Treating one nest and calling it done is how a wasp problem comes back in three weeks. Our technicians in Chelan inspect the full property for all nest types -- including the ones inside walls, in the ground, and in trees the customer never noticed.
The nest you know about and the ones you do not are all treated in the same visit.
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.
Yellow jackets nesting inside a wall void, soffit cavity, or attic space cannot be eliminated by spraying the exterior entry point. The nest is accessed through the cavity, and the entry point is sealed after treatment. This requires different equipment and a different approach than aerial or ground nest treatment.
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 are the most common stinging insect encountered by homeowners in Chelan, WA. They build open, umbrella-shaped combs -- visible hexagonal cells without a paper envelope surrounding them -- typically under eaves, in window frames, inside porch ceilings, and along fence tops. Paper wasps are not aggressive by nature and will not attack unless the nest is directly handled, struck, or approached to within about 12 inches. A single paper wasp colony typically contains 20 to 100 workers and dies off naturally as temperatures drop in fall, with the colony queen overwintering in protected sites. The nest will not be reused the following spring -- but a new queen may establish a new nest in the same location. Most homeowners significantly over-react to paper wasp nests and would benefit from understanding that a nest in a low-traffic location poses minimal risk. The real concern is a nest directly over a doorway, at a play area, or in a location where people regularly pass within arm's reach.
Yellow jackets are what most people mean when they say wasps, and they are the species responsible for the majority of serious stinging incidents. Their nesting behavior ranges from ground nests -- holes in soil or under landscape features -- to void nests inside walls, soffits, and attic spaces. Ground nests are particularly dangerous because the entrance is often concealed at ground level and the defensive zone surrounding the entrance is large. A person mowing a lawn, a child playing in the yard, or an adult working near a landscape bed may not see the nest entrance before they enter the defensive perimeter. Yellow jacket stings are painful, multiple, and can produce serious allergic reactions in sensitized individuals.
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.

Void nests are confirmed by the pattern of worker entry and exit through a single gap in the exterior structure. Unlike aerial nests or ground nests, the nest body is completely invisible from outside. The danger of the entry-point-spray approach is not just ineffectiveness -- it can cause the colony to establish secondary exits deeper in the wall, meaning workers begin exiting inside the structure if there is interior drywall access or through different exterior locations. The problem expands rather than being contained. Void injection through an interior or exterior access point that reaches the nest chamber is the approach that eliminates the population. Sealing the entry point afterward prevents recolonization.
The fall window after natural colony die-off is the right time to apply residual to recurring nesting sites. Eave surfaces where paper wasp combs have been removed year after year, attic ventilation screens with prior yellow jacket activity, and foundation areas near prior ground nest sites all benefit from post-season residual application. It prevents the queen that overwinters from re-establishing at the same location -- the most predictable source of next year's nest problem. For properties with structural vulnerabilities -- gable vents, attic ridge vents, deteriorated fascia board gaps -- we assess those sites at the same time and discuss whether exclusion repairs would further reduce re-entry risk in future seasons.
We prioritize active stinging insect calls. Same-day service available in Chelan and surrounding Chelan, WA areas.
Call +1-866-315-0243Same-day dispatch for active nests. Scheduled visits for preventive treatment.
Full property sweep is the first step. Treatment sequence follows from the complete nest map.
Paper wasp nests removed with protective equipment, nesting sites treated with residual, seasonal prevention addressed in one visit.
Yellow jacket ground nests require direct treatment to the interior -- not surface spray at the entrance. We address the colony where it lives, not at the doorstep.
Professional treatment from safe application distance with full protective gear. The gray enclosed nest is a high-aggression situation -- correct approach and distance are required.
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.
The four steps that produce complete elimination -- not partial knockdown.
Species and location described on the call. Threat level assessed. Arrival time confirmed.
No technician is dispatched without full protective gear for the threat level involved. The equipment arrives with the technician.
The sweep happens before any treatment. Every nest type on the property is identified, mapped, and included in the treatment sequence.
Treatment sequence is determined by nest type and location -- the correct order minimizes defensive response cross-contamination. Residual applied to prevent re-establishment.
Three different nest types, three different protocols, three problems solved.
Ground nest 4 feet from the play area, Sunday morning. Show Me Pest Control answered, confirmed arrival by early afternoon. Property sweep found two more nests on the garage I had walked past multiple times. All three handled in one visit. The sweep was the part I did not expect -- most companies just treat what you call about.
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.
