Spider Management
Spider Control in Burlingame, CA
101 Exterminators provides spider control in Burlingame with the focus where it belongs — western black widows (Latrodectus hesperus) in garages, crawl spaces and storage — under SPCB Lic. #9119, working since 2005. Most spiders here are harmless and eat the insects you would otherwise be calling us about. The detached garages behind century-old Easton Addition lots are the exception. We treat harborage and pull the webs and egg sacs.
Warning Signs
Signs You Need Spiders Service in Burlingame
Interior and exterior spider control treatment targeting known harboring locations — especially dark corners, eave lines, garage interiors, wood storage areas, and crawl spaces. We include physical web removal as part of the service to eliminate existing egg sacs and reduce harborage. Treatment uses residual insecticide applied directly to spider runways and harbor areas rather than broadcast spraying.
Black widow webs — irregular, messy, strong silk webs in dark corners and under objects
Visible black widow — glossy black body with red hourglass marking on underside of abdomen
Webs with egg sacs — round, papery sacs in the web often indicate established nesting
Spider activity in garages, crawl spaces, or outdoor storage areas
High general spider population inside or outside — indicates abundant insect prey for them
Bites of unknown origin — if black widow bite is suspected, seek medical evaluation promptly
How It Works
Our Spiders Process in Burlingame
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Burlingame.
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.
Why 101 Exterminators
Spiders You Can Count On in Burlingame
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
Spider Control FAQs for Burlingame
Are black widows common in Burlingame garages?
Yes — the detached garage is the single most common place we find them in this city. Widows want dark, dry, undisturbed spots close to the ground, and the older Burlingame lots with a separate garage set back from the house provide that along with stored boxes, lumber and equipment nobody moves. Check the low corners, behind stacked items and along the sill plate with a flashlight. Gloves and a cleared floor do more for you than any spray does.
Is there a brown recluse risk in Burlingame?
No — brown recluse spiders are not established in San Mateo County or in coastal California at all. The spiders most often mistaken for them here are harmless funnel weavers and male house spiders, which move fast and get noticed at night. The genuinely significant one in Burlingame is the western black widow (Latrodectus hesperus): glossy black, red hourglass underneath, sitting still in a messy low web. Photograph or capture the spider and we can identify it for you.
Do spiders get worse in Burlingame during the rainy season?
You see more of them indoors then, even though the outdoor population has not spiked. When rain saturates the ground between November and March, spiders and the insects they hunt move into garages, crawl spaces and sheds for dry harborage, so the sightings jump. Sealing the garage door sweep, screening the crawl-space vents and closing gaps at utility penetrations cuts it down. Knocking webs out regularly helps too — a spider that cannot hold a web in a spot moves on.
