Hornet Removal in NYC — Nest Elimination, Same Day When Needed
Hornets in New York City — primarily bald-faced hornets and European hornets — build large paper nests that become a serious hazard by late summer. A bald-faced hornet colony can reach 400–700 workers by August and will aggressively defend a 3-foot perimeter around the nest with little provocation. Bald-faced hornets sting multiple times without dying (unlike honeybees), respond to nest vibration from lawn equipment or foot traffic, and release an alarm pheromone when they sting that signals the colony to attack. A nest near a high-traffic area is a medical emergency risk — multiple stings can cause anaphylaxis even in people with no prior allergic reaction.

About Hornet Removal in NYC
The nest location determines the treatment approach. Exposed aerial nests on tree branches, under eaves, or attached to siding are accessible for direct aerosol treatment at night when workers are inactive. Nests inside wall voids, attic spaces, or in dense vegetation require a different approach — and attempting to seal a wall void without killing the colony drives workers into the living space. European hornets, which are larger and brown/yellow rather than black/white, are nocturnal and often build inside hollow trees, attic spaces, and wall voids — their presence may not be obvious until the colony is well established.
Hornet nests are annual — the queen overwinters and builds a new nest each spring. The same location will be reused only if the previous nest structure is still there. Removing the nest after treatment prevents reuse and eliminates the risk of a secondary pest infestation from insects feeding on dead hornets.
Signs of Infestation
- ⚠Large (football to basketball size) gray paper nest under eaves, in tree branches, on siding, or on outdoor structures
- ⚠Frequent hornet activity near a specific point in a wall, soffit, or roof line — indicates a wall void nest
- ⚠Hornets entering and exiting through a single crack or gap in the structure
- ⚠Nocturnal buzzing in a wall or ceiling — European hornets
- ⚠Aggressive hornet behavior when near a specific area of the yard or structure
- ⚠Paper nest material visible inside an attic or garage

Our Treatment Approach
Hornet treatment is performed at night when colonies are fully in the nest and cold temperatures reduce activity. Accessible aerial nests receive direct aerosol treatment with fast-knockdown pyrethrin followed by residual dust application into the nest opening. Wall void nests receive dust injection into the void space through identified entry points — the dust provides immediate kill and residual action that continues for several days as workers contact the treated void. Nest removal is performed 48–72 hours after confirmed activity cessation. We provide a 30-day guarantee: if the colony is not eliminated, we return at no charge.
Bald-Faced Hornets vs. European Hornets in NYC — What You're Dealing With
Bald-faced hornets build the large, gray papery nests often seen in trees and on building exteriors from summer through fall — they're extremely aggressive within 3 feet of the nest and sting without provocation. European hornets are larger (up to 1.5 inches), active at night, and typically nest inside hollow trees, wall voids, and attics in older NYC homes. Both species are at peak population and most aggressive in August and September.
Why Hornet Nests Grow Faster Than You Think
A hornet colony starts with a single overwintering queen in spring and can reach 400–700 workers by late summer — the colony doubles in size during July and August. A nest the size of a baseball in June will be the size of a basketball by September. Early-season removal (May–June) is dramatically easier, safer, and less expensive than late-summer removal when colonies are at maximum size and aggression.
Is It Safe to Remove a Hornet Nest Yourself?
No protective equipment available to the general public provides adequate protection against a disturbed hornet colony at peak size. Bald-faced hornets can sting multiple times without losing their stinger and recruit dozens of defenders within seconds. Professional removal is conducted after dark with full protective suits, direct nest-cavity treatments, and proper disposal — the risk of anaphylaxis for individuals with unknown allergies makes even a single sting a medical emergency.
Frequently Asked Questions
Can I knock down the nest myself?▾
Not recommended — and not at night either, since hornets are attracted to flashlight beams. Bald-faced hornets respond to nest disturbance with mass attack. We use purpose-built protective suits, pressurized aerosols with a 15-foot stream, and confirmed nighttime colony rest periods. Improper nest removal sends hundreds of hornets into attack mode.
Will the hornets come back next year?▾
Not to the same nest — the colony dies in winter and the queen hibernates elsewhere. But new queens may build in the same location if it's an attractive nesting site (sheltered, elevated, near food). Nest removal after treatment and sealing of wall void entry points prevents reuse.
Are hornets more dangerous than wasps?▾
Bald-faced hornets are significantly more aggressive than yellowjackets or paper wasps, particularly when the nest is large (late summer). Any nest near a high-traffic area should be treated promptly. European hornets are less aggressive but sting when handled or when the nest is disturbed.
How much does hornet removal cost in NYC?▾
Hornet removal starts at $350–$550 depending on nest size, location, and accessibility. Nests inside wall voids may require additional access work. Written estimate provided before starting.
What makes hornets more dangerous than other stinging insects?▾
Hornets — particularly bald-faced hornets — are uniquely aggressive defenders of their nest. Unlike honeybees, they can sting multiple times without dying. They also release an alarm pheromone when threatened that signals other colony members to attack, meaning disturbing a hornet nest can trigger a coordinated assault from dozens of insects simultaneously. For people with venom allergies, this is a genuine medical emergency risk.
Can I wait until winter to deal with a hornet nest?▾
Technically the colony will die off in late fall, but the nest itself can attract new queens the following spring who will use it as a starting point — or the structure will decay and create entry points for other pests. Additionally, waiting through summer and fall means months of infestation risk. We recommend removal as soon as a nest is identified.
