After maximum effort to suppress fly numbers by proper cultural and biological methods, insecticides are often needed to achieve the desired degree of fly control.
If fly suppression by cultural and biological methods is maximized, then the effectiveness of insecticide treatments will be enhanced, and the rate of development of fly resistance to the insecticide will be reduced.
The most effective insecticide use is as part of an integrated control program, in conjunction with cultural and biological methods.
Insecticides are either adulticides (baits, spray-on, paint-on), or larvicides (spraying breeding sites and using feed additives).
