Types of Wasps found in Canada

In Ontario as well as across Canada and in the United States wasps are seen in many types and sizes. The type of wasps that are of the greatest concern are yellow jackets and hornets. These are the ones which are the most nasty and can pose a great nuisance to home and business owners. Yellow jackets Yellow jackets can be a vicious wasp to encounter. Their nests are often located underground in old rodent burrows, beneath logs or in rock walls or in building walls. To eliminate wasps their nests need to be destroyed entirely and caution should be taken. It’s important to do the removal of the nest very carefully because all wasps will defend their nests. It’s best to call in professional help when dealing with yellow jackets and hornets especially because they are the most aggressive. If the nest can be located, one method to eliminate it is by applying a wasp spray insecticide into the nest opening.

Yellowjackets and hornets:

Can be distinguished from bees by their thin waists. They also fold their wings lengthwise when at rest. The yellow jacket colony will remain active for only one summer, after which the queens will fly away to start more colonies elsewhere. The remaining wasps die at the end of the summer and the nest is never reused.

Paper Wasps or Umbrella Wasp

Paper wasps, hornets and yellow jackets all construct their nests of a paper-like material which is a mixture of finely chewed wood fragments and salivary secretions of the wasps. Paper wasps typically build their umbrella-shaped nests under eaves and ledges.


Hornets are similar to yellow jackets in that they are far more difficult and dangerous to control than paper wasps. The nests resemble a large, inverted tear-drop shaped ball which typically is attached to a tree, bush or side of a building. Hornet nests may contain thousands of wasps (they are a wasp) which are extremely aggressive when disturbed. The nests are often located out of reach and removal is best accomplished by a professional pest control firm.
