Spider Management
Black Widow Management and Spider Prevention
Interior & Exterior Barrier Treatment · Dangerous Species Focus
Most spiders in Central California are harmless and actually beneficial — they prey on the insects that would otherwise infest your home. But black widows, which are genuinely common throughout all four of our service counties, carry venom that can cause significant medical effects. Our spider program focuses on targeted management of dangerous species while reducing overall spider pressure through barrier treatment and web removal.
How We Work
Our Process
Every service follows a structured protocol designed to deliver effective, lasting results — not a temporary fix.
Inspection & Species Assessment
We inspect for black widows specifically in high-risk areas: garage interiors, crawl space access points, wood piles, under outdoor furniture, and behind storage. We note severity and locations.
Web Removal
Existing webs (including egg sacs) are physically removed with a web brush. Removing egg sacs is critical to preventing a new generation from hatching in 2–4 weeks.
Residual Treatment
Residual insecticide is applied to baseboards, corners, eave lines, garage interiors, and all identified harborage points — both contact-kill and residual effect.
Ongoing Prevention
As part of a general pest program, spider populations are maintained at low levels through regular perimeter treatment. Standalone one-time treatments are also available.
What Sets Us Apart
Why Choose 101 Exterminators
20+ years of service across four Central California counties. CA licensed, insured, and backed by a genuine satisfaction guarantee.
Dangerous Species Focus
We prioritize black widow identification and removal, particularly in garages, crawl spaces, and children's outdoor areas where contact risk is highest.
Web & Egg Sac Removal
Egg sacs hold 200–900 eggs. Physically removing them at time of treatment eliminates an entire generation before it hatches.
Combined with Pest Reduction
The best long-term spider control is reducing the insect population that spiders feed on. Our general pest programs address the root food source.

Common Questions
Frequently Asked Questions
Are black widows dangerous in California?
Yes — black widow venom (latrotoxin) can cause significant systemic effects including severe muscle pain, cramping, sweating, nausea, and in rare cases (particularly in children and the elderly) more serious complications. However, bites from California black widows are very rarely life-threatening to healthy adults. Prompt medical evaluation is recommended for any suspected black widow bite.
How do I identify a black widow?
The western black widow (Latrodectus hesperus) is shiny black, about the size of a grape, with a distinctive red hourglass marking on the underside of the abdomen. The hourglass may appear as two separate red spots rather than a complete hourglass in some individuals. Immature females and males look very different — they have yellowish or whitish markings.
Are brown recluse spiders common in California?
True brown recluse (Loxosceles reclusa) are native to the south-central United States and are rarely found in California. Most suspected "brown recluse bites" in California are from other species or other causes. The desert recluse is present in Southern California's inland areas but not common in Central California. We can help identify any spiders found during inspection.
