Stinging Insect Control
Wasp & Bee Removal in Pleasanton, CA
101 Exterminators handles wasp and bee removal in Pleasanton — yellowjackets, paper wasps, hornets, and live relocation of reachable honey bee swarms. SPCB Lic. #9119, Alameda County. Pleasanton offers stinging insects two very different sites: the open ends of barrel tile along a Ruby Hill eave, and the dry grassland slopes below Pleasanton Ridge where yellowjackets nest underground.
Home maintenance
How do you keep yellowjackets and paper wasps away from a Pleasanton home?
Cover food outdoors, close the roof cavities paper wasps use, and leave honey bee swarms to a beekeeper. Pleasanton summer afternoons average in the mid-80s, and colonies grow through that heat. Homes along Foothill Road and below Pleasanton Ridge back onto grassland where yellowjackets nest in the ground, and tile roofs across the newer tracts give paper wasps shelter at the eaves.
Check the bird stop on tile roofs
On Ruby Hill and Laguna Oaks homes with concrete or clay tile, look along the eave for missing or broken bird stop. Have a roofer replace it in winter, while no colony is active.
Fill burrows along the grassland edge
Yellowjacket queens start nests in old rodent holes in spring. Fill and tamp abandoned burrows along the back fence and slope before nests begin, and watch any hole with steady traffic from a distance.
Cover food and fix outdoor leaks
In a dry valley summer, yellowjackets come for meat, fruit and water. Keep lids on bins, clear patio tables after meals, and fix dripping hose bibs and irrigation leaks near the house.
Leave active nests alone
Don’t spray, plug or knock down a nest. Keep children and pets away from it, mark the spot, and have a professional remove it.
Call a beekeeper for honey bee swarms
A cluster of honey bees on a branch or fence in spring is a swarm resting while scouts look for a cavity. Leave it alone and contact a local beekeeping group to collect it.
When to do it
Roof and bird-stop repairs in winter, burrow filling in March and April, and covered food from August through October.

Warning Signs
When to Ask About Wasp & Bee Removal in Pleasanton
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 Pleasanton
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 Pleasanton
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 Pleasanton
Why do wasps keep nesting under the roof tile on my Pleasanton house?
Because a tile eave is a dry, sheltered cavity with a protected entrance — the same thing a paper wasp looks for in a rock crevice. Concrete and clay tile roofs across Ruby Hill, Laguna Oaks and the Mediterranean-style tracts leave an open air space at each eave course, and unless the ends are closed with bird stop or mortar the nests come back season after season. Removing a nest solves this year. Closing the tile ends is what changes next year.
When are yellowjackets worst in Pleasanton?
August through October. Yellowjacket colonies build population all spring and summer and peak in late summer, which is when foragers switch to hunting protein and sugar and start showing up around back yard cooking, garbage cans and open drinks. Properties along Foothill Road and below the Pleasanton Ridge grassland see the most, because ground nests in old rodent burrows sit right at the property line. A nest found in May is far smaller than the same nest in September.
Can a honey bee swarm in my Pleasanton back yard be saved instead of killed?
Often yes, if it is a swarm hanging in the open on a branch or fence and has not yet moved into a wall. Swarms are the most transferable stage, and we can arrange a handoff to a local beekeeper rather than treating them. Once bees have moved into a wall void, a chimney chase or a soffit and built comb, the situation changes — that comb and honey have to come out along with the colony, or the residue draws ants, cockroaches and beetles into the same cavity.
