Hornet Nest Removal in Toronto & GTA
Bald-faced hornets build large grey nests on GTA homes and trees, with colonies reaching 700 members by late summer. Hornet nest removal requires insecticide dust injected directly into the nest — one missed entrance leaves the colony intact.

Final cost depends on severity, property size, and treatment method.
Bald-faced hornets are the large black and white wasps that build the grey, papery football-shaped nests you see hanging from tree branches and building eaves in the GTA. They are not technically hornets — they are in the yellowjacket family — but they are more aggressive and deliver a more painful sting than most wasps. A mature bald-faced hornet colony can reach 700 members by late August.
The other hornet species found in the GTA is the European hornet, which is larger than our native species and nests in wall voids, hollow trees, and attic spaces. European hornet activity in GTA homes increases in late summer when the colony is at peak size and foraging pressure is highest.
Hornet nest removal requires insecticide dust injected directly into the nest entrance. The dust clings to hornets as they exit and enter, spreading through the colony including the queen. This eliminates the entire colony within 24–48 hours. Aerosol sprays cannot reach deep into the nest structure.
How It Works
What to expect when you work with licensed hornet removal professionals.
Inspection
The technician locates the nest, identifies the species, and evaluates the size. Bald-faced hornets build grey paper nests in trees and on building exteriors. European hornets nest in wall voids and hollow trees. Nest size and species determine the treatment method.
Treatment
Professional insecticide dust is injected directly into the nest entrance. The dust clings to hornets as they exit and enter, spreading through the colony including the queen. This eliminates the entire colony within 24–48 hours. Nests are then removed to prevent reuse by other wasps the following season.
Prevention
For wall-void nests, the entry hole is sealed after treatment to prevent future colonies from using the site. The technician inspects the surrounding area for other potential nesting sites and treats them preventively with residual insecticide.
Signs You May Need Hornet Removal
-
Large grey, papery nests attached to tree branches, under eaves, or on building exteriors — can reach the size of a basketball
-
Large black and white hornets flying aggressively near a specific area of the property
-
Aerial wasps or hornets entering and exiting a gap in the siding, soffit, or roofline
-
Increasing hornet activity around outdoor eating areas and garbage bins in mid to late summer
-
Hornet bodies accumulating below a specific spot — indicates a nest above
-
Distinctive loud buzzing from inside a wall or hollow tree — a hidden wall-void nest
Why Hire a Professional
-
Hornets defend their nest aggressively and can sting repeatedly. For anyone with a bee sting allergy, a hornet encounter near a nest is a medical emergency.
-
Wall-void hornet nests are invisible from outside. DIY sprays applied to the entry hole are rarely effective and drive the colony deeper into the wall structure.
-
Insecticide dust is the only effective treatment for hornet nests. Aerosol sprays cannot reach deep into the nest structure. Professionals use injection equipment designed for this application.
-
Bald-faced hornet colonies can reach 700 members by late August. A nest that seems small in June can be a serious hazard by late summer.
-
Proper hornet removal includes nest removal, which prevents secondary infestations from other wasps using the same structure the following season.
