Wasp Nest Removal in Ontario

Professional Wasp Nest Removal Across Ontario

Wasp season in Ontario runs from approximately late April through early October, and it follows a predictable escalation that most homeowners don't fully appreciate until a nest becomes dangerous. In May and June, a new yellow jacket colony started by a single overwintering queen is small — perhaps 50 to 200 workers — and manageable with the right approach. By August, that same colony can contain 3,000 to 5,000 workers in peak condition, defending an established nest aggressively. A nest discovered in late summer is a fundamentally different situation than the same nest treated in June.

We provide safe, thorough wasp nest removal for all nest types and all locations across Ontario. Whether the nest is on an eave, hidden inside a wall void, or built underground in a lawn or garden, we treat it completely using professional-grade products and appropriate protective equipment. Most wasp nest removals are completed in a single visit. The earlier in the season we treat, the simpler and less hazardous the service.

Wasp Species Common in Ontario

Yellow Jackets

Yellow jackets are the most common stinging insects requiring professional removal in Ontario. They build large paper nests in eaves, soffits, wall voids, attic spaces, and underground — often in abandoned rodent burrows. They are highly territorial and aggressive when their nest is disturbed, attacking in large numbers. By late summer, yellow jacket nests can contain several thousand workers, making them a serious hazard.

Bald-Faced Hornets

Bald-faced hornets build distinctive large, grey paper nests that are usually visible on tree branches, shrubs, or the sides of buildings. Despite the name, bald-faced hornets are actually a type of yellow jacket. They are highly aggressive when their nest is threatened and should never be approached without protective equipment. Their nests are perennial in structure but are abandoned each fall and rebuilt from scratch each spring.

Paper Wasps

Paper wasps build smaller, open-celled nests shaped like an upside-down umbrella, commonly found under eaves, porch railings, deck structures, and window frames. They are less aggressive than yellow jackets but will sting when their nest is threatened. Paper wasp nests are smaller and generally less hazardous, but should still be professionally removed when located near high-traffic areas.

Our Wasp Nest Removal Process

Every wasp removal service follows the same professional process:

• Site Assessment: We identify the nest location, access point, species, and colony size before approaching. For wall void and underground nests, we determine the best treatment approach before beginning.
• Protective Equipment: Full protective suits and equipment are worn for all wasp nest removals, regardless of apparent nest size. Safety is not optional.
• Treatment: For exposed nests, we apply a fast-acting residual insecticide directly into the nest entrance at a time of day when colony activity is at its peak to maximize contact. For wall void nests, we use injection application directly into the void. For underground nests, we apply treatment directly into the tunnel entrance.
• Nest Removal (where accessible): After colony elimination is confirmed, we remove the physical nest structure where safely accessible. This prevents attraction of scavengers and removes the nesting substrate.
• Deterrent Treatment: We apply residual deterrent at the removal site and nearby potential nesting locations to discourage reconstruction in the same area.

When to Call for Wasp Nest Removal

Do not wait until a nest is large or poses an imminent threat. Call us when:

• You notice wasp traffic around a specific area of your home or yard
• You find a nest — regardless of current size
• You or a family member has a known stinging insect allergy
• The nest is located near a door, window, or regularly used outdoor space
• You hear buzzing inside a wall or in a floor void
• You notice an underground nest in a lawn, pathway, or garden bed

Early-season nests in May or June are significantly easier and less risky to remove than nests at full late-summer population. A nest found in June typically requires one treatment and presents minimal hazard. The same nest left until September may contain thousands of workers in a highly defensive posture. Acting at the first sign of activity is always the right call.

One situation that catches people off guard every year: underground yellow jacket nests in lawns. These are often invisible until someone steps near the entrance and triggers a defensive response. If you've seen yellow jackets repeatedly flying low along the same path across a lawn or garden area, that behaviour almost always indicates an underground nest entrance nearby. It is worth having it located and treated before it is disturbed accidentally.
