How to Get Rid of Wasps in Calgary (2026)
Wasp season in Calgary runs from June through September, with peak activity in August. A single wasp nest can house thousands of aggressive insects — and they will sting repeatedly if threatened.
Types of Wasps in Calgary
Yellow Jackets (Most Common)
Small, aggressive, and territorial. Yellow jackets build paper nests in wall voids, under decks, and in the ground. They are extremely defensive and will chase threats.
Bald-Faced Hornets
Larger than yellow jackets. Build large, grey paper nests in trees, eaves, and bushes. Very aggressive when disturbed.
Paper Wasps
Less aggressive but still capable of stinging. Build small, open-celled nests under eaves and overhangs.
Wasp Nest Removal: The Dangers
DIY wasp removal is dangerous. Each year, Calgary-area residents are hospitalized from wasp stings during amateur removal attempts. Disturbing a nest without proper equipment triggers a mass defensive response.
Never attempt to remove a nest if:
- The nest is larger than a golf ball
- The nest is inside a wall void or structure
- You or anyone in your household has a bee/wasp allergy
- The nest is near a frequently used area
Safe DIY Prevention
- Seal entry points in walls, eaves, and soffits before spring
- Remove food sources — keep garbage sealed, clean BBQ grills
- Hang decoy nests early in spring (wasps are territorial)
- Plant wasp-deterrent plants like spearmint, eucalyptus, or lemongrass
