Wasps control in Canada
Nests near doors, decks and play areas should be removed, not poked.
How to identify it
Slender yellow-and-black insects with smooth bodies; paper nests under eaves, decks or in wall voids.
Signs of an infestation
- Repeated wasp traffic to one spot on the building
- Visible papery nest under soffits or railings
- Aggressive wasps around garbage or patio food in late summer
Is it dangerous?
Stings are painful and can be life-threatening for anyone with a venom allergy.
Can I handle this myself?
DIY may be reasonable
A small, new nest far from the house can sometimes be handled carefully at dusk.
When to call a professional
Call a professional for nests near entrances, in wall voids or roofs, large late-summer nests, or if anyone in the home has an allergy.
Any pesticide used in Canada must be registered here and applied exactly as its label directs. We don't publish application instructions.
