Rated 4 out of 5 by from SIMPLIFLY REALLY WORKS prior to using Simplifly, I had so much trouble with bots and their getting on the horse's legs. After using this product for several months the bots began to diminish. I definitely think that it works.

Rated 4 out of 5 by from works well Been using this for a little over a year. definite reduction in flies. Have a fly system in my barn. Went last summer without using it. Still had a few , so this year I will run it a few time a day. Farnam says this works but best control with combining fly control. Plan to stay on it and keep reducing fly population.

Rated 5 out of 5 by from Bye Bye Flies My daughter & vet recommended using this product, so I tried it. Within a couple of weeks, I noticed a substantial decrease in the number of flies around my horse barn. I use this feed thru fly control from Spring-Fall. This product alone obviously will not eliminate all flies but is definitely part of my manure management & fly control plan.

Whether a horse is in a barn, run-in or pasture should not alter the product's effectiveness, right?
