Farnam SimpliFly Feed Through Fly Control for Horses, 3.75 lbs, 60 Day Supply, EPA-Approved Pellets to Prevent Stable Flies in Manure – Safe, Palatable Daily Supplement for Fly Population Control

This product works. We started year before last and saw a significant decrease in horse flies. It’s not perfect, but it makes things better.

Seems to work for some files, not all.

So we started Simplifly in Spring then added the Natural Fly Extermiator bags all around the horses and donkeys then wrapped poles and all of our trash cans in Giant Fly glue tray rolls by Catchmaster. Not sure which is working the best but I know all 3 together is amazing. Today was 100 and not but one fly while I was mucking out the horses. We have both horses and donkeys and we are all so amazed. The fly paper has to be changed almost every day, but once under control maybe every few days. The paper catches so many flies it's the craziest think. We are all so happy at the ranch.

Surprised at how well this works. Wish I would have purchased years sooner.

I cuts down on the fly population and is well tolerated by my horse.Cancelling subscription because product arrived and the lid had come off the tub. The product was loose in the box. I poured the pellets back into the tub and replaced the lid but it will not stay on so I will use the previous tub for a container. In the process, some of the product was lost and I am guessing the postoffice got to clean some up, too, as the tub is not as full as usual. I do not have time to send this shipment back. I will say that I have been buying this product for years and this has never happened before.

I think it works…it’s hard to tell what things would look like otherwise. The flies still love to be all over the horses but I genuinely don’t see a ton on the piles of poo, which is the point.

I used to use Solitude fly pellets but they are so expensive so I decided to try this brand and to be honest I haven’t noticed a change, it works just as well. I mix it in with my horse feed everyday and if you notice the flies on your horse poop will decrease, mine doesn’t have but maybe 1-2 on it. It works in the poop because that’s where the fly larva grows and this stops this from happening so the flys can’t produce more flys from your horse poop. It’s a must have in our barn!

My package was broken open and supplements were falling out all over the place! Way to expensive to be losing product.
