Many spiders found around Bay Area homes and businesses are primarily a nuisance, but some species deserve additional attention. Knowing what type of spider you’re dealing with can help determine the best approach to controlling it.

Black Widow spiders are one of the spiders Bay Area homeowners should be particularly aware of. They prefer protected, relatively undisturbed areas and may be found around garages, sheds, wood piles, outdoor furniture, storage areas and other dark spaces around a property.
Because Black Widows can deliver a medically significant bite, homeowners should use caution when reaching into areas where these spiders may be hiding.
Learn more about Black Widow spiders, including how to identify them and where they are commonly found.

House spiders frequently build webs in quiet areas where they are unlikely to be disturbed. They may appear around windows, ceilings, garages, storage areas, corners and other protected locations.
Occasionally finding a spider indoors isn’t unusual. However, repeatedly finding spiders or webs can indicate that spiders have access to suitable hiding places and a steady source of insects to feed on.

Bay Area properties can also be home to Cellar Spiders, Crab Spiders, Garden Spiders, Ground Spiders and other common spider species.
Different spiders prefer different environments. Some build webs around structures and vegetation, while others hunt along the ground or hide in protected areas during the day. Identifying where spiders are living and why they are attracted to the property is an important part of developing an effective spider-control strategy.
Day & Nite Pest Control provides professional spider control for both homes and businesses throughout the Bay Area.
Spiders commonly hide around garages, patios, eaves, landscaping, storage areas and other protected spaces. Our residential pest control services help reduce spider activity while also addressing the insects and conditions that may be attracting them.
Spiders and visible webs around entrances, exterior lighting, storage areas and other high-traffic spaces can create a poor impression for customers and employees. Our commercial pest control services help Bay Area businesses control spiders and reduce recurring activity around their properties.
Seeing more spiders around your home doesn’t necessarily mean spiders themselves are the only problem. Spiders go where they can find food, and their primary food source is other insects. Homes with increased fly, mosquito, cricket, ant or other insect activity can naturally attract more spiders.
This can be especially noticeable around East Bay properties near open space, mature landscaping, hillsides and vegetation. Spiders may build webs around exterior lighting, eaves, patios, fences, shrubs and landscaping before eventually finding their way indoors through gaps around doors, windows and other openings.
Seasonal changes can also affect spider activity. You may notice more spiders at certain times of year as insects become more active outdoors or spiders search for protected areas around a home.

Effective spider control involves more than eliminating the spider you happen to see. When spiders continually return, there is usually a reason the property is providing them with food, shelter or access. Professional spider control focuses on identifying these conditions and targeting the areas where spiders are most likely to live and travel.
Depending on the property and level of activity, spider control may include:
We look for webs, hiding places and other signs that can help determine where spiders are concentrating around the property.
Treatment can focus on cracks, crevices, exterior areas and other locations where spiders commonly hide or establish webs.
Spiders are predators. When a property supports a large population of insects, it also provides spiders with a reliable food source. Addressing other pest activity can therefore be an important part of long-term spider control.
Gaps around doors, windows and other openings can allow spiders and the insects they feed on to enter the structure.
The goal isn’t simply to treat one visible spider. It’s to make the property less attractive to spiders and reduce the conditions allowing them to continually return.
Spiders typically choose locations that provide protection and access to insects. Exterior lights can be particularly attractive because they draw flying insects after dark. Where insects gather, spiders often follow. Heavy landscaping close to the structure can create another favorable environment by providing both shelter and insect activity near the home.

If you’ve removed spider webs only to see them return a few days later, there may still be conditions around the property supporting spider activity.
One of the biggest factors is insect activity. A home with plenty of insects provides spiders with exactly what they need: food. Exterior lighting, thick vegetation, standing water, accessible garbage, flowering landscaping and other environmental conditions can increase insect activity around a property. Garages, storage areas and undisturbed outdoor spaces can then provide spiders with protected places to live.
This is why controlling spiders often means looking at the entire pest environment around the home rather than simply removing individual webs.
Pest pressures can vary considerably throughout the East Bay. Homes near hillsides, parks, creeks, open space and mature vegetation can experience different insect and spider activity than properties in more densely developed areas.

An increase in spiders can be related to increased insect activity, seasonal changes, favorable weather, nearby vegetation or spiders searching for protected areas. Because spiders feed on other insects, an increase in their food supply can also lead to increased spider activity.
Spiders are primarily attracted by food and shelter. Properties with abundant insects, exterior lighting, heavy landscaping, garages, storage areas and protected spaces can provide favorable conditions for spiders.
Professional pest control can help reduce spider activity by treating areas where spiders hide and travel while also addressing other insects that serve as their food source. Long-term spider management is generally more effective when both spiders and the conditions attracting them are considered.
Removing a web doesn’t necessarily remove the conditions that attracted the spider. If insects and suitable hiding locations remain, spiders can rebuild webs or other spiders may move into the same area.
Yes. Black Widow spiders can be found in the Bay Area and commonly seek dark, protected and relatively undisturbed locations. Garages, sheds, wood piles, outdoor furniture and storage areas are examples of places where homeowners should use caution.
