Worth your money!!
We gave this product a try for the first time and literally don’t regret it at all. Within a week and a half to two weeks we noticed a difference for sure. We just do one scoop a day in their feed. Great product overall, it’s my second time ordering this and instantly noticed the effect of it. LITERALLY LESS FLYS in the stables for sure. Highly recommend it!!

It works!
We love this fly preventative and so does our livestock. No pill to take just some pellets to add to their food ONCE a day. It must taste yummy, because my horses and Donkeys love it. Flys seem to less too. I highly recommend SimpliFly

It works!
I was very skeptical since the equine industry is full of “snake oil companies” but I started feeding this out since April and as we enter July I’ve hardly seen any flies. Will definitely keep this on my regular schedule.

Works well
Cut the flys down quickly. Should have used it earlier in the year.

Don't expect 97-100%, but it does help
My first season trying this, having started in April. It's easy to use, the horses like it, and the fly population is noticeably down from years past. Nothing out there will totally eradicate flies - you'll always have them if you have horses. So it's nice to find affordable products that help control them, and Simplifly certainly does. However, the company's claim of 97-100% effectiveness is ridiculous; I would estimate that it's around 50-75% for us. But to me that's enough to make it worthwhile, especially in conjunction with other methods (fly bags, masks, occasional spraying). Our two horses went through a ten pound tub in about 2.5 months, so at a cost of $70 this stuff is approximately 15 dollars per horse/per month. For us, the reduction in flies easily justifies the cost of this product.

IGR not insecticide.
Works on house flies and stable flies. Works really well too. Gnats and horse flies nope. Gnats still are in abundance though maybe have declined but seems they are persistent. Quite possibly has knocked down the gnats. This is all I really see covering the horse manure so I’m hopeful that several season/ years of this will steadily drop their numbers. Summer of 2025 has been our first try of this. And we started late in the season to see a noticeable difference in the house and stable flies. Will probably stop feeding come first frost in NC here and stock up for spring and summer. Highly recommend.
