Common Vegetable Pests of Alberta

There’s nothing more frustrating than investing all your time and hard work into a vegetable garden only to have it decimated by harmful insects. There are many strategies gardeners can use to help deter and manage damage from such pests, but the first step is identifying what the heck is destroying your crops. Below are the most common culprits for our Alberta vegetable gardens. Once a visual identification can be made, whether its of the pest itself or by the damage it has done, steps can be taken to manage the situation and limit your losses.

Helpful Hint : Most insects have a life cycle where their form changes and they can look and behave completely differently depending on their stage of life. Quite often it is the larvae stage that can be most harmful to our veggies.
