These hairy creatures are typically gray, black, or brown in color and grow up to almost one and a half inches. Wolf spiders are not aggressive, but if provoked, they will bite, causing redness, itchiness, and pain. This common house guest is typically dark brown or orangish-brown in color and has stripes on its legs. They can be found in dark, quiet spaces like cabinets and undisturbed rooms like attics, basements, and garages. Sealing potential entry points may not affect house spiders, since they don't sneak in from outside, but it could limit incursions by other spiders. And if it also prevents insects from getting inside, it may indirectly reduce your house spiders by limiting their food supply.
Are These Spiders Dangerous?
However, depending on the color of the flower where the small garden spiders hunt, the spiders can be white or yellow. 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 orange cross orb-weaver spider measures 0.26” to 0.79” (6.5 – 20 mm) long. The black and yellow garden spider is a large and striking arachnid with a distinctive black and yellow coloring. The spider’s identifying features are its egg-shaped black bulbous abdomen with yellow spots and black and yellow banded legs.
House Spiders in California
When trying to spot house spiders, it’s essential to look out for their webs. You can often find these in corners, cobwebs near windows and doors, or even in your garage or basement. Attics and crawl spaces are also common spots for spiders to set up their homes, as they prefer dark and secluded areas. Male and female spiders often exhibit differences in size, color, or markings. In many cases, females are larger than males, especially when it comes to reproductive roles, such as carrying egg sacs. As its name suggests, the common house spider is the spider most often seen in homes in the United States.
Brown Widow (Latrodectus geometricus)
They can’t find enough food or other spiders or insects eat them. Therefore, in this case, you don’t really have to worry about a large spider infestation. Sac spiders vary drastically in coloring and are sometimes confused with other spiders due to shades ranging from yellow to brown to green. It's a good idea to keep your distance from these spiders, as their venom contains cytotoxin and has been shown to be toxic to humans. Use a vacuum or broom to clean them up or hire a local IPM specialist.
Brown Recluse Spiders are venomous, but they rarely bite unless provoked. Many times this happens by mistake, when they get caught in bedding or clothing. The main sign of a Wolf spider infestation is actually sighting them. They can scurry under doorways, and a person can even carry a jumping one in on its clothing. Wolf spiders are common throughout all the U.S., but are particularly ubiquitous in Texas, California, and Missouri. Wolf spiders are not at all aggressive, and make quite good pets.

Wolf spiders are furry brown spiders with distinctive black bands on their abdomens. Identifying features of wolf spiders are their eight eyes arranged in three rows, banded furry legs, and a flattened head. The medium-sized brown spiders grow 0.4” to 1.4” (10 – 35 mm) in size. Many species of spiders have a reddish-orange appearance with distinctive black marks. These red-orange spiders are typically orb-weaver spiders or jumping spiders.
Harvestmen (Opiliones)
As their name suggests, the native spiders are known for their impressive jumping abilities. The California ebony tarantula is found in the deserts of California, Nevada, and Arizona. Despite their intimidating appearance, California desert tarantulas are not dangerous to humans. Instead, they tend to be shy and scurry away if you approach them. Wolf spiders seen outdoors are best left alone because they provide efficient insect control.
Surprisingly, most people living in infested homes, even when the invasion is heavy, don’t report spider bites. In 2001, more than 2,000 Brown Recluse Spiders were found a in a Kansas home, yet the residents had never been bitten, despite living there for years. Brown Recluse spiders can be identified by the violin-shaped markings on their back, which leads to their commonly being referred to as fiddleback or violin spiders. They only have six eyes arranged in pairs in a semicircle, as opposed to the regular eight. They can also be identified by their comb foot, a row of strong, curved bristles on the hind pair of legs.

Therefore, it’s always best to use gloves when working in the garden. Other names for the brown recluse spider include brown fiddler, violin spider, or fiddleback spider. Although the violin markings on its head are an identifiable feature, other harmless spiders also have similar markings. However, a unique characteristic of the brown spider is that it has six, not eight, eyes like most spiders.
It first appeared at U.S. shipping ports in the 1600s, and is now found across most of North America as well as Europe and western Asia. It ranges from 6 to 12 millimeters in length, with a reddish-brown "head" (the cephalothorax) and a pale, speckled abdomen. It builds funnel-shaped webs, and is known to prey on pest insects inside homes. To prevent and control common house spider infestations, start by keeping your home clean.
Here, we’ll briefly introduce you to some common house spiders that you may encounter. 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. If you have noticed dirty cobwebs in the corners of your walls, they could have been left by a common house spider.
Common house spiders usually feed on small insects and household pests such as flies, mosquitoes, ants and wasps. They can randomly attack grasshoppers, butterflies, cockroaches or other spiders depending on their size. If the prey is too agile, the spider will try shooting web at it from a distance before pulling the thread toward itself. Bigger females can also attract baby skinks inside their web by leaving fly remains hanging in it.
