Get a jump start on fly prevention this year with Farnam SimpliFly Feed-Thru Horse Fly Control.

Designed to significantly reduce fly populations.
Your hoofed buddy will love the taste—just add the pellets to her feed!
Contains an insect-growth regulator that breaks the fly life cycle.
Contains diflubenzuron. Contains no organophosphates.
I found about this at a barn of 40 horses the owner required horses be on fly control. We had 7--80% reduction in flies when all horses in stalls and pastures were on this or the slightly more expensive competitor (which is about the same but you feed less as its a bit more concentrated). This is the more cost effective solution for fly management.
This product works if you use it right. It takes at least 30 days to build up and become effective. Also, it's important to feed the horses the right ratios of it based on weight. While not everyone in our barn uses this, I notice a difference in my animals' stalls. I vastly prefer this over fly spray and topical applications.

As usual, Chewy.com delivers things quickly and efficiently. I would suggest, however, with a product like this that you make it a bit easier to determine how much of the product should be given. I had to search quite a bit to find a chart to use.
Helps with Fly Control

Great product. Easy to mix in feed, horses eat it right up. Only will work if all horses on property are using it and no close neighboring livestock to attract flies.
Quick shipping, great product!

Thanks so much for getting the Simplifly to me so quickly! This is a very effective feed through fly control!
order included a damaged item
on Jul 13, 2020
My last order was for several items (the Simplifly was the order before). I ordered 2 fly traps, and one was defective. I mixed the solution, and went to hang the trap - the bottom was not attached as it should have been, and the solution all poured out. It is not fixable. I sent an email to you in regards to this, but have not yet gotten a reply. Otherwise the last several orders have been fine.
Not that great

Well all 3 of my horses have been on the product for over a week. I have the only horses or livestock for over a mile radius of my place, I pick up my manure from paddock daily, it is then hauled off weekly. I have saw NO difference in the fly population on the manure or in the storage trailer. I am disappointed, as I thought the flies would not be able to reproduce, but the tiny flies are abundant.
I cant believe this stuff really works!

Been using this for two months now and I have seen a very significant reduction of flies at our rescue! I will continue to use this product. It really works!!
didn’t work for my horses AT ALL

I have read the instructions gave them exactly how much they needed in their feed. But nothing is working we even had to put up fly traps all around their stalls because the flies are so bad, even turning the horses out in the pasture the flies are all over them even while giving them this food. Sorry it just does not work for me

I use this every year at my barn. This is the best price I have found with free shipping! Love the 50lb tub as it is hard to find... thanks Chewy!

Good stuff, just add it to their food. Has cut down on the amount of flies that are around them.
