Treating one nest and calling it done is how a wasp problem comes back in three weeks. Our technicians in Orfordville 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.
We inspect the full property before treating any individual nest: all eave lines, soffit vents, gable ends, visible tree branches, ground areas within 20 feet of the structure, wood pile edges, and landscape features. Secondary nests are standard, not exceptional -- most properties with an active wasp problem have 2 to 4 nesting sites.
Yellow jacket ground nests can contain 5,000 or more workers and attack in numbers that overwhelm unprepared DIY attempts. Bald-faced hornet nests near a structure require approach from an angle and distance the standard spray can cannot reach. Our technicians carry full bee suits, gloves, and extension equipment for every nest type.
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 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.
The gray football-shaped nest in a tree branch or attached to a structure is the most visually distinctive of all stinging insect nests. Bald-faced hornets build it, and they are among the most aggressive stinging insects in Orfordville, WI. Nest disturbance at close range produces an immediate defensive response -- multiple workers exiting the nest and pursuing the threat simultaneously. The nest cannot be safely approached without full protective gear and appropriate application distance. Homeowners who recognize a bald-faced hornet nest but cannot reach it with a spray can often attempt to break it down with a long stick or knock it loose with a thrown object -- these approaches consistently result in stings because they agitate the colony without eliminating it.

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.
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.

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.
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.
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.
Phone assessment establishes the nest type and urgency. We confirm dispatch before you hang up.
No technician is dispatched without full protective gear for the threat level involved. The equipment arrives with the technician.
We find all of them. The nest you called about and the ones you did not know about are both on the treatment list.
All nests treated, all sites residual-treated. Documentation left on-site. Follow-up timing confirmed.
Three different nest types, three different protocols, three problems solved.
Found a ground nest 4 feet from my kids' sandbox on a Sunday morning. Called Show Me Pest Control at 9am, technician arrived by 1pm. During the property sweep, two paper wasp nests on the garage eaves were found that I had not noticed. All three nests treated the same visit. My kids were back at the sandbox Monday morning.
I sprayed a gray paper nest in a tree with a knockdown can from 8 feet away and got stung 11 times retreating. I had no idea it was a hornet nest -- I thought it was a normal wasp nest. Show Me Pest Control came out, identified it as bald-faced hornets, and treated it with extension equipment from a safe distance. Nest was inactive within 15 minutes. I would not have survived another attempt with the spray can.
Previous contractor: spray the soffit exterior, invoice, repeat. Show Me Pest Control: attic access, void confirmed, direct injection, entry sealed. Problem gone. No stings at the entrance the following year. The two approaches are not in the same category.
