"Getting Rid of Black Widow Spiders"
FREE INSPECTION | SCHEDULE TODAY!
Recognize a black widow spider. Black widow spiders are found across the U.S and Canada, and in other temperate regions around the world. They are the most venomous spiders in North America. The female is the easiest to recognize — and the most dangerous. She is coal-black, with a spherical abdomen and a red hourglass-shaped mark on her belly. Her body is approximately half an inch long, but she has a total length of 1.5 inches (3.8 cm) with her legs extended.
The male is about half the size of the female and is brown or grey. He usually has several red dots on his abdomen and may have a yellow or red band across his back. Male black widow spiders are not venomous.
Young black widows, known as spiderlings, are white or yellow-white when they first hatch. They become darker as they grow. They may have yellow or red patches across their backs, resembling the adult male. It is impossible to tell male and female spiderlings apart. At this stage, both are harmless to humans.
If you have found a large number of Black Widow spiders in your house or yard, it may be wise to call PermaTreat who can effectively and efficiently eliminate the entire Black Widows population. This is particularly recommended if you have small children, elderly people or pets living with you, as these groups are more likely to be seriously affected by a bite.
