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!

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!

We have used this product for years, and I was thrilled to see I can buy it from Chewy.com at a good price and with free shopping when I combined with other items for my dogs.
