Fix leaky waterers and pipes. Provide drainage around silage pits and pens to reduce water content and minimize the creation of new breeding sites. Developing a regular practice of walking about the livestock facility to identify stable fly breeding sites for elimination should be the first step in a stable fly management program. Insecticides can be used to reduce unacceptably high populations of flies, but excessive and unnecessary applications should be avoided. Unrestricted use will hasten the development of insecticide resistance in the fly population and reduce the products' effectiveness.
Insecticides work quickly to provide short-term control of adult stable flies.
Therefore, applications may be required every 1-2 weeks as new generations of adult flies appear. The most effective method is to apply sprays directly to resting surfaces used by adult flies. These can be identified by the concentrated presence of fly spots. Surface applications on vertical surfaces, rather than area sprays, should be used when possible. This practice will target adult flies, and protect beneficial insects feeding on immature flies at the breeding sites.
