Wasp & Hornet Identification – Quebec
Overview
Wasps are common stinging insects in Quebec. While some species are solitary and harmless, others, like yellowjackets and hornets, can be aggressive and dangerous when nests are disturbed. This guide will help you identify wasp species, understand their nesting behavior, and learn prevention and removal strategies.
Common Wasps in Quebec
| Species | Size & Color | Nest Type | Behavior |
|---|---|---|---|
| Yellowjacket | 1.2–1.5 cm; bright yellow and black | Ground burrows, attics, wall voids | Highly aggressive, stings repeatedly |
| Paper Wasp | 1.6–2.5 cm; brown with yellow markings | Umbrella-shaped nests under eaves | Less aggressive, but will sting near nest |
| Bald-Faced Hornet | Up to 2.5 cm; black with white face | Large gray paper nests in trees or buildings | Very territorial and aggressive |
Signs of a Wasp Infestation
- Frequent wasp activity around eaves, attics, or fences
- Visible paper nests under overhangs or in trees
- Buzzing sounds in wall voids or ceilings
- Wasps entering and exiting the same hole or crack
Prevention Tips
- Seal cracks and entry points around windows, vents, and soffits
- Keep food and garbage sealed and indoors
- Inspect eaves and sheds regularly during spring and summer
- Avoid sugary drinks and meats outside, which attract wasps
- Use decoy wasp nests in early season to discourage nesting
Why You Should Call a Professional
Attempting to remove a wasp or hornet nest yourself can be dangerous. Many species defend their nests aggressively and can sting multiple times. Professional pest control technicians have the tools, training, and protective equipment to remove nests safely and prevent re-infestation.
