Warning Signs
Signs You Need Wasps & Bees Service in Foster 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
Our Wasps & Bees Process in Foster City
Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Foster City.
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 Foster 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.
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 Foster City
How do I know if I have yellow jackets vs. paper wasps?
Yellow jackets are stocky, bright yellow and black, and build papery nests in ground cavities, wall voids, or hollow trees. They are highly aggressive when the nest is disturbed. Paper wasps are slender with long legs and build open, umbrella-shaped comb nests (no papery cover) under eaves. Paper wasps are less aggressive and will only sting if directly handled or if the nest is disturbed.
Should I remove a wasp nest myself?
We strongly recommend against it. Yellow jacket colonies in late summer can contain 4,000–5,000 individuals and will mount a coordinated defensive sting response if disturbed. For people with known or unknown venom allergies, a single encounter can be life-threatening. Ground nests are especially hazardous because the full colony can emerge instantly.
When should I call for wasp removal vs. waiting until winter?
Most wasp colonies die off naturally in winter — only new queens survive to start new colonies in spring. If the nest is in a low-traffic area and not a safety concern, waiting until winter is a reasonable approach. If the nest is near entry doors, children's play areas, or poses a sting risk to family or pets, treatment should happen promptly regardless of season.
