Wasp & Bee Removal in Sunnyvale, CA
101 Exterminators handles wasp and bee removal in Sunnyvale — yellow jacket nests in the ground and in wall voids, paper wasp combs under eaves, and live relocation of honey bee swarms wherever the situation allows. California licensed, SPCB Lic. #9119, since 2005. Sunnyvale's low-pitched ranch overhangs and shallow Eichler soffits hand paper wasps a sheltered ledge within reach of nearly every front door in town.
Warning Signs
Signs You Need Wasps & Bees Service in Sunnyvale
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 Sunnyvale
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Sunnyvale.
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 Sunnyvale
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 Sunnyvale
Why are there so many paper wasp nests under Sunnyvale eaves?
Because the housing gives them the ledge they look for. Post-war Sunnyvale ranches have wide, low-pitched eaves and the Eichler tracts have nearly flat roof lines with exposed beam soffits — both are flat, shaded and sheltered, which is exactly what a founding queen wants in spring. Patio covers and recessed entries add more of the same. Knocking a comb down without treating it usually means the same queen rebuilds within a few feet.
When do yellow jackets turn aggressive in Sunnyvale?
Late August through September, once colonies peak and workers switch from hunting insects to scavenging protein and sugar. That is when they show up at outdoor tables on South Murphy Avenue and around the picnic areas at Baylands Park and Las Palmas Park. The nest itself is usually underground nearby — an old rodent burrow, an irrigation box, a void under a shed. Finding the entry hole matters far more than treating the ones circling your table.
Honey bees are going into a wall of my Sunnyvale house — can they be relocated?
A swarm hanging in the open can often be transferred to a local beekeeper. A colony that has already moved into a wall, chimney or roof cavity is a different job: the comb has to be opened up and removed along with the bees, because abandoned honey melts into the wall and pulls in ants, rodents and other insects afterward. Spring is when swarms move through Sunnyvale, and the sooner you call after you see bees entering a gap, the less comb there is to deal with.
