Spiders in Bakersfield and the Central Valley - What Homeowners Should Know About Black Widows

By the Clark Pest Control Entomology Team

If you’ve spotted spiders in your garage, crawlspace, storage shed, or carport, you’re not alone. Across Bakersfield and California’s Central Valley, spider activity commonly increases as warm, dry conditions push insects - and the spiders that feed on them - closer to homes.

While most spiders are harmless and play a role in controlling other pests, some species, especially black widow spiders, can be concerning when they settle into areas where people store belongings or frequently work with their hands.

Understanding why spiders show up, where they hide, and how to prevent them can help homeowners reduce unwanted encounters.

Why Spiders Are Common Around Central Valley Homes

Spiders are attracted to environments that provide shelter, insects, and minimal disturbance. In Bakersfield and surrounding Central Valley communities, prolonged heat and dry conditions can increase spider activity around homes.

Common spider-prone areas include:

• Garages and carports
• Storage sheds and outdoor cabinets
• Crawlspaces and utility access points
• Woodpiles, cluttered storage areas, and cardboard boxes

Moisture sources such as irrigation systems, leaky hose bibs, or condensation around pipes can increase insect populations, which in turn attract spiders.

Black Widow Spiders - A Key Concern in Bakersfield

Black widow spiders (Latrodectus hesperus) are commonly found throughout Bakersfield and nearby Central Valley cities. Female black widows are shiny black with a distinctive red hourglass marking on the underside of their abdomen.

They prefer dark, dry, and undisturbed areas and often build irregular, sticky webs close to the ground. Typical hiding spots include garages, crawlspaces, meter boxes, sheds, woodpiles, and behind stored items.

Although black widows are not aggressive and bites are rare, their venom can cause serious reactions in some individuals. Homes with children, pets, or frequent garage activity should take sightings seriously and seek professional identification and control.

Other Common Spiders Found in the Central Valley

In addition to black widows, homeowners in Bakersfield, Delano, Shafter, Wasco, Tehachapi, Arvin, and Lamont may encounter:

• Cellar spiders (daddy long-legs) are commonly found in garages and eaves
• Wolf spiders, large fast-moving spiders that may wander indoors
• Orb-weaver spiders, outdoor web builders around patios and gardens
• Common house spiders that build tangled webs in quiet indoor spaces

While most are harmless, recurring webs and spider sightings can signal underlying insect activity around the home.

How Homeowners Can Help Prevent Spiders

Proactive maintenance can significantly reduce spider activity around your home:

• Declutter garages and storage areas and use sealed plastic bins
• Vacuum corners, ceilings, and storage spaces regularly
• Seal cracks and gaps around doors, windows, vents, and utility lines
• Inspect boxes, firewood, and outdoor equipment before bringing them indoors
• Trim vegetation away from structures and reduce debris near foundations

Because spiders follow their food source, controlling insects around your home is one of the most effective long-term prevention strategies.

Clark’s Expert Insight

In Central Valley homes, spider activity often points to larger pest pressure. Effective spider control focuses on reducing harborage areas, sealing entry points, and managing insects that attract spiders in the first place. A comprehensive approach helps prevent recurring problems rather than just addressing visible spiders.
