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 Corydon 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.
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.
Every technician dispatched for wasp removal carries full protective equipment and species-specific treatment tools. The protective protocol is not the same for a small paper wasp eave nest as it is for a large yellow jacket ground colony. We size the response to the threat.
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 nest elimination, we apply a residual treatment at the nesting site -- eave boards, ground nest entrance, void entry point -- that prevents new queens from establishing a colony at the same location next season. Wasps show strong site fidelity and will return to previous nesting locations if no residual barrier is present.
Paper wasps are the most common stinging insect encountered by homeowners in Corydon, IN. 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.

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.

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 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.
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.
