Wasp & Hornet Nest Removal in Ontario
Do not attempt to remove a wasp nest yourself. Our licensed technicians neutralize the entire colony using full protective equipment and targeted insecticide — safely and same-day.
What Types of Wasps Do We Treat in Ontario?
Ontario is home to several species of stinging insects. All of them are dangerous when nesting near people, and all require different treatment approaches.
Yellow Jackets
Ontario's most aggressive wasp. Nest in the ground, wall cavities, and eaves. Can sting repeatedly and signal the colony to swarm.
Bald-Faced Hornets
Large, black and white hornets that build distinctive grey paper nests in trees, shrubs, and under eaves. Extremely defensive — do not disturb.
Paper Wasps
Build open, umbrella-shaped combs under eaves and in sheltered areas. Less aggressive than yellow jackets but will sting if threatened.
European Hornets
Ontario's largest wasp (up to 35mm). Active day and night, nest in hollow trees and wall voids. Rarely aggressive unless defending the nest.
Why DIY Wasp Removal Is Dangerous
A disturbed wasp nest triggers an immediate swarm response. A single yellow jacket releases an alarm pheromone that activates the entire colony to attack simultaneously.

- errorSpraying store-bought products rarely reaches the queen — the colony rebuilds
- errorNight removal is safer but still requires full protective equipment

How Does Wasp Nest Removal Work?
Assess
Our technician identifies the species, locates the nest entry point, and determines the safest treatment approach.
Neutralize
Targeted insecticide is applied directly into the nest or entry point. All workers and the queen are eliminated before the nest is touched.
Remove
Once the colony is confirmed inactive, the nest is physically removed where accessible. Residents can resume normal outdoor activity within 30–60 minutes.
Prevent
We advise on sealing cavities and applying residual deterrent to prevent re-nesting in the same location next season.
Wasp Removal FAQs
Is wasp nest removal safe for my family?expand_more
Yes, when performed by a licensed technician. Our team uses full protective suits and targeted insecticide to eliminate the colony before touching the nest. Residents stay indoors during the 15–30 minute treatment and can resume normal activity within 30–60 minutes after completion.
Can I spray a wasp nest myself?expand_more
We strongly advise against it. Disturbing a wasp nest without proper equipment triggers an immediate swarm. Yellow jackets can sting repeatedly and release alarm pheromones that activate hundreds of workers simultaneously. Multiple stings can trigger anaphylactic shock even in people with no known allergy.
Will wasps come back after the nest is removed?expand_more
Once the colony is eliminated and the nest removed, wasps will not rebuild that season. The following spring, scouts may inspect old nest sites. We advise sealing any accessible cavities and applying a residual deterrent spray to discourage re-nesting.
Do you treat bees as well as wasps?expand_more
We treat nuisance honey bee swarms and bumble bee nests in structural locations where they present a sting risk. We always advise relocation over extermination for honey bees where possible. Please call us to discuss the situation and we will recommend the most appropriate approach.
