Premise Fly Sprays
Premise sprays offer quick knock-down of adult flies and are a great choice for barns with lots of bug activity. These larger barns may want to invest in a premise spray system, which is a series of tubes with misting heads that release insecticides at regular intervals. Some fly sprays can also work as premise sprays and can be sprayed around the barn to create a "no-fly-zone". Simply spray them around doors and windows, or in areas you notice flies tend to hang around, to discourage flies from entering.
