Excellent product!
Last year, it was a fly nightmare around the house. Every time we opened the door, flies inundated us. I read about this on Amazon to try and find answers to a solution. I’m amazed at the difference it has made, and it is so easy to use! It lasts a long time even though it is used everyday in my horses feed. The door doesn’t have multiple flies covering it, just waiting to get inside, and I don’t have to spray my horse with fly spray as often. It is well worth the money. It keeps the fly eggs from producing in the manure. It’s amazing how well it works. This is the first season we have used it, and it will be a permanent product for our horse. It must taste great, because there is not a drop of food left in her feed pan ever! She is a picky eater, so it must smell appetizing to her. Great product! I highly recommend!

Fantastic Fly Control Supplement!
The Formula 707 MultiFly Feed-Thru Fly Control Pellets have been a game-changer for my horses! Iâve tried several fly control methods, and nothing has been as effective as this supplement. After just a few weeks of use, I noticed a dramatic decrease in the number of flies around my barn and pastures. My horses are so much more comfortable now and not constantly swishing their tails or stomping their feet.The best part? They love the taste! I mix it in with their feed, and they eat it without hesitation. Itâs great knowing theyâre getting the fly protection they need without any fuss. This product is safe, easy to use, and actually works. Highly recommend it to any horse owner looking to keep flies at bay!

Works!
I’ve been giving this to my pony and donkey (half dose) for two full weeks and am already noticing the lack of flies on/around their poop. My chickens scratch around in their poop and there’s been no problem for them either. My pony and donkey love getting their “medicine”- tasty! So far, so good.

Unbelievable results
To say I was sceptical is an understatement, I was desperate for a solution to the flies in the stall and barn area. Using fly spray with chemicals on my horse wasn’t what I wanted to o tried natural spay… I was out there 3 or more times a day. My horse has a fly sheet and fly mask and he was still miserable. It was an unreasonable monsoon summer here in New Mexico. I did some research and found this product to be highly regarded be horse owners with great results.My horse had no problem eating the grain formula. He’s food driven! Within 2 days I noticed I wasn’t fighting as many flies when I went out to feed and water and clean the stall. Within 5 days it was very noticeable that the flies were significantly less. Mostly in the manure I needed to pick up. My horse is happier, not having to fight the flies to get to his grain bucket!It’s worth the money and… It works fast!

Shoo Fly
I gave this to my donkey late in the (fly) season last year. I tried other products with mediocre results so I was pleased when this worked right away. I mix it with a small amount of grain but I think she’d eat it right out of my hand, if necessary. My second bag busted a seam and the top does not seal well, contrary to the first bag that did not present any problems. I taped up the seam and I keep the bag in a sealed container, so not an issue, but maybe the manufacturer should be aware. I will continue to buy this product.
