Formula 707 MultiFly Feed-Thru Fly Control Pellets for Horses - Palatable & Safe Fly Population Reduction (5 lb Bag - 91 Servings)

This stuff imo is the most effective at reducing flys around horses. Traps are good, spray helps keep the flys off horses, and feed thru reduces their numbers. I mix one level scoop in their feed and they eat it no problem. It looks to be made with alfalfa and the pellets are small. This feed thru works well and I will buy again.

Legit works!! I'd recommend this to anyone with horses who wants fly control. The product cut the flies in half, if not more. My horses seemed less bothered, and their tails looked better by the end of fly season with less swishing.

Something has to be out of this world for me to write a review and I will tell you this product is like a miracle product. The difference this product has made is life changing at our barn. I have BARELY any flies and my horses and goats are so much happier and less frustrated. It’s actually amazing like I didn’t not believe it was going to work,I bought this out of last minute desperation from the severity of the flies this year and it went far beyond my expectations. You won’t regret this purchase at all.

Been using this now 2 years in a row. Started feeding end.of March . As soon as I saw 1st fly. My barn is a fly free zone! You may see 1 or 2 flys bit thats it!.my farrier is also a happy camper when comes to our barn. I truly recommend this. Ww tried other feed through but none worked this well! Wish there was something that kills the May flys and deer flys that live in the trees and attack.you when your heading to the mailbox or trying to enjoy sitting by the pool since theres no poop for them to land on.

Wouldn’t be without this… I have no flies!

Took about a week to see the huge reduction in the fly population. I have chickens and cats was concerned about any pesticide harming them. I was not wanting to be putting toxic chemicals in my horse either. They have no problem with eating this on top of feed. Around the barn and pasture there has been a noticeable difference. I highly recommend it to my friends fighting the fly battle. On the trail I use a topical essential oil concoction to keep flys away.

Takes a few weeks to see results but dramatically reduces flies. It doesn’t eliminate them. Doesn’t kill adults or repel new flies but it stops larva from developing into adults. I’ve used it for a couple years now and it works better than anything I’ve ever tried. 90-95% reduction I would estimate.

Went through two full bags.. can't say we really noticed a difference at all
