Wasp Nest on Your Property? We Remove It Safely.
Wasp and yellow jacket activity in Los Angeles peaks in late summer and fall when colonies are at maximum size and most aggressive. A nest near a doorway, playground, or outdoor dining area is a genuine sting risk. We remove it completely.

Signs You Have a Problem
- A visible paper nest — gray, layered, and football- to basketball-sized — attached to eaves, under deck ledges, inside BBQ grills, in attic vents, or in dense shrubs
- Consistent wasp traffic entering and exiting a specific point in the ground, a wall void, or a structural gap — yellow jackets frequently nest underground or inside wall cavities and are identified by the steady stream of workers entering the opening
- Mud tube structures on walls, under eaves, or on outdoor furniture — mud daubers (Sceliphron species) build individual mud chambers for egg-laying and are largely non-aggressive but indicate active wasp presence
- Increased wasp activity near food at outdoor gatherings — yellow jackets are strongly attracted to protein foods and sweet drinks in late summer and fall as their colony's need for protein increases
- Multiple wasp stings to people or pets in a specific area of the yard without a visible nest — the nest may be underground, in a dense hedge, or in a structure void that is not immediately apparent
- Wasps entering the interior of the home through gaps around windows, doors, or vents — late fall yellow jacket workers sometimes enter structures looking for overwintering sites
Our Treatment Process
- 1
Species and Nest Location Assessment
Paper wasps (Polistes species), yellow jackets (Vespula and Dolichovespula species), bald-faced hornets, and mud daubers each require a different removal approach. Paper wasp nests are open-faced and accessible. Yellow jacket nests are frequently concealed in ground burrows or wall voids. Bald-faced hornet nests are enclosed and large. We assess the species, nest location, and size before selecting a removal method.

Protective Equipment and Timing
Wasp removal work requires full protective equipment. We schedule wasp jobs for early morning or evening when most foraging workers are inside the nest and the colony is least active. Attempting nest removal at mid-day when foragers are fully active and defensive is the most common cause of sting incidents during DIY attempts.

Nest Treatment
We apply an appropriate insecticide directly into or onto the nest — residual dust into ground openings and wall voids for yellow jackets, aerosol pyrethroid for accessible paper wasp and hornet nests. Treatment is applied in a single rapid application to prevent alarming the colony before the product takes effect. For wall void nests, we may need to create a small access point to treat the nest interior.

Nest Removal
Once the colony is eliminated, we physically remove the nest structure. For ground nests and wall voids, we remove the comb and colony material and seal the entry point. Leaving a dead nest in place — particularly a yellow jacket nest inside a wall void — creates conditions for secondary pests (beetles, moths) and the residual pheromones attract new queens looking for nesting sites the following season.
- 5
Prevention Assessment
We inspect for conditions that attract nesting wasps — open eave voids, unsealed wall gaps, soil conditions conducive to ground nesting, and accessible food sources. We provide recommendations for preventing nest establishment in future seasons.
How to Prepare for Treatment
- Do not disturb the nest or attempt to spray it with over-the-counter products before our arrival — agitated yellow jackets and paper wasps release alarm pheromones that recruit other colony members to sting
- Keep children, pets, and non-essential people away from the nest area and well inside the home during our removal work
- If the nest is near an exterior door, use an alternate entrance to your home until after removal to avoid disturbing foraging workers
- If anyone in your household has a known venom allergy, ensure they are inside with their epinephrine auto-injector available before our work begins
- Mark the nest location or entry point clearly if it is not immediately visible so our technician can locate it on arrival without approaching too closely before suited up
After Treatment: What to Expect
- Expect some wasp activity near the former nest site for 24–48 hours after treatment as foraging workers that were away from the nest return and find the colony eliminated
- Seal the entry point of any wall void or eave gap where a yellow jacket nest was located to prevent future queens from selecting the same cavity as a nesting site
- Remove any exposed food waste, open compost, and standing protein food sources from outdoor areas — yellow jackets are primarily driven to human areas by food availability
- Inspect eave voids, soffit gaps, and ground areas for new nest starts in early spring before colonies develop to a defensive size — small nests detected early are far easier to treat than mature colonies
- If you see renewed wasp activity at the treatment site within 2 weeks, contact us — some yellow jacket wall void treatments require a follow-up to address colony members that relocated within the wall
Wasp & Hornet Control — Frequently Asked Questions
Paper wasps (Polistes species) are the slim, long-legged wasps that build open, umbrella-shaped nests under eaves and are relatively docile unless directly disturbed. Yellow jackets (Vespula species) are stocky, aggressive wasps that frequently nest underground or in wall voids and are the most common sting-incident species in LA. Bald-faced hornets build the large, enclosed gray paper nests and are highly defensive within 15–20 feet of their nest. All three species are present in Los Angeles, with paper wasps and yellow jackets being most common.
Yellow jacket colonies reach their maximum population size in August through October in the Los Angeles climate. At peak colony size, food demand for developing larvae is highest, driving forager workers to aggressively pursue protein food sources. Simultaneously, the colony becomes more defensive as it protects large stores of comb and brood. The combination of peak numbers, food competition, and heightened defensiveness makes late summer and fall the highest-risk period for sting incidents.
Small paper wasp nests (fewer than 10 cells, no workers present) can sometimes be knocked down at night with protective covering. Any nest with active workers — particularly yellow jackets in a wall void or ground nest — is genuinely dangerous without proper protective equipment and knowledge of the species' defensive behavior. Yellow jacket stings cause more deaths annually in the US than any other venomous animal. We do not recommend DIY removal of any established colony.
Yellow jacket and paper wasp colonies die off entirely each winter in most climates, but in Los Angeles' mild climate, some yellow jacket queens successfully overwinter and can re-establish nests in the same location the following spring. Leaving a treated nest in place without sealing the entry point significantly increases the probability of a new colony establishing in the same void. We always recommend sealing entry points after nest removal.
