Wasp & Bee Removal in Daly City, CA
101 Exterminators handles wasp and bee removal in Daly City, from ground yellowjacket colonies to paper wasps built into attic vents, licensed in California under SPCB Lic. #9119. Wind off the Pacific is why nests here end up hidden — exposed eaves on the Westlake and Skyline blocks get scoured, so colonies build in wall voids, vent screens and the sheltered side instead. Honey bee swarms we move to a beekeeper when we can.
Home maintenance
How do you keep yellowjackets away from a Daly City home?
Close the vents and wall gaps they nest in, cover food outdoors, and leave honey bee swarms to a beekeeper. Daly City stays cool, with July highs averaging about 62°F, and its warmest weather comes in September and October, when yellowjacket colonies are at full size. Homes along San Bruno Mountain’s grassland and coastal scrub see the most ground nests.
Replace damaged vent screens
Wind off the ocean pushes nests into sheltered spots. Check attic, soffit and dryer vents for torn or missing screens and replace them with intact metal mesh in winter, while no colony is active.
Seal gaps in stucco and trim
Caulk cracks where trim meets stucco and around pipe and wire entries. Those openings lead into wall voids, which give wasps shelter from the wind and fog.
Fill burrows along the mountain edge
Queens start ground nests in empty rodent burrows. On lots that back onto San Bruno Mountain, fill and tamp old burrows along the fence line in spring before nests begin.
Cover food in the fall warm spell
September and October bring Daly City’s warmest afternoons and the year’s biggest colonies. Keep lids on garbage, clear plates after backyard meals, and pick up fallen fruit.
Leave nests and swarms alone
Don’t plug, spray or dig out a nest; keep people and pets back and have a professional remove it. Call a local beekeeper to collect a hanging honey bee swarm.
When to do it
Screen and seal in winter, fill burrows in spring, and keep food covered through September and October.

Warning Signs
When to Ask About Wasp & Bee Removal in Daly City
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
What to Expect from Wasp & Bee Removal in Daly City
Tell us where the nest or activity is and whether people need to pass close to it. Avoid disturbing the nest while we discuss the next step.
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
Why Choose 101 Exterminators for Wasp & Bee Removal in Daly City
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 Daly City
Why do wasps in Daly City nest inside vents instead of under the eaves?
Wind. The exposed western blocks take steady marine wind off the ocean, and an open paper wasp comb hanging under an eave does not hold up well to it. Colonies here shift to sheltered cavities — attic gable vents, soffit returns, the space behind a dryer or bathroom vent, and the underside of stair landings. That is also why the nest is often larger than expected by the time anyone notices: it was out of sight the whole time it was growing.
We back onto San Bruno Mountain and yellowjackets get bad every September. Is that normal?
It is the seasonal pattern along that whole open-space edge. Ground-nesting yellowjacket colonies build population all summer in the grassland and scrub, and by late summer and early fall the foragers have shifted toward protein and sugar and range widely to find it. The nest is frequently not on your property at all. Sealed trash enclosures and picking up fallen fruit reduce the draw; the colony itself has to be located and treated at the source.
There are honey bees going in and out of a wall on our Daly City house — can they be saved?
Sometimes, and it depends on whether they are a resting swarm or an established hive. A swarm clustered on a branch or fence is often transferable to a local beekeeper. Once bees have built comb inside a wall cavity, removal becomes structural: the comb and honey have to be taken out, because leaving them means the wax and honey draw ants, rodents and other pests into that cavity months later. We assess which situation you have before recommending anything.
