There are several species of spiders that can be found in homes throughout the state, and some of them are poisonous.

All of these species can be found throughout the state, and they all pose a serious health threat if their venom is injected into humans or animals.
Common Poisonous Spider in CA:
Black Widow Spiders
Black Widow spiders are the most common of the three poisonous spider species. They have a distinctive black color with a red hourglass pattern on their abdomen. Black Widows like to hide in dark, secluded areas and can be found outdoors around woodpiles, rocks, and other debris. They also like to hide in undisturbed places indoors like basements, attics, and crawl spaces. Black Widows are generally not aggressive and will only bite if provoked or threatened.
Brown Recluse Spiders
Brown Recluse spiders are the second most common poisonous spider in the United States. They have a light brown to yellowish-brown color and can be distinguished by the violin-shaped pattern on their back. Brown Recluses like to hide in dark, secluded places indoors, such as closets, attics, and basements. Unlike Black Widows, Brown Recluses are often more aggressive and will bite if disturbed.
Wolf Spiders
Wolf Spiders are the third most common poisonous spiders in the United States. They have a large, hairy appearance with dark brown to black coloring. Wolf Spiders are typically nocturnal and hunt their prey at night, often entering homes by mistake. They do not spin webs to catch their prey and are often found in attics, basements, and dark corners. Wolf Spiders may bite when threatened or disturbed, but the venom is typically nonlethal.
Yellow Sac Spiders
Yellow Sac Spiders have distinctive pale yellowish-green coloring and grow to a size of about half an inch long. Although their bite is painful, the venom contained within is not considered dangerous to humans, although it may cause irritation or some redness at the site of the bite.
Prevent Spider From Entering Your Home
To help prevent spiders from entering your home, make sure to seal up any cracks or openings in windows and doors. Additionally, keep clutter away from the exterior of your house, as this can provide shelter for spiders. Finally, consider using an insecticide around the outside of your home to discourage spiders from coming near. For professional spider control, contact Big Time Pest Control
