Fly Control


During a recent survey, horse owners across the country reported that monthly costs for all of their fly season fly control efforts were topping about $16 - $24 for each horse in their care1. By contrast, Solitude IGR™ offers a scientifically advanced method to control flies for about $12 - $142 monthly for each horse.

The active ingredient in Solitude IGR (2.12% cyromazine) has been shown in multiple studies to be up to 100% effective against house and stable flies. To achieve these results, owners need only top dress their horses’ feed with one-half ounce of Solitude IGR daily. While significant results may be observed within two weeks, the full effect is usually realized in 4 - 6 weeks as the adult flies die off.

“The results of this survey tell us something we’ve long suspected – that Solitude IGR saves horse owners money, as well as reducing fly populations significantly and safely,” said Kristin Ruff, Marketing Manager, US Equine Business, Pfizer Animal Health. “More than 60% of horse owners actually reported that just fly spray use cost them up to $40 each month during their fly season. Solitude IGR compares favorably with these costs as well.”

“IGR” stands for insect growth regulator – which is the very basic explanation for how Solitude IGR works. Cyromazine, the product’s principal active ingredient, interferes with the production of chitin in house and stable flies. Chitin is a compound that makes up the exoskeleton – the hard outer shell – of many insects.

When a horse is fed Solitude IGR, the product quickly passes through the animal, exiting in the manure. Female flies lay their eggs in that manure on pastures and in stables, thus bringing their eggs into contact with Solitude IGR. The eggs hatch into larvae, but they are unable to become adults because cyromazine interferes with the formation of chitin as they molt. Larvae in the manure then die before ever emerging as adult flies.

This unique mode of action makes Solitude IGR safe. Cyromazine has been used for over 20 years in the poultry industry. Mammals, such as humans and horses, do not produce chitin, so cyromazine has no effect on them. Solitude IGR is an integral part of a sound, overall pest management program. Owners must also practice good basic barn hygiene – regularly mucking stalls and properly removing manure. Some use of fly repellents or bait systems may still be necessary to control flies that migrate from other, untreated areas.
