Hornet Removal in Toronto

Typical Cost in Toronto

$150–$500

Final cost depends on severity, property size, and treatment method.

Toronto has more raccoons per square kilometre than any city in North America. That is not a guess — biologists have been tracking them for decades. The Don Valley ravine system runs from the waterfront up through Leaside and into North York, and it functions as a raccoon highway delivering wildlife directly into residential backyards. In the Annex, raccoons den in the attics of 120-year-old Victorians where the original soffits have never been replaced. In Parkdale, mice pour into century semis through crumbling mortar joints every October. In Liberty Village and CityPlace, bed bugs move between condo units through shared plumbing risers faster than property managers can respond. Every Toronto neighbourhood has its own pest profile, shaped by housing age, tree canopy, and how close you are to a ravine.

Our Hornet Removal Process in Toronto

1

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.

2

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.

3

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 Need Hornet Removal in Toronto

  • 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 in Toronto

  • 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.
