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 Campbell arrive with proper protective equipment, locate every nest on the property, and eliminate them in the correct sequence.
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.
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 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.
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 Campbell, CA 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.
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.
Same-day response for active wasp and hornet nests in Campbell. Call and we confirm arrival before you hang up.

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.
Ground nest entrance located, treated with professional insecticide applied to the colony interior, entrance sealed after elimination. Full protective equipment required -- proper protocol produces safe, complete elimination of even large late-season colonies.
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.
The entry-point spray fails for void nests. We access the nest chamber directly, treat at the source, and seal the entry.
Preventive fall treatment is the most cost-effective protection against recurring annual nesting at known sites.
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.
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.
We find all of them. The nest you called about and the ones you did not know about are both on the treatment list.
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.
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.
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.
