Weeds, insects, animals and diseases can ravage our gardens, parks, green spaces and natural areas. It's critical to be aware of these natural predators, so The City has compiled information on the most common pests in Calgary.

Common pests in Calgary


Weeds

While weeds can be frustrating for many people, only invasive or noxious weeds need to be removed under the Alberta Weed Control Act. Common weeds and invasive plants in Calgary include giant hogweed, creeping bellflower, dame’s rocket, black henbane and toadflax.

 

While dandelions can be frustrating, they play a crucial part in the ecosystem. 
 

Noxious and Prohibited Noxious weeds belong in your black cart.

 

Insects

Each year, The City takes the necessary steps to reduce the impact of invasive insects throughout Calgary. Wasps and mosquitos are frequent visitors around the city and can cause a nuisance with bites; however, they are also vital to the overall success of our ecosystem.  

 

We are currently monitoring for the emerald ash borer (EAB), an invasive beetle that infests ash trees. While EAB has not yet been found in Calgary, we are monitoring it proactively, as early detection is critical in helping us slow the spread of EAB and prolong the life of our ash trees. Learn what you can do to help prevent the spread of this pest.

Wildlife

From squirrels to pigeons to beavers to geese, Calgary's wild animal population can burden our natural areas and city streets, but they also play a vital part in our ecosystem.
