An active nest near a doorway or walkway is a real hazard, especially for anyone with an allergy, and NYC's building stock gives stinging insects plenty of places to hide — brownstone cornices, fire escapes, eaves, and the gaps around window air-conditioner units are the usual spots after twenty years of these calls.
Yellow jackets and hornets are aggressive when a nest is disturbed, which is exactly what happens with most DIY removal attempts. Our licensed technicians locate the nest — including ones tucked into wall voids or high on a building facade — and treat it with the right protective equipment, so the colony doesn't rebuild in the same spot afterward.
Honeybees get different treatment: where possible, we point customers toward safe relocation rather than extermination, because pollinators matter and the two situations aren't the same call.
Stinging insects around a NYC home: how do you tell them apart and remove them safely?
UC IPM notes that a yellowjacket nest is enclosed by a paper envelope with a single entrance hole and is often built in protected cavities such as voids in walls and ceilings, whereas a paper wasp nest hangs like an open umbrella from a stalk with its cells visible from beneath, typically under eaves or in attics — so the nest shape tells you which insect you are dealing with. (UC IPM — Yellowjackets and Other Social Wasps)
Per UC IPM, only about one to two people per 1,000 are allergic or hypersensitive to bee or wasp stings, but for those people a sting can trigger life-threatening reactions such as shock, dizziness, difficulty breathing or throat swelling that blocks the airway — all of which require immediate medical care. For most people stings are painful rather than dangerous. (UC IPM — Bee and Wasp Stings)
CDC/NIOSH advises that while most insect stings cause only minor discomfort, some produce severe allergic reactions that require immediate medical care and can be fatal, and that anyone with a history of severe reactions should carry an epinephrine autoinjector and wear medical-ID jewellery. This is why a nest by a doorway or high-traffic area is treated as urgent. (CDC/NIOSH — Insects and Scorpions)
Not every stinging insect should be exterminated. Penn State Extension explains that honey bees play a major role in pollinating agricultural crops, and that a honey bee swarm is docile enough for a beekeeper to shake into a box and relocate to a hive — which is why a reputable service identifies honey bees and arranges relocation rather than killing them.

Yellowjacket vs paper wasp vs hornet vs honey bee
| Feature | Yellowjacket | Paper wasp | Hornet | Honey bee |
|---|---|---|---|---|
| Body | Short waist, bright black-and-yellow, near-hairless | Slender body, long dangling legs, distinct waist | Larger social wasp, black with white/pale markings | Rounder, hairy, less brightly striped |
| Nest | Paper envelope, single entrance; ground or wall/ceiling voids | Open umbrella of visible cells on a stalk, under eaves | Large enclosed grey paper envelope, often aerial | Wax comb; a colony in hives or wall voids |
| Temperament | Defends nest vigorously when disturbed | Much less defensive; rarely stings humans | Defends nest aggressively if disturbed | Unlikely to sting unless trapped or stepped on |
| Right response | Treat/remove nest; pro PPE for in-wall voids | Often leave alone unless by a doorway | Treat/remove nest with professional care | Relocate via a beekeeper — do not exterminate |
Signs you have a stinging insect removal problem
- A visible nest under eaves, in a wall void, or near a door or window
- Steady wasp or hornet traffic to one fixed spot on the building
- Aggressive stinging insects around a walkway, entrance, or fire escape
Why NYC sees this
Since 2006, we've treated stinging-insect nests across every borough's building types — brownstone cornices and fire escapes in Brooklyn and Manhattan, eaves and rooflines everywhere else.
Active nests are treated as a priority call, not scheduled behind routine work, because the hazard is immediate.
New York discourages the extermination of honeybees specifically given their role as pollinators — where a colony is confirmed as honeybees rather than yellow jackets or wasps, our licensed technicians point customers toward a beekeeper for relocation instead of treating it as a kill job.
