Non-Venomous Spiders

Common House Spider

House spiders are among the most common in Chico, CA. These tiny, harmless arachnids can be seen near windows and light fixtures and in dark corners of rooms. They typically feed on small insects and build their webs where they can easily find food. House spiders range from 4-10 mm long and have a dark brown coloration with yellowish markings on their legs and abdomen. Although these spiders are not considered dangerous, they may bite if threatened or provoked. The bite is usually mild and does not require medical attention, although some people may experience localized pain or itching for a few hours afterward.

California Trapdoor Spider

The California Trapdoor Spider is usually brown or black and can reach up to 1 inch long. They are distinct for their burrowing habits, as they build their webs underground and use the entrance to their tunnels as a "trapdoor" to quickly ambush any potential prey. They feed mainly on small insects and are considered harmless to humans.

Venomous Spiders

Brown Recluse Spider

The Brown Recluse Spider is a species found mainly in warm climates of Southern California, such as Chico. This spider is small and light brown with a dark violin-shaped marking on its back. The venom from this spider can cause severe skin lesions and fever-like symptoms if it bites humans or animals. It is essential to take precautions when encountering this spider, including wearing gloves when handling objects in dark places or under furniture where the spider may be hiding. Additionally, it is important to keep your home free from clutter, as that could provide shelter for the Brown Recluse Spider. If you think a Brown Recluse Spider has bitten you, seek medical attention immediately and bring the spider with you if possible to identify and treat it effectively.

Black Widow Spider

The Black Widow spider is a dangerous, venomous arachnid that can be found worldwide, including in Chico. These spiders are easily identified by their glossy black bodies and bright red hourglass marking on the underside of their abdomens. They construct cobwebs in dark corners or crevices and feed mainly on small insects. The venom from a Black Widow bite can cause severe pain and muscle spasms; in extreme cases, it can be fatal. If you think a Black Widow spider has bitten you, seek medical attention immediately.

How to Treat a Spider Bite

Spider bites can range from mild to severe, depending on the type of spider and the amount of venom injected. If you think a spider has bitten you or someone else, taking precautions and seeking medical attention as soon as possible is vital.

First, remain calm and try to identify the spider if possible. It is important to know if it was a venomous spider like the Brown Recluse or Black Widow. If you can capture the spider, put it in a sealed container and bring it to the hospital. If the bite is on an arm or leg, try to keep it below heart level to slow the spread of venom.
