With its moist and warm climate, the Bay Area sees many spiders year-round. Many people consider spiders to be one of the scariest animals on Earth. And while these creepy arachnids can look scary, most pose no immediate health risk to humans. However, seeing any type of spider in your home could be a red flag that other problems may require immediate attention. 

At Bay Pest, we know how to identify dangerous spiders in your home. Our Bay Area pest control specialists are also experts at finding and permanently eliminating all species of spiders.

Types Of Spiders Found Around The Bay Area

Two types of spiders are around the Bay Area. The first and most common type of spider you will find is the wolf spider, arguably one of the scariest-looking spiders in California. The wolf spider is one of the larger spiders in this area and can grow to be 1 ⅜ inches long. They have large, thick bodies and long legs. They can range in color from dark brown to tan and usually have light brown or yellow lines on their bodies. Their large bodies have a covering of fine hairs, so many people mistake them for tarantulas. Wolf spiders may look scary but are considered harmless to humans. They have venom, but unless you are allergic to it, a wolf spider bite usually results in minor pain and swelling that will go away on its own. 

The black widow spider is the other type of spider commonly in this area. They can measure up to 1 ⅜ inches long. They have solid black bodies that have a glossy appearance to it. They also have large, spherical abdomens with a red hourglass-shaped mark on the underside. The black widow is a venomous spider that can pose a health risk to humans. Their toxic venom could cause headaches, severe pain, and muscle spasms in some people. If you think you received a black widow spider bite, seek medical attention to ensure you don't develop severe symptoms. 

Should I Be Worried About Spiders Around My Property?

Spiders don't usually pose a serious health risk if they are in your home. Because black widows are not known to be aggressive, even if you have this venomous spider in your home, you are not likely to be in any serious danger. 

However, having spiders in your home could indicate other problems—for example, spiders like warm and moist areas. An uptick in spiders around your house could mean that you have a leaky pipe or another moisture issue in your home.

Also, spiders like to eat various insects, including ants, roaches, beetles, and more. If you suddenly see spiders around your property, you should also have your home inspected for any type of insect infestation.
