Are there types of flies the Fly Parasites are not effective against?
The Fly Parasites will attack all species of the general family known as filth flies. The filth fly family includes House flies, Stable flies, Blow flies, Face flies and Horn flies among others. The main species not controlled are the extremely large Horse fly, the Deer fly and the Black fly due to their breeding on water where the parasites do not seek them. The effectiveness of the parasites is influenced by many factors including the possible influx of flies from neighboring properties. Introducing your neighbors to Fly Parasites used in a program of Integrated Fly Control can be to your benefit as well as theirs.
