Farnam SimpliFly reduces fly population by 97-100%!

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 formulation of fly larvae's exoskeletons when they molt (resulting in their death). Does not contain organophosphates and can be used as part of an integrated pest management programme.

SimpliFly works as the SimpliFly treated manure cannot support the flies life cycle as the mother fly must search for fresh manure as a food source for her eggs & larvae. Thus, the whole manure on the property cannot support flies and the flies go elsewhere to support their eggs.

  • Start feeding Farnam SimpliFly before flies begin to appear and continue feeding throughout the summer and into the autumn until cold weather restricts fly activity.

  • This product contains an insect growth regulator which prevents the development of house flies in the manure of treated horses, but is not effective against existing adult flies. Active ingredient; Diflubenzuron 0.24%.

  • 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 the premises, or that migrate in from other areas.

Farnam SimpliFly should be used as part on an integrated pest management program aimed at reducing fly populations in the horse's environment. Feed the recommended dosage to each horse separately to make certain he receives his full portion. This product should be fed top dressed on grain or mixed with the horse's total ration to provide 6.8mg of diflubenzuron per 100 lbs bodyweight.
