The majority of flies in and around Canadian farms can be controlled using a Fly Parasites program. It is however important to understand that Fly Parasites only attack flies that breed in manure, compost or other similar material. They will not control flies that breed in or have the pupa stage in water. Below is a list of the most common flies that are found around Canadian farms.
