The males and females look different, but the females are the most recognizable. Females are about 1.5 inches long and shiny black with the tell-tale red hourglass marking on their abdomens. Males are about half the size of a female (0.5-0.75 inch long) and lighter in color with red or pink spots on their backs.
Insecticide For Black Widow Spiders
Most black widows will only bite when disturbed. However, since they build their webs close to the ground, they can easily come into contact with people and pets. While male black widow spiders can bite, it’s almost always the female who is responsible. Despite their small size, black widows pack a poisonous punch and their bites should be taken seriously. People bitten by a black widow can experience pain at the bite site, fever, nausea, and increased blood pressure. While bites are not usually fatal, anyone who has been bitten (especially a small child or elderly individual) should seek professional medical care immediately.

Prevent Black Widow Spider Problems
To prevent black widow spiders from moving into your yard and home, take preventative measures. Remove material, such as firewood piles where they might hide and always check firewood for hitchhikers before bringing it into the house. Eliminate clutter in storage areas, such as basements, attics, and closets. Keep plants and grass trimmed near your house and remove clutter and debris from around your house’s perimeter. Fix cracks in your home’s foundation, seal openings, and install screens and door sweeps to help prevent spider entry.
Insecticide For Black Widow Spiders
Considered one of the most dangerous and most poisonous spiders in North America, the Black Widow Spider (particularly the female Black Widow Spider) is very aggressive, especially when protecting their eggs or when feeling threatened.
Black Widow spiders are found throughout the U.S. and have been known to enter structures and hide in dark, undisturbed areas of the home. They are not social creatures and like to be left alone and not be bothered.
The Black Widow Spider can create its habitat either indoors or outdoors. When outdoors, Black Widow spiders usually live in tucked-away areas under stones and in firewood piles. They are often found in barns, outhouses, and sheds. Indoors, black widows like to hang around cluttered areas of garages, crawl spaces and basements.
