Domestic House spiders are all over North America, as far north as Maritime Canada and as far south as Louisiana. As long as its web is undisturbed, they will usually hide in the funnel area, and not respond. They rarely, rarely bite, but if they do, it’s completely painless. They feed on the small insects they trap in their webs, and can live as long as seven years. Both Daddy Longlegs spiders and Harvestmen are found on every continent, except for Antarctica where is is too cold for them to survive.
Not only does it lack the black widow's red hourglass, however, but its bite is more like a bee sting. Despite their fearsome reputation, black widow spiders are not typically aggressive. Still, knowing the potency of their venom, I cautiously moved my belongings away from it, giving it plenty of space. I decided to leave the spider undisturbed, recognizing its role in controlling pests like flies and mosquitoes. They are commonly known by their violin-shaped marking on their cephalothorax. They are brown in color, as their name suggest, and have six eyes that are arranged in a triad.
Their presence in homes can help in reducing the number of pests, making them an ally in natural pest control. To prevent and control common house spider infestations, start by keeping your home clean. Regularly vacuum, dust, and sweep to eliminate spider food sources, such as insects. Inside structures, house spiders are most likely to be found in upper corners, under furniture, in closets, angles of window frames, basements, garages, and crawl spaces.

So the next time you discover a spider in your house, remember that they are generally just looking for a safe place to live while offering you their pest control services. American grass spiders are a type of brown funnel weaver spider with an elongated, oval brown body. Identifying features of the grass spiders are the distinctive dark brown bands running down its cephalothorax, mottled brown abdominal patterns, and spiny, orangey legs.
But, the bites are more likely from the similar-looking desert grass spider (Agelenopsis aperta), also commonly found in outdoor spaces in California. The hobo spider is a small brown spider with a characteristic herringbone pattern on its abdomen. The pale brown spider also has identifying features of two lines on the cephalothorax, chevron markings on its abdomen, and eight brown legs. Also called the daddy long-legs spider, the long-bodied cellar spider is a common arachnid found in Californian homes. The brown spider has a slender, tear-shaped abdomen and a small head.
If you notice one spider, seek a professional exterminator at the earliest because it can be a sign of an infestation. The spider gets its name from its crab-like appearance and ability to walk sideways and forward. Let’s look in more detail at the different types of spiders living in California.
Keeping things short and sweet, here are a few spider myths that need to be debunked.

There are thousands of different species of Harvestmen with different scientific names, but they all belong to the Opiliones family. While Russell says these spiders “may bite in defense,” it shouldn’t cause any issues for you.
Most fishing spiders eat insects, but some species can catch small fish. And even though they have highly toxic venom that is 15 times stronger than a rattlesnake, they are not aggressive. The Black Widow only bites defensively if the web is disturbed, and they RARELY bite humans. Daring Jumpers are hunting spiders that like open areas to stalk and chase down prey.
