What You Need to Know Before Attempting Wasp Removal
Not all stinging insects behave the same way, and the treatment approach that works safely on one species can be genuinely dangerous with another. The three most common species that homeowners encounter in NM are paper wasps, yellow jackets, and bald-faced hornets, and they are meaningfully different in behavior, nest location, and defensive response.
Paper wasps build the open, comb-style nests you most often see under eaves, window frames, deck overhangs, and fence rails. The nests are unprotected and the cells are visible. Paper wasps are less aggressive than yellow jackets and will generally not sting unless the nest is physically disturbed or a person moves directly into their flight path. A small paper wasp nest on an eave away from foot traffic is low risk. A paper wasp nest above a door that slams multiple times daily is a sting waiting to happen.
Yellow jackets are significantly more aggressive and their nesting habits create more dangerous situations. They nest in ground cavities, wall voids, attic spaces, and any enclosed cavity they can find: an old rodent burrow, a gap under a concrete pad, a space inside a hollow log. A mature yellow jacket colony in late summer can contain 1,000 to 5,000 workers, all of whom will defend the nest entrance aggressively if they sense vibration or disturbance. Lawn mowers, string trimmers, and children running nearby have all triggered yellow jacket attacks on ground nests that the homeowner did not know existed. Knocking a yellow jacket nest with a can of consumer spray and running is not a safe approach with a colony of this size.
Bald-faced hornets are identifiable by their large, gray, papery nests in trees, shrubs, and sometimes attached to the eaves of structures. These nests can grow to the size of a football or larger by late summer. Bald-faced hornets are highly aggressive within 3 to 5 feet of the nest and will sting repeatedly. They are one of the few stinging insects that will actively pursue a perceived threat beyond the immediate nest area. A can of consumer wasp spray from 10 feet simply cannot reach the interior of a large aerial hornet nest effectively.
Singer Pest Control technicians approach every stinging insect call with a full property inspection, identifying all active and secondary nests before any treatment begins. We select the treatment method based on nest type and location: direct aerosol treatment for aerial paper wasp nests, ground injection for yellow jacket ground nests, and extended-reach treatment for elevated aerial hornet nests. After treatment, we apply residual to nesting sites to prevent recolonization. Our protective gear stays on throughout the job.
