paralyze their prey with venom before consuming it, helping to control insect populations in their environment.

What sort of habitat do false black widows live in?

False black widows prefer quiet, undisturbed areas like sheds, garages, attics, and under rocks or logs. They often build their webs in dark corners, under eaves, and in cracks or crevices around homes and buildings. They are commonly found in both urban and suburban environments.

How do false black widows commonly behave?

False black widows are not aggressive and will usually retreat when disturbed. They only bite in self-defense, and their venom, while painful, is much less dangerous than that of true black widows. Their bites may cause localized pain, swelling, and redness, but serious reactions are rare.

Did you know this about false black widows?

False black widows have been known to survive in a wide range of climates, from temperate to tropical regions. Despite their fearsome reputation due to their resemblance to black widows, false black widows are generally not considered a significant threat to humans. However, they have become an invasive species in some regions, and their bites can cause minor discomfort similar to a bee sting.

Understanding False Black Widow Spider Infestations

Understanding false black widow infestations is key to managing them effectively. These spiders typically have a dark brown to black body with a slightly bulbous abdomen, lacking the iconic red hourglass marking of true black widows. They tend to spin irregular webs in dark, sheltered areas such as basements, attics, sheds, and garages. Though false black widows are generally non-aggressive, bites may occur when they are accidentally disturbed.
