This makes the small brown spider easy to mistake for a desert recluse, brown recluse, or common house spider. It is one of the most common spiders found in California homes. The California ebony tarantula is a large, hairy spider with a fuzzy body and legs in shades of brown and ebony. The brown and tan spider has a huge leg span of up to 5” (130 mm).
Half-edged Wall Jumping Spider
The false tarantula is a large and intimidating spider with a silvery-brown appearance. The large arachnid has a sizable egg-shaped abdomen, a large head area, and long, robust hairy legs. These characteristics give the spider the appearance of a tarantula. However, it’s a member of the funnel-web spider family Nemesiidae.

Western Black Widow
Gem-shaped orbweavers are also known as cat-faced spiders and are common outdoor spiders. Both have brown on the front of their head space and legs with a mottled gray abdomen with pale chevrons near the back. They have a red patch between the eyes and some red spots on their bodies. They have white oppressed hairs in the eye region and six chevron-like markings on the abdomen, which all point forwards. Their color ranges from black to purple-brown with light-colored markings.
Not only does it lack the black widow's red hourglass, however, but its bite is more like a bee sting. Many jumping spiders have red or white markings on their abdomens and can be confused for black widows. Jumping spiders, however, are not dangerous and are actually beneficial, as they enjoy hunting and pouncing on nuisance insects.
However, the common house spiders are beneficial in the home because they feed on flies, ants, wasps, and mosquitoes. The two most venomous types of spiders in California belong to the genera Loxosceles and Latrodectus. Therefore, widow and recluse spiders are considered the most dangerous in the western US. The three types of harmful, venom-filled spiders are the western black widow, desert recluse, and Chilean recluse. In this article, spider measurements are typically of body size, not leg span. Therefore, spiders with long legs and small bodies, like the brown widow spider, will appear significantly larger.

To complicate matters further, house spiders come in lots of shapes and sizes. The types in your house depend largely on where you live, although humans have helped many species spread around the planet, especially those from Europe. Some people think of spiders as insects, lumping them in with six-legged invaders like roaches or ants. But they're not insects, and they don't want to raid our cupboards.
As mentioned earlier, spiders are a potent defense against agricultural pests like aphids, moths, and beetles. House spiders offer similar benefits indoors, helping suppress a wide variety of insects without the need for synthetic insecticides. Since spiders are often found trapped in sinks or tubs, many people assume that's how they got inside. But modern drains feature sediment traps that would prevent spiders from passing, Crawford points out.
These orbweavers create small orb-shaped webs which are lined with debris. They are small and well-camouflaged spiders, which sit in the center of the web with legs tucked upward, so they blend in with the debris. This wolf spider from the Lycosidae family is common in North America with a cosmopolitan distribution. They build large orb-shaped webs, where the spider hangs upside-down waiting for prey to get ensnared. They are commonly found inside homes and while they are not considered dangerous, they will give a painful bite if threatened. They are not harmful to humans and will usually flee rather than be aggressive.
The cross orb-weaver spider is commonly found in southern gardens, meadows, and wooded areas in the southwestern United States. These web-spinning orange spiders catch prey in their large, wheel-shaped ornate webs. The cross orb-weaver spider is a distinctive orange spider with a white cross-like pattern on its abdomen. Identifying features of this unusual spider are its yellow and orange banded leg covered in spines, a small head, and two orange chelicerae.
The brown widow spider is a small spider with tan and brown mottled patterns on its back. Like all widow spiders, this venomous arachnid has a distinctive orange hourglass mark on the underside of its abdomen. In addition, the small biting spider has yellowish and black banded legs.
The noble false widow has a brown bulb-shaped abdomen with cream markings, that are similar to a skull shape with red to orange colored legs. Cellar Spiders eat insects and other spiders, but they find ants to be a particularly tasty treat. Like Wolf Spiders, the mother Cellar Spider carries her egg sac around with her, except that she carries it in her jaw rather than attached to her abdomen. Chances are, if you have a house, you have a cellar spider somewhere in the dark corners of your basements, attics, and cellars. They tend to build webs in the corners of your home, especially near a window. They capture insects in their webs, inject them with venom, and then save them to be eaten later.
Despite its menacing appearance, the Carolina wolf spider is not aggressive toward humans and will generally only bite if provoked or threatened. Because of its light brown color and distinctive markings, it’s easy to mistake the hobo spider for a brown recluse spider. However, unlike the hobo spider, the brown recluse isn’t found in California. 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.
It’s a myth that the infamous brown recluse spider (Loxosceles reclusa) is found in California. Researchers from the University of California say that brown recluse spiders have never been able to establish populations in the Southwest. Therefore, painful spider bites in California are likely from black widows or the desert recluse (Loxosceles deserta). These spiders are commonly found in residential areas, where they construct their intricate webs in corners, crevices, and ceilings. Grey house spiders are prevalent in urban and suburban environments, particularly in regions with moderate climates. They have successfully adapted to human dwellings, making our homes their own.
As their name implies, these types of spiders have a gray base color. Males are partly gray and partly black, with additional brown or orange hairs on the tip of their abdomen. Aggressive behavior of females towards males is also seen in this species. Males may attempt to make their way on the female’s web to live and mate. Females of this species are known to build spider webs while males are often found nearby.
Although this small brown spider only measures 0.08” to 0.39” (2 – 10 mm), it has an enormous leg span of 2” (50 mm). In addition, the small spider has six eyes arranged in groups of three. Striped lynx spiders range from orange, brown to cream with females having stripes on the head space and abdomen. Females are lighter in color with more brown, along with a larger head space and abdomen. Females have two black bands and a thin white stripe on their abdomen and a wide black stripe on either side. Hairs with spot markings, the legs are purple to brown with hairs that form a stripe on each leg.
