Knowledge of Sanitation

The primary cultural means to control flies is to reduce their ability to breed. Breeding sites should be identified by regular monitoring and actions must be taken to eliminate or mitigate fly breeding sites. Here are a few general suggestions:

Stop water leaks promptly. This seems like common sense, but it's a big problem. Watering systems get nasty and clogged up, hoses crack, pipes crack, joints leak, and if you don't catch them early, you have a fly problem that won't quit. Check the water supply everyday.

Manage feed storage areas. Keep feed cleaned up around silos and feed bins. This can be an ideal breeding site with enough moisture.

Maintain adequate ventilation. Air flow through areas where manure collects is critical to maintaining dry manure. Dry manure means less fly breeding.
