Solitude IGR Feed Through Fly Preventive 20 lb

I have used fly predators and Solitude for years. I have found starting Solitude in early March (hardiness zone 6b) has made all the difference. I can't start putting fly predators out until mid-April at the earliest. My horses live next to a cow farm that practices little fly control, if any. My farrier tells me I have the least number of flies of all the farms he visits.

Been using this product for the past 4 years and it does work. I have 4 equines on my property, all of them are on this, you do have to start early, and keep using all summer. I'm in S Texas and I start around Feb and use until at least Oct. My vet referred this product.
