The nest you can see is treated first. The nests you cannot see -- inside the soffit, in the ground near the foundation, in the hollow tree 20 feet away -- are found during our property sweep and treated the same visit. That is the difference.
Full sweep, correct sequence, residual prevention -- the complete wasp elimination protocol.
Most wasp problems are multi-nest situations. Treating only the visible one leaves the secondary nests intact. We check all potential nesting sites on the first visit -- not because something went wrong, but because that is how the job is done correctly.
Different nests require different protective approaches. A paper wasp nest under an eave is a low-to-moderate threat. A yellow jacket ground nest at your kids' play structure with 3,000+ workers is a different situation entirely. We match the protective protocol to the threat level.
When wasps are nesting inside a wall or attic, the entry point spray approach leaves the vast majority of the colony untreated. We access the void -- through the interior if necessary -- inject the correct product directly into the nest chamber, and seal the entry after the colony has been eliminated.
After treatment, every former nesting site receives a residual application specifically formulated to deter new nest establishment. Wasps that survived or return from foraging cannot start a new colony at a treated location that carries an effective residual barrier.
Paper wasps in Atherton, CA are the species most frequently called about but least likely to represent a genuine safety emergency. Their open-comb nests under eaves and window frames are easily visible and often alarming in appearance, but the colony is relatively small and the wasps do not attack unless directly provoked. The key distinction from yellow jackets is the open hexagonal comb -- paper wasps do not enclose the nest in a paper envelope. A paper wasp nest that is not near a high-traffic area can often be monitored rather than immediately treated, but one near a door, a play structure, or a walkway where physical contact is possible should be removed professionally. The colony dies naturally in fall, but the nesting location should be treated with residual product to prevent re-establishment next season by a new queen.
The behavioral profile of yellow jackets -- as opposed to paper wasps -- is the reason void nests and ground nests require professional treatment. A yellow jacket colony does not tolerate intrusion. The defensive response is proportional to colony size: a small early-season colony of a few hundred workers produces a manageable defense, while a late-summer colony of 4,000 or more produces a simultaneous attack by dozens of workers that can result in multiple stings before a person can retreat. DIY knockdown spray aimed at the entrance of a ground nest stimulates the colony's defensive response without delivering enough active ingredient to the interior to eliminate the population -- the result is an agitated colony that is now aware of a threat at its entrance, with hundreds of workers mobilized in defense and an undamaged nest interior.
Identifying a bald-faced hornet nest versus other paper nests is important because the treatment protocol -- and the safety profile for the person attempting treatment -- is significantly different. The enclosed gray paper envelope is the key visual identifier. Bald-faced hornets will exit the nest and pursue a threat at distances that paper wasps will not. Do not approach the nest within 10 to 15 feet without protective equipment. If the nest is in a tree near an active area of the yard, near an entrance, or in a location where children or pets will be nearby, same-day service is appropriate.

The most problematic wasp situation from a DIY treatment standpoint is the void nest -- a yellow jacket colony established inside a wall void, soffit cavity, or attic space. Void nests are identified by a consistent entry point through a gap, crack, or opening in the exterior of the structure -- typically a wood joint, a gap in vinyl siding, or an opening around a pipe or conduit penetration. The number of workers entering and exiting the entry point is a reliable indicator of colony size and maturity. A large void nest may have a substantial buzzing sound audible from inside the adjacent room. Spraying the exterior entry point with consumer knockdown spray addresses only the guards at the entrance -- it does not reach the nest chamber inside the void, and it agitates the colony while leaving the population intact. The workers inside increase their defense activity, and the colony may begin exiting through secondary entry points deeper in the structure. The correct approach is void injection -- applying insecticide directly into the nest chamber through a small access point -- followed by sealing the primary entry after the colony is eliminated.
Fall is the appropriate window for preventive treatment at high-risk nesting sites -- eave boards where repeated nesting has occurred, attic gable vents with a history of yellow jacket activity, and ground nest entrance areas from the current season. Queens that mated in late summer overwinter in sheltered sites and re-establish nests in spring, showing strong fidelity to previous nesting locations. A residual product applied to former nesting sites in late fall -- after the colony has died or been eliminated -- deters new queen establishment in spring when queens begin scouting for nesting locations. This preventive application is especially effective for properties that deal with recurring annual nest establishment at the same location, which is a consistent pattern when the post-season residual is not applied. The cost of preventive fall treatment is a fraction of the cost of reactive season treatment.
Same-day response for active wasp and hornet nests in Atherton. Call and we confirm arrival before you hang up.
Call +1-866-315-0243Same-day dispatch for active nests. Scheduled visits for preventive treatment.
We sweep the full property before treating any individual nest -- all eave lines, soffits, gable ends, tree branches, ground areas, wood pile edges, and landscape features. Secondary nests are found and treated the same visit.
Treatment includes removal and the residual application that prevents next-season re-establishment at the same site.
Ground nest treatment with full protective gear, correct product application to the nest interior, and entrance sealing to prevent reuse.
Gray enclosed paper nest treatment with maximum application distance and full protective equipment. Bald-faced hornets are highly aggressive near the nest -- safe treatment requires distance and protocol that consumer products cannot provide safely.
Void injection, entry sealing, and structural assessment -- the complete protocol for wall and attic yellow jacket colonies.
Fall application of residual insecticide to prior nesting sites -- eave boards, gable vent edges, former ground nest entrances, and soffit gaps -- to prevent spring queen establishment at the same location.
Threat assessed, all nests located, treated in correct sequence, residual applied.
Phone assessment establishes the nest type and urgency. We confirm dispatch before you hang up.
Every technician arrives equipped for all nest types. The equipment appropriate to the specific situation is already on the vehicle.
Every potential nesting site on the property is checked before treatment begins -- all eave lines, ground areas, tree structures, and exterior openings. Secondary nests are documented and included in the treatment plan.
Nests treated in the correct sequence based on threat level and location. Ground nests last (highest defensive response). Aerial and void nests treated with species-appropriate protocol. Residual applied to all former nesting sites after elimination.
Three situations -- including a bald-faced hornet nest DIY attempt and a void nest a previous contractor missed.
I found the ground nest when I was nearly on top of it. Called Show Me Pest Control immediately. Same-day service on a Sunday. Technician found two additional nests during the sweep. Every nest treated. No stings at pickup the next day.
Attempted to spray what I thought was a wasp nest. Got stung 11 times before I got back inside. Show Me Pest Control identified it as bald-faced hornets -- a completely different threat level than I understood. Treated correctly. Inactive within 15 minutes. I had no idea there was such a difference between nest types until this happened.
Customers were getting stung at the front entrance of my business from a nest nobody could find. A previous contractor sprayed the outside of the soffit repeatedly with no result. Show Me Pest Control accessed the void from the attic, identified the nest in the cavity, treated directly, and sealed the entry. Zero customer stings the following season.
