Solitude IGR is a feed-through fly preventative, when mixed 1/2 oz into a horse's ration daily according to the directions, will prevent house and stable fly development. Repeated studies shoe up to 100% efficacy in inhibiting larvae development. Significant results may be observed within 2 weeks but the full benefit should be realized within 4-6 weeks of administration as the adult population dies off.

Cyromazine, the active ingredient in Solitude IGR, is an insect growth regulator that works on the fly's chitin exoskeleton and is very species specific to house and stable flies. Cyromazine has a well documented safety and efficacy profile. It has been extensively evaluated in horses since 2001 as well as intensely studied in othe species for more than 20 years.

Available in 2-lb (64 doses), 6-lb (192 doses) and 20-lb (640 doses) pails.
