Identify, prevent, and control the spiders common to San Diego homes and businesses — with low-pesticide, professional methods.
Call (619) 421 - 2101Spiders are among the most common — and most misunderstood — pests in San Diego homes and businesses. The vast majority are harmless and actually beneficial, quietly preying on the insects you would rather not have around. This Integrated Pest Management (IPM) plan focuses on identifying the spiders you are likely to encounter, keeping them out through prevention and habitat changes, and reserving pesticides for a judicious last resort.
Only one local species — the western black widow — is of real medical concern. Everything else comes down to reducing clutter, sealing entry points, and cutting off the insect prey that draws spiders indoors.

The classic indoor cobweb spider. Shy and non-aggressive, it builds tangled webs and rarely bothers people.
Often mistaken for a "daddy long-legs." Delicate and completely harmless, it prefers cool, damp corners.
San Diego's one spider of real medical concern. It is not aggressive, but its bite warrants prompt medical attention.
The only recluse native to Southern California. It lives in desert foothills and is very rarely found inside urban San Diego homes.
The large web-spinner you meet on autumn mornings. A valuable outdoor predator that thins out flying insects.
Small, curious, and quick. It hunts by sight rather than webs and poses no threat to people.
This gray wall jumper is a perfect example — a harmless, sharp-eyed hunter that spends its day eating the flies, ants, and mosquitoes you would rather not share your home with. IPM works with that natural balance instead of against it, targeting only the spiders that pose a genuine problem.
How GC Termite Control manages spiders — from monitoring through a judicious chemical last resort.
Every plan starts with knowing what you actually have. A technician inspects the spots spiders favor and identifies the species involved.
The single most effective, longest-lasting step is denying spiders a way in and a place to settle.
Spiders follow their food. Making the property less attractive to insects makes it less attractive to spiders.
Outdoors, a healthy yard keeps spider prey in balance on its own.
Direct removal is fast, chemical-free, and often all a light infestation needs.
When populations persist or a black widow is established near living areas, treatment is targeted and judicious — never blanket spraying.
Simple, effective steps that make your property far less inviting to spiders.
Seal exterior cracks, gaps, and utility penetrations
Install door sweeps and repair torn window screens
Declutter garages, closets, and storage areas
Move woodpiles, bricks, and stone away from the house
Sweep away webs and egg sacs as soon as they appear
Switch exterior bulbs to yellow "bug lights" to draw fewer insects
Reduce indoor humidity in basements and crawl spaces
Wear gloves when reaching into dark, undisturbed storage
GC Termite Control will identify what you are dealing with and put together an integrated plan tailored to your property — including safe handling of black widows.
No. The brown recluse (Loxosceles reclusa) is not established in California. The only recluse native to our region is the desert recluse (Loxosceles deserta), which lives in desert foothills and is very rarely found inside urban San Diego homes. Most suspected "recluse bites" here turn out to be something else entirely.
The vast majority of San Diego house spiders are harmless and even beneficial. The one to respect is the western black widow, whose bite is medically significant. It is not aggressive, but if you are bitten and develop severe pain, cramping, or other symptoms, seek medical care promptly.
Seal cracks and gaps, add door sweeps and screens, and reduce clutter and outdoor harborage like woodpiles and debris. Then cut off the insect prey that draws them in by managing exterior lighting and moisture. Knocking down webs and egg sacs as they appear keeps populations from building.
For a handful of harmless spiders, prevention and regular cleaning usually do the job. Call a professional when you have recurring infestations, egg sacs you cannot get ahead of, or a venomous species such as the black widow near living areas. GC Termite Control offers a free review and estimate.
