The term wasp includes a broad category of flying insects ranging from paper wasps and mud daubers to the highly common yellow jackets and hornets found throughout Canada. The typical diets of wasps largely include other insects and arachnids. Wasps also feed on sweet liquids like nectars. Areas containing ready access to smaller, sustainable insects and spiders often appeal to wasps. Human food waste serves as a popular draw, as well. The social creatures often converge on trash cans located at schools, public pools, or other high-traffic outdoor parks where food consumption takes place. The insects take particular interest in the sucralose, sucrose, glucose, and other forms of sweeteners found in popular, modern food items, such as high fructose corn syrup-based treats or exposed and decomposing meats. Foods left out attract other insects, which provide both forms of preferred sustenance.

Preexisting burrows or former residences of small rodents or other tiny mammals can also attract wasps. Wasps prefer to build nests either underground or in shrubs, trees, or bushes. Many species of wasps assume homes or nests already burrowed out or created by other wasp or bee colonies or smaller mammals, as mentioned before. Sandy or bare soils prove likely to host wasp colonies. Voids in walls encased with soft materials like drywall or in abandoned vehicles also sometimes suit the needs of wasps for building nests. Large holes in trees typically represent another common location for wasps in Canada to reside.
