SimpliFly for Horses by Farnam Companies, Inc.

Start administering SimpliFly with Larva Stop early in the spring before flies begin to appear and continue administering throughout the summer and into the fall until cold weather restricts fly activity. This product contains an insect growth regulator which prevents the development of house flies and stable flies in the manure of treated horses, but is not effective against existing adult flies. In some cases, supplemental fly control measures may be needed in and around paddocks and buildings to control adult house and stable flies which can breed in other decaying vegetable matter or silage on premises, or that migrate in from other areas. SimpliFly should be used as part of an integrated pest management program aimed at reducing fly populations in the horse's environment. In order to achieve optimum fly control, this product should be used in conujunction with other premise and on-animal products as well as good management and sanitation practices.  more
