Flying stinging insects that build colonies and can deliver multiple painful stings, with some species being highly aggressive
Large shiny black bodies, with yellow/white (male) or black (female) face markings, typically docile wood excavators
Slender, rusty brown with black markings and dark brown/back wings, moderately aggressive
Similar in appearance to Yellowjackets with a larger abdomen and dangling legs in flight
Bright yellow and black, aggressive, build paper nests in ground or walls
Large, black and white, aerial nests, highly aggressive when disturbed
Large, red and brown, with yellow and black banded abdomen, nests found in hollow trees, attics or wall voids
Under eaves, in trees, ground burrows, shed corners, playground equipment, outdoor dining areas
Wall voids, attics, chimneys, ventilation systems, between roof tiles, garage areas
Visible nests, increased flying activity, buzzing sounds in walls, dead insects near entry points
Tree branches, under decks, in mailboxes, irrigation boxes, dense vegetation, roof overhangs
Cover food and drinks outdoors, clean up spills immediately, secure garbage cans, remove fallen fruit
Fill ground holes, seal wall cavities, trim overgrown vegetation, remove old nests in late fall
Fix leaky faucets, empty standing water, maintain pool areas, ensure proper drainage
Wear closed-toe shoes outdoors, avoid bright colors and floral patterns, move slowly around stinging insects
Can cause anaphylaxis requiring immediate emergency medical attention
Some species become highly defensive of nests and territory
Large colonies can damage structures when building nests in walls
Aggressive colonies can make outdoor spaces unusable during peak season
Peak activity occurs during warm months when colonies are established and growing:

DIY Effectiveness: ⭐ (Very Low) – Extremely dangerous to attempt removal without proper equipment and expertise
Why Professional Treatment is Essential: Stinging insect removal requires specialized protective equipment, knowledge of species behavior, proper timing of treatments, and safe removal techniques. Disturbing nests without proper precautions can result in aggressive swarming and multiple stings.
Expected Timeline: Same-day removal for most nests, with follow-up treatments if needed for ground-nesting species
Myth: All bees and wasps are equally aggressive
Truth: Honey bees are generally docile while yellowjackets are highly aggressive
Myth: Killing one wasp attracts more
Truth: While alarm pheromones can alert others, individual wasps don’t typically call for backup
Myth: Wasps serve no beneficial purpose
Truth: Wasps are important predators that control many garden pests and agricultural insects
