Great product but expensive!
I've been using the product for several years. It works. It does exactly what it says it will do. I just wish it was cheaper.Cyromazine, the active ingredient in SOLITUDE IGR, is an insect growth regulatorCyromazine is fed to the horse, passes through and is excreted in the manureHouse and stable flies lay their eggs in the manure and the eggs subsequently hatch into the larval or maggot stageAs the maturing maggots feed on the cyromazine treated manure, they become unable to successfully develop into adult flies because cyromazine inhibits the proper formation of chitin.The immature stage of the fly diesI dump my horse manure in large trash cans. I tried to go without this product for a few months a while back and my trash cans were filled with creepy crawly maggots. I continued to see these maggots until I restarted the Solitude. I've never doubted it's efficacy since!Probably would be useless in a boarding situation where only your own horses are on it.
