SimpliFly™ with LarvaStop™ is a highly palatable feed additive to prevent the development of stable flies and house flies in the manure of treated horses. LarvaStop™ breaks the fly life cycle by preventing the formation of fly larvae when they molt (resulting in their death). Contains no organophosphates.
Directions:

Start feeding early in the spring before flies begin to appear and continue feeding throughout the summer and into the fall until cold weather restricts fly activity. No testing has been done on pregnant mares or breeding stallions. Contact your Vet for advice on use if feeding to pregnant mare or breeding stallions.
