Good sanitation is the basis for all fly control programs.
Sanitation is at least 75 percent of the fly control program preventing fly breeding. Nevertheless, it is often necessary to supplement sanitation practices with pesticides. For successful fly control, organize a control program that best fits your farm. A single pesticidal product rarely gives the most effective and economical control. It is normally best to use a combination of pesticide applications such as residual wall sprays, space or aerosol sprays, baits, etc. during the fly season.
