Most of us know that not all spiders look alike, but we also don't tend to look closely enough to know which spider is which. To effectively find and control common house spiders, though, it's helpful to know which type you're dealing with. As its name suggests, the common house spider is the spider most often seen in homes in the United States. They like to build webs in hidden areas of the home, such as attics, basements, sheds, and barns.
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. They are orange to dark red on the legs and head space with a yellow/brown or beige abdomen. Females can grow to 10.5mm in body length and are dark in color with a round bulb-shaped abdomen.
Highly common in the summer, these spiders are very active around the year in warm climates. The reproductive cycle of the species is dominated by the female. The black marks on the species are seen in the form of fine lines that lead towards a central yellow stripe.
If you suspect the spider you're seeing is a brown spider, give it space. Luckily, they are not aggressive and are not likely to bite unless pinned against skin. It is most common for brown recluse bites to happen on the arms, hands, and feet while getting dressed or cleaning storage areas. These bites can often go undetected until hours later when the discomfort sets in.

The main way to prevent a spider infestation in your home is to make sure they don't have any entry points, like cracks and poorly screened windows or doors. If you find spiders in your home, contact a pest management company, so they can conduct an inspection and create a control plan. Generally, the top part of the abdomen has a dark, v-shaped mark that runs down to its midpoint. Jumping spiders are diurnal, and particularly abundant in grassland and prairie environments, where they prey on small insects.
Call a professional pest control service immediately if you suspect black widow spider. Common house spiders in California can be a nuisance but they pose no dangers to humans. These insects select their sites randomly and start creating a tangled web. If a web does not get a prey, they select another site and build a new web. It is good to know that the most common types of house spiders found in California homes cause no harm. They, in fact, prey on pests and keep the place free of flies, roaches and millipedes.
