Wasp & Bee Removal in South San Francisco, CA
101 Exterminators handles wasp and bee removal in South San Francisco, from yellowjacket ground nests to honey bee colonies inside a wall, California licensed under SPCB Lic. #9119 since 2005. The coastal scrub on San Bruno Mountain runs right up to the back fences at Paradise Valley and Terrabay, and that ground supplies the yellowjackets that turn up in yards below it every August. Identification comes before anyone touches a nest.
Warning Signs
Signs You Need Wasps & Bees Service in South San Francisco
We treat yellow jacket nests (including in-ground and wall-void nests), paper wasp nests under eaves and overhangs, European and bald-faced hornet nests, and mud dauber tubes. For honey bee hives established in walls or structures, we provide complete treatment and nest removal including comb excavation to prevent future odor and secondary pest attraction. For accessible swarms, we can arrange transfer to a local beekeeper.
Visible nest under eaves, in shrubs, attached to window frames, in tree cavities, or in attic vents
Repeated wasp activity near a specific location on the structure — nest is likely nearby
Wasp or bee activity around a specific gap, crack, or vent opening — indicates cavity nest inside
In-ground yellow jacket activity — small hole in soil or mulch bed with wasps entering and exiting
Honey bee swarm visible on a tree, shrub, or structure — usually a temporary cluster
Buzzing sounds within walls, soffits, or chimney area — established honey bee hive
How It Works
Our Wasps & Bees Process in South San Francisco
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in South San Francisco.
Species & Nest Location
We identify the species and locate all nesting sites, including in-wall or structural voids that require special access. Species determines the treatment approach.
Treatment in Protective Equipment
Our technicians treat nests in full protective equipment — veil, suit, and gloves. Evening treatment is preferred for ground nests when foragers have returned to the nest.
Nest Removal
After treatment, accessible nests are physically removed. For wall-void nests, we advise on comb removal to prevent secondary pest attraction from wax, honey, and larval material.
Entry Point Sealing
We seal entry points used by cavity-nesting species to prevent re-colonization by a new colony in the same location.
Why 101 Exterminators
Wasps & Bees You Can Count On in South San Francisco
Bee Relocation Option
When possible, we work with local beekeepers to relocate honey bee swarms and accessible hives rather than exterminating them. Good for bees, good for local agriculture.
Wall-Void Nest Removal
Nests inside walls require more than just treatment — the comb must be removed to prevent honey seepage, secondary pests, and odor. We handle the complete remediation.
Urgent Situations Come First
A wasp nest near an entry door, child's play area, or pet run is a safety emergency. We move these ahead of routine work.
Evening Ground Nest Treatment
Yellow jacket ground nests are treated at dusk when the full colony has returned, maximizing effectiveness and minimizing any risk of disrupted forager activity.
Common Questions
Wasp & Bee Removal FAQs for South San Francisco
We found a yellowjacket nest in the ground behind our Terrabay house — what now?
Back away, mark the spot from a distance, and keep people and dogs off that part of the yard until it is treated. Ground nests on the San Bruno Mountain slope usually sit in an old rodent burrow with one small opening, which is why they get hit with a mower or a string trimmer before anyone sees them. A disturbed colony defends the entrance in numbers and yellowjackets can sting repeatedly. Evening treatment, with the whole colony back inside, is what works.
Are the insects under our roof tile in South San Francisco honey bees or yellowjackets?
Watch the traffic before you decide. Yellowjackets fly a fast, direct line, look bare and are sharply banded; honey bees are fuzzier, fly more slowly and often arrive with pollen visible on their legs. Both will use the same air gap under roof tile or behind a stucco soffit, so the location tells you nothing on its own. We confirm the species first, because honey bees may be relocated and the comb has to come out either way.
When are wasps worst in South San Francisco?
Late summer into early fall. Colonies reach peak size after the long dry stretch, and this city gets its warmest, clearest weather at the tail end of summer, so activity holds later than most people expect. Foraging also shifts toward protein and sugar then, which is why they show up at backyard tables and picnic areas around Orange Memorial Park in August and September. Keep food covered and lids seated on outdoor bins through that window.
