Highly Palatable Feed Additive to Prevent the Development of Stable Flies and House Flies in the Manure of Treated Horses

Farnam Equitrol II 10lb


Proven to prevent development of stable and house flies in manure with 97% effectiveness.

  • Insect growth regulator Diflubenzuron prevents development of flies in manure of treated animals, but does not control adult flies.
  • Begin feeding in early spring and continue through late fall.
  • Safety studies in pregnant or lactating mares, foals and stallions have not been conducted.
  • Feed 1 oz. for thousand pound horse daily. 

Farnam® Equitrol® II Feed-Thru Fly Control contains diflubenzuron, 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.

Farnam® Equitrol® II Feed-Thru Fly Control should be used as part of an integrated pest management program aimed at reducing fly populations in the horse’s environment. Consult your retailer for program recommendations. In order to achieve optimum fly control, Farnam® Equitrol® II Feed-Thru Fly Control should be used in conjunction with other Farnam brand premise and on-animal products as well as good management and sanitation practices.
