Toronto's warm months at a glance

What this means for wasps: colonies grow through the warm months on this chart, so a nest is smaller and easier to treat early in the season.

- Locate the nest and confirm the species and entry point.
- Treat at dusk. We treat the full nest with an approved product while the colony is inside.
- Remove the nest when it is safe. We do not seal the entry hole, because trapped wasps can chew into the house.
For safety we cannot service nests above the second floor.
Products are Health Canada approved and applied according to the product label, and our technicians are licensed by the Ontario Ministry of the Environment, Conservation and Parks (MECP). Wasp and hornet nest work carries a 30-day warranty on the treated spot. A new nest in a different place is a new job.

How to Tell Wasps, Hornets, and Bees Apart Before You Call in Toronto
Bee Removal vs. Wasp Nest Removal in Ontario: Why They're Not the Same Service sets out how to check this properly. For a home in Toronto, start here.
- Common wasp nests: Smaller, open-comb structures, or built directly into soffits, eaves, and wall voids.
- Hornet nests: Large, fully enclosed, football-shaped paper structures usually hanging in trees or shrubs.
- Mud dauber nests: Solitary insects that don't defend a shared nest and typically only sting if physically handled or trapped against the skin. Low risk, low priority.
- Bees: Rounder, fuzzier bodies, slower and less erratic flight, and nests that are waxy comb structures rather than paper.
Named parks near the centre of Toronto include Larry Sefton Park, Trinity Square and Downtown Diversity Garden on Elizabeth Street, and wasps that live in green space can reach nearby homes along fences, gardens and tree lines.
Frequently asked questions: Toronto
Who removes a wasp nest in Toronto?
For a nest on your own property, the owner arranges removal. Health Canada recommends professional help.
When do the first frosts arrive in Toronto?
The Toronto station's normals show nights at or below freezing from November, about 8 days in November alone.
What does the 30-day warranty cover?
Wasp and hornet nest work carries a 30-day warranty on the treated spot. A new nest in a different place is a new job.
Do wasps leave once their nest is broken up?
No. A damaged nest can make wasps more aggressive, and survivors rebuild nearby. We treat the full nest at dusk, while the colony is inside. Around Toronto the Toronto station's mean temperature stays at or above 10 degrees Celsius from May to October, and that is the window when wasps are active.
How do I keep wasps away from the porch or pond?
Cover food and drinks, close garbage bins and treat early nests in spring, when a nest is still small. Named parks near the centre of Toronto include Larry Sefton Park, Trinity Square and Downtown Diversity Garden on Elizabeth Street, and wasps that live in green space can reach nearby homes along fences, gardens and tree lines.
