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 Murrysville, PA 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.
Yellow jackets are a fundamentally different threat category than paper wasps. They are highly social, produce large colonies -- 3,000 to 5,000 workers or more by late summer -- and become extremely defensive within 20 feet of the nest entrance. Yellow jackets do not give a visual warning before stinging, do not sting once and release like bees, and can sting repeatedly. A disturbed yellow jacket ground nest produces a mass defensive response that can overwhelm a person retreating from the nest site, particularly if the person does not know the nest entrance location in advance. Ground nests are particularly dangerous because the entrance is frequently not visible until approached -- it may be a small hole at the base of a landscape feature, in a lawn edge, or between pavement slabs. Yellow jackets in Murrysville, PA do not reliably die off in mild winters -- colonies that experience only moderate cold may survive into the following season with a surviving queen and many workers, allowing the colony to reach much larger populations than typical first-year colonies.
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.
We prioritize active stinging insect calls. Same-day service available in Murrysville and surrounding Murrysville, PA areas.
Call +1-866-315-0243From initial property sweep to preventive fall application -- the complete stinging insect protocol in Murrysville.
Full property sweep is the first step. Treatment sequence follows from the complete nest map.
Treatment includes removal and the residual application that prevents next-season re-establishment at the same site.
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.
Hornet nests in trees and on structures treated from a safe distance with professional equipment. Do not attempt DIY treatment on enclosed hornet nests.
Void injection, entry sealing, and structural assessment -- the complete protocol for wall and attic yellow jacket colonies.
Applied after the current season's colony dies off or is eliminated. Prevents next year's nest at the same location.
Threat assessed, all nests located, treated in correct sequence, residual applied.
Species and location described on the call. Threat level assessed. Arrival time confirmed.
Full bee suits, extended-reach application equipment, and species-specific products. The protective protocol is matched to the nest type described on the call -- not a one-size approach.
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.
Treatment sequence is determined by nest type and location -- the correct order minimizes defensive response cross-contamination. Residual applied to prevent re-establishment.
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.
The soffit spray was not working and the contractor could not explain why. Show Me Pest Control confirmed a void nest the moment they looked in the attic. Treated directly, sealed the entry. First season without stings at the entrance in two years.
