Spider Control in Burlingame, CA
101 Exterminators provides spider control in Burlingame with the focus where it belongs, on 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
Treatment starts with the harborage rather than the room. We work through garages, crawl spaces, sheds, wood storage, eave lines, patio furniture, and the meter and hose bib boxes that nobody opens, and we place product on the runways and voids where widows sit instead of broadcasting it across open floors. Webs and egg sacs come down by hand with a web brush, because a residual product does very little to the eggs inside a sealed sac. When the spider count is high across a whole property, the honest answer is usually the insect population feeding them, so we also look at exterior lighting, stored debris, and the ant or fly pressure driving the food supply.
Messy, irregular webs with unusually strong silk in garage corners, under benches, and behind stored boxes
A glossy black spider hanging belly-up in its web, with a red hourglass on the underside of the abdomen
Papery, spherical egg sacs about half an inch across suspended in the web
Cast skins and insect husks piling up under a web that stays in one spot for weeks
Spiders showing up indoors with the first rains of late fall
Heavy web buildup along eaves and porch lights, which points at an insect food supply more than a spider problem
A bite followed by worsening muscle pain or cramping, which calls for prompt medical evaluation
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 Identification
We check the places widows favor first: garage corners and door tracks, the underside of patio furniture, wood piles, crawl space piers, utility boxes, and the gap behind shutters and wall fixtures. We identify what we find instead of treating every spider as a widow, since cellar spiders and orb weavers are common here and neither calls for the same response.
Web & Egg Sac Removal
Webs and egg sacs are brushed out by hand. A widow sac is a papery sphere roughly half an inch across, and the eggs inside are shielded from any surface product, so physical removal is the only part of the visit that deals with the next generation.
Targeted Harborage Treatment
Residual product goes on the surfaces widows cross: the backs of garage corners, sill plates, the underside of ledges and furniture, void openings, and the exterior band where wall meets soil. Placing it there uses less product than a broadcast spray and keeps it dry, which is what makes a residual last.
Conditions & Ongoing Prevention
We tell you which conditions on the property are doing the recruiting, whether that is wood stacked against siding, cardboard on a garage floor, an unscreened crawl vent, or a bright porch light pulling insects in all night. Properties that back onto open space usually do better on ongoing perimeter service, and single visits are available for one problem area.
Why 101 Exterminators
Spiders You Can Count On in Burlingame
Widow-First Inspection
We prioritize the places people reach into without looking: garage shelving, wood piles, patio furniture, crawl space access hatches, and outdoor storage in yards where children play.
Egg Sacs Removed by Hand
Surface product does not reach the eggs sealed inside a sac. Brushing sacs out during the visit takes that generation out of the count before it disperses across the property.
Targeted, Not Broadcast
Product goes on runways, voids, and harborage rather than open floors and lawns. That is better placement for reaching a spider and it puts less product in the space your family uses.
The Food Supply Gets Addressed
Spiders follow insects. A general pest program that holds ants, flies, and moths down is the part of spider control that keeps working between visits.
Common Questions
Spider Control FAQs for Burlingame
Are black widows common in Burlingame garages?
Yes, and 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, because 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, since a spider that cannot hold a web in a spot moves on.
