Wasps establish their colony by building nests. Depending on the species of wasp, their nest can be built in areas with debris, wall openings, outdoor clutter or overgrown foliage. If there are food sources present in the area, wasps are more likely to establish a colony. These pests are scavengers, preying on insects and meat protein. If you are concerned about a possible wasp infestation on your property, it is important to contact your local Orkin Canada branch.
