A product made by Pfizer for use in helping control flies in stables, barns, and paddocks, Solitude IGR, prevents the development of houseflies and stable flies in the treated manure from the horse, but is not effective against existing adult flies.
Control flies in stables, barns, and paddocks
Cyromazine disrupts the production of chitin in the fly so the larvae (maggots) cannot develop into adults.
The active ingredient, cyromazine, is very insect specific. Cyromazine disrupts the production of chitin in the fly so the larvae (maggots) cannot develop into adults. Once the fly reaches adulthood, cyromazine has no effect on the chitin of the adult fly.
Horse owners are advised to begin feeding Solitude IGR early in the spring before flies begin to appear and continue feeding throughout the summer and into the fall until cold weather inhibits fly development
Feed the recommended dosage to each horse separately to make certain full ration is received. This product is to be fed top-dressed on grain or mixed with the horse's total ration to provide 300 mg (1 scoop) of cyromazine per horse per day or 600 mg (2 scoops) of cyromazine per horse every other day.
Repeated studies show up to 100% efficacy in inhibiting larvae development and significant results may be observed within 2 weeks but the full benefit should be realized within 4-6 weeks of administration as the adult populations die off.
In some cases, supplemental fly control measures may be needed in and around paddocks and stables to control adult houseflies and stable flies, which can breed not only in manure, but in other decaying vegetable matter or silage on premises.
In order to achieve optimum fly control, Solitude IGR should be used in conjunction with other good management and sanitation practices.
