Identification

Ontario's Most Aggressive Wasp

Yellow jackets are medium-sized (12–15mm), bright yellow and black wasps that are commonly mistaken for bees. Unlike bees, they are smooth, fast, and extremely aggressive when their nest is threatened. They nest in the ground, in wall voids, attics, and beneath deck boards making them especially hazardous to encounter unexpectedly.

Signs of Infestation

Yellow jacket warning signs:

  • Wasps entering and exiting a hole in the ground or a wall gap
  • High activity near a wall void, deck, or underground location
  • Aggressive wasp behaviour when you approach certain areas
  • Visible yellow and black insects near outdoor food or garbage
  • Papery nest visible in an attic, shed, or under eaves
Health & Safety

Multiple Stings, Serious Reactions

Yellow jackets can sting repeatedly and do not lose their stinger like honeybees. For those with allergies, a yellow jacket encounter can cause anaphylaxis. Even without an allergy, multiple stings from an agitated colony can cause serious reactions. Ground nests are particularly dangerous as they can be stumbled upon accidentally.

Our Treatment

Ground & Structural Nest Treatment

Yellow jacket treatment requires direct nest treatment not just perimeter spraying. Our technicians apply professional insecticide directly into the nest entrance at the optimal time, neutralizing the colony. For in-wall nests, we may need to access the void to ensure complete elimination.
