Wasp & Bee Removal in Los Altos Hills, CA

101 Exterminators handles wasp and bee removal in Los Altos Hills — yellowjacket nests in the ground, paper wasps under barn eaves, hornets, and honey bee colonies inside wall voids. CA licensed under SPCB Lic. #9119, working Santa Clara County since 2005. Where properties run an acre with stables, arenas and vineyard rows, one household often has three different nesting situations at the same time.

Local Context

Barns, Arenas and Vineyard Rows Give Yellowjackets Three Kinds of Nest Site

Yellowjacket pressure peaks in late summer, roughly August through October, when colonies reach full population and foragers hunt protein and sugar aggressively. In Los Altos Hills that lands squarely on the grape harvest. Enough residents here have put in vineyard rows that fruit is ripening across town in exactly those weeks, and split or dropped grapes are a sugar source that pulls foragers into the places people stand and work.

The ground supplies the second kind of nest. Yellowjackets take over abandoned rodent burrows, and on properties where Botta's pocket gopher (Thomomys bottae) works irrigated pasture and orchard soil, abandoned burrows are everywhere. That is how an in-ground nest turns up in the middle of a lawn or a paddock on a Purissima Road property with no structure anywhere near it.

Structures give the third. Barn and stable eaves, riding arena trusses, open carports, pool cabanas, pump houses and the deep overhangs on Modern Ranch houses are all open-comb paper wasp habitat, and wall voids and chimney chases along Moody Road and Fremont Road pick up honey bee colonies each spring. Backing onto Byrne Preserve and the Rancho San Antonio frontage means swarms keep arriving from habitat nobody treats.

How We Work in Los Altos Hills

We identify the species first, because a honey bee colony and a yellowjacket nest are different jobs with different endings. In Los Altos Hills the survey covers barn and arena eaves, carport ceilings, pump houses, pool cabanas, and ground openings out in pasture where gopher burrows have been taken over. In-ground nests are treated in the evening once foragers are back. Technicians work in full protective equipment, remove accessible nests, and seal the cavity so a new colony does not claim the same hole. Accessible honey bee swarms we try to place with a local beekeeper.

Los Altos Hills Climate

The foothill elevation gives Los Altos Hills 18 to 24 inches of rain a year, more than the valley floor below it, and the oak woodland keeps ground-level humidity up under the canopy even when open areas hit 85 to 93°F in July. The number that drives pest behavior here is not the temperature, it is the contrast that opens in summer. The creeks draw down or run dry by July while the town's landscaping, pastures, and leach fields stay wet on a schedule. From midsummer through the first rains, the irrigated parcels are the only reliably damp ground for a long way, and gophers, rats, and wildlife all move toward them.

Housing Stock

The town is almost entirely custom single-family homes on lots of an acre and up, running from 1950s and 1960s ranches through recent large builds, with working horse properties, stables, and remnant orchard trees mixed among them. That layout matters for pests in a couple of ways. Many parcels are on septic rather than sewer, and a leach field holds a defined patch of subsoil moist straight through a dry summer, which is what gophers and subterranean termites are both looking for. And the outbuildings add up: a barn, a hay store, a tack room, a pool house, a detached garage, a well house. Each one is unheated wood that nobody walks through daily, which is where black widow and rodent populations get established before anyone notices them.

Why Local Expertise Matters

A gopher program on a two-acre horse property is a different job from a gopher program on a suburban lot, and treating them the same is why the mounds come back. Here we map the active tunnel systems across the whole parcel, work the main runs instead of the surface mounds, and set the schedule around irrigation and pasture use rather than a fixed calendar. On septic parcels we locate the leach field and the well head before anything else, because those areas change both where the activity concentrates and where we are willing to work. That calibration comes from doing agricultural and rural properties across our four counties since 2005. SPCB Lic. #9119.

Warning Signs

Signs You Need Wasps & Bees Service in Los Altos Hills

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 Los Altos Hills

Every job follows the same methodical approach — no shortcuts, no guesswork. Here is what to expect when you work with us in Los Altos Hills.

01

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.

02

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.

03

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.

04

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 Los Altos Hills

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 Los Altos Hills

Yellowjackets swarm our vineyard rows at harvest. Can anything be done?

Yes — the work is nest location and structure protection, not spraying fruit. Yellowjacket colonies peak from August through October, exactly when Los Altos Hills estate vineyards ripen, and foragers come for the sugar in split and dropped grapes. We find and treat the in-ground and void nests within range of the rows, and advise on clearing dropped fruit and covering waste containers. We do not treat fruit you intend to harvest.

There is a wasp nest in the rafters over my horse stall. Is treatment safe around animals?

It can be, with placement and timing planned around the animals. We move horses out of the immediate area for the treatment and the re-entry interval, treat and physically remove the nest rather than leaving material above feed and water, and keep application off open bins and troughs. Tell the technician which stalls are occupied and where the water lines run. Barn eaves and arena trusses are among the most common paper wasp sites we work in Los Altos Hills.

A honey bee swarm landed in an oak on our Moody Road property. Do you kill it?

Not if it can be relocated. A swarm resting in a tree is usually a temporary cluster looking for a permanent cavity, and when it is accessible we try to arrange transfer to a local beekeeper rather than treating it. The situation changes once bees establish inside a wall void or chimney chase, where comb, honey and larval material have to be removed to prevent odor and secondary pests. Call while the cluster is still in the tree — that is the easiest stage to work with.

Local Pest Pressure

Common Pests We Treat in Los Altos Hills

Every area has its own pest profile shaped by climate, housing, and geography. These are the pests we see and treat most often in Los Altos Hills — tap any one to learn how to identify it and what treatment involves.

Pocket Gophers

Large irrigated lots, horse pastures, and orchard soil throughout Los Altos Hills create the most extensive gopher habitat in Santa Clara County — nearly every property has gopher activity

Roof Rats

Orchard trees throughout the large lots and the oak woodland canopy of the hillside provide endemic roof rat habitat with direct roofline access from overhanging branches

Wildlife Intrusion

Open space adjacency from Rancho San Antonio and the foothills brings gray squirrels, raccoons, and other wildlife that enters attics and crawl spaces more commonly than in flat valley cities

Drywood Termites

Custom homes throughout Los Altos Hills from the 1950s–1980s have original wood framing with established drywood termite histories

Black Widows

Horse stables, hay storage, tool sheds, and the abundant outdoor structures throughout large-lot Los Altos Hills properties are prime black widow habitat
