    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!

    5.0 out of 5 stars Fantastic Fly Control Supplement!

    The Formula 707 MultiFly Feed-Thru Fly Control Pellets have been a game-changer for my horses! I’ve 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. It’s great knowing they’re 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!

    I was thrilled to find an affordable product that works for my horses. I have two and they both get this supplement daily. They like the taste and I have noticed a reduction in flies this year. Thank you!

    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!

    I run an equine therapy program, and the flies were so out of control this year that the sessions were becoming unenjoyable, so I desperately searched for another fly control device as I’ve tried multiple others. The vet gave the okay on this and within ten days the flies were practically gone, and like I mean gone. A few here and there, it’s mind blowing. The vet said it was totally safe , def consult with your vet first but this stuff has made life with horses so much more enjoyable :) you do have to put it in their food everyday. I will be doing so until winter comes!

    5.0 out of 5 stars Cuts down on stable flies
    Reviewed in the United States on November 5, 2024
    been using this for all four horses daily and it has cut down on the flies to almost non existence. Follow recommended amount on container for amount to feed. I put it in with the horses grain 1x daily, it looks just like alfalfa pellets, and the horses eat it up. Would highly recommend this product to anyone with horses and flies.

    3.0 out of 5 stars Short-lived success
    Reviewed in the United States on August 13, 2024
    It worked initially and I definitely thought I had fewer flies in the barn however, now it doesn’t seem to be doing much. I don’t know if the flies got stronger or what but I was trying to reduce the spray I used in the barn but it hasn’t been helping over the last month or so. I’ll be looking for something else next year.

    The flies were horrible this year. I had tried multiple products and as a last resort tried this feed through. I was a bit skeptical, but it really works!
