Wasp & Bee Removal in San Leandro, CA
101 Exterminators handles wasp and bee removal in San Leandro — yellowjackets in the ground and in wall voids, paper wasps under eaves, honey bee colonies established inside structures. California licensed, SPCB Lic. #9119, working Alameda County since 2005. The dry slopes below Anthony Chabot Regional Park on the city's east edge are yellowjacket ground, and the wide 1950s eaves on the tract streets below them are paper wasp ground.
Warning Signs
Signs You Need Wasps & Bees Service in San Leandro
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 San Leandro
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in San Leandro.
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 San Leandro
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.
Same-Day Service for Emergencies
A wasp nest near an entry door, child's play area, or pet run is a safety emergency. We prioritize same-day or next-day service for these situations.
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 San Leandro
There is a yellowjacket nest in the ground on my Bay-O-Vista slope — is it safe to leave alone?
A ground nest well away from foot traffic can sometimes be left until the colony dies out over winter, but not one near a path, a play area or a door. Yellowjacket colonies on the San Leandro hillsides peak in late summer and defend the entrance hard when a mower, a hose or a footstep disturbs it. Anyone in the household with a venom allergy takes the question off the table. Mark the entrance from a distance and call — do not seal it, because they will chew a new exit through the void.
Wasps rebuild under the eaves of my Washington Manor house every spring — why there?
That eave is close to a perfect paper wasp site, and the post-war tracts are full of them. Polistes wasps want a flat, sheltered overhang out of the wind and rain, and the wide overhangs, low-pitch roofs and recessed entryways of San Leandro 1950s housing give them exactly that. They also return to locations that worked before. Removing combs during the season and checking the eave line early each spring is what breaks the pattern.
We have bees going into a wall of our San Leandro house — can they just be sprayed?
Not without creating a second problem. An established honey bee colony inside a wall holds comb and stored honey, and killing the bees while leaving the comb behind lets that honey melt into the wall cavity — staining, odor, and months of ants and other insects working the residue. The right sequence is opening the cavity, removing the comb and sealing the entry point. If it is a swarm clustered on a limb rather than an established colony, a beekeeper can often take it instead.
