DIY spray aimed at a wasp nest from 10 feet away increases aggression and rarely eliminates the full population. Show Me Pest Control's technicians in Strathmore arrive with proper protective equipment, locate every nest on the property, and eliminate them in the correct sequence.

Full sweep, correct sequence, residual prevention -- the complete wasp elimination protocol.
Before treating the nest you called about, we sweep the property for all others. Eaves, soffits, attic gable vents, tree branches, ground depressions near the foundation, hollow landscape features -- all checked before treatment begins. Finding the nests you did not know about is the most important part of the job.
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.
Treated nesting sites without a residual barrier become next year's nesting sites. We apply residual product to all treated locations -- eave surfaces, ground openings, former void entries -- so that returning queens cannot re-establish. The prevention step is what makes wasp removal last more than one season.
Paper wasps build open-comb nests visible to the naked eye -- small clusters of hexagonal cells attached to a surface by a single stalk. They are identifiable by their thin waist and long dangling legs in flight. They are not defensive at a distance and do not pursue -- the risk from paper wasp nests comes from proximity and direct physical contact with the nest or the immediate surrounding structure. Removal is straightforward with proper protective equipment. The priority is applying residual to the site after removal to prevent the following season's queen from re-establishing at the same location.
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.
Bald-faced hornets are a yellow jacket relative -- technically a wasp -- that builds the large, gray, papery football-shaped or teardrop-shaped nests visible in trees, attached to structures, and sometimes on utility poles or equipment. Despite their distinctive appearance, many people do not recognize bald-faced hornet nests and attempt to knock them down with a spray can from a short distance. This is consistently dangerous. Bald-faced hornets are highly aggressive within several feet of the nest and will pursue a perceived threat away from the nest site -- they do not limit their defensive response to the immediate nest perimeter the way paper wasps do. A large bald-faced hornet nest can contain 400 to 700 workers by late summer. Treatment requires approaching from a downwind angle at maximum application distance with appropriate protective equipment -- it is not a situation where proximity with a standard spray can is safe for an unprotected person.

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 Strathmore and surrounding Strathmore, CA areas.

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.
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.
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 nest identification by entry pattern and acoustic confirmation. Treatment through interior or exterior access point to the nest chamber -- not at the entry hole. Entry sealed after colony elimination to prevent recolonization and structural moisture issues.
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.
Species and location described on the call. Threat level assessed. Arrival time confirmed.
Every technician arrives equipped for all nest types. The equipment appropriate to the specific situation is already on the vehicle.
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.
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.
