Perhaps one of our readers will have an idea how to classify your Spider. Hi Joanna, We believe this might be a male Giant House Spider, Tegenaria duellica, based on some images posted to BugGuide. We are sorry you had to wait so long for a reply, but summer is a very busy time for us.
Golden Silk-Orb Weaver (Banana Spider)
Tepidariorum belongs to the same family (Theridiidae) as the notorious black widow spiders (Latrodectus spp.), it is not known to be dangerous to humans. Keep in mind that most spiders, including common house spiders, are shy and will avoid humans. They can even help control other household pests, such as flies and mosquitoes. Seeing a spider in your home may give you the heebie-jeebies, but they are common in California homes. For the most part, these house spiders in California are harmless, but it helps to be able to identify these eight-legged creatures when you see one.
Jumping Spiders Habitats and Habits
The western black widow is found throughout California—in hot, dry climates to mountainous terrain. Their favorite hiding places are in woodpiles, rock crevices, cracks in walls, and garages. This invasive species resembles the related false black widow (Steatoda grossa). However, it is larger, and the spider has more white dots on its black abdomen.

Though males may appear aggressive, they do not bite unless trapped, and their mouthparts are too small to easily penetrate human skin. Jumping spiders are not considered especially dangerous to humans, especially since they tend to prefer to flee rather than attack. The signs of an infestation are the funnel-shaped webs and the spider itself. Daddy Longlegs spiders do possess venom sacs, but their venom is very mild and virtually non-toxic to humans. Surprisingly, most people living in infested homes, even when the invasion is heavy, don’t report spider bites.

The Harvestmen, frequently called daddy long legs, are an easily recognizable site across the United States. There are thousands of different species of Harvestmen with different scientific names, but they all belong to the Opiliones family. They build tangled and messy webs close to the dwellings of human beings. The juvenile spiders hatch within a span of 7 to 10 days after which they gradually disperse. Avoid clutter in your home as it provides hiding spots for spiders. Keep your storage areas, such as closets and garages, organized.

But since they have been here so long, these spiders are now common, especially INSIDE homes. Females usually rest at the center of the web, facing downwards. They face their webs east-to-west to take advantage of the rising and setting sun and hang in the center with their dark underside facing south. All this allows them to gain as much warmth as possible, enabling them to stay active later in the year. Several different species are found here, and they are all large nocturnal spiders that find their prey around water. Lastly, many crab spiders have developed a mutualistic relationship with certain plant species since these spiders feed on and help deter harmful insects.
Additionally, the toxins in the venom aren’t dangerous to humans. The small brown spider has a bulbous abdomen, long legs, and the appearance of a brown widow spider. Read on to learn more about some of the most common house spiders, including which are harmless or potentially dangerous and what they look like. While not all species are visible in every state, each of them are common in homes across the country.
Today, you will learn about the most common spiders that live in California.
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. Brown Recluse Spiders are venomous, but they rarely bite unless provoked.
This spider is an invasive species in California, as it originates from Madeira and the Canary Islands.
Black widow spiders are prevalent throughout the region and can be identified by their shiny black bodies and distinctive red hourglass-shaped markings on their abdomens. Brown recluse spiders, known for their violin-shaped markings on their backs, also thrive in the southern states. On the less harmful side, American house spiders are found nationwide, but they tend to favor warmer climates like those found in the South. It’s essential to be cautious when encountering these spiders, particularly the brown recluse and black widow, as their bites may require medical attention. You can minimize your risk by avoiding cluttered areas, and wearing gloves when handling woodpiles or working outdoors.
Domestic House spiders are not a particularly aggressive species, preferring to retreat when confronted. For some people, a small white blister appears soon after the bite, the tissue may become hard, and develop a red, white or blue lesion. In extreme cases, the surrounding tissue can become gangrenous, leaving an open wound as large as a human hand, which can take eight weeks or longer to fully recover.
Every house, even the most well-maintained, has the potential for unwanted eight-legged guests—but you don’t have to put up with them. Use these tips to prevent common house spiders from turning your home into theirs. As a natural part of the ecosystem, house spiders play their role in keeping other pests in check.
