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!!

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

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.

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.

It works for my purposes!
I cuts down on the fly population and is well tolerated by my horse. Cancelling subscription because product arrived and the lid had come off the tub. The product was loose in the box. I poured the pellets back into the tub and replaced the lid but it will not stay on so I will use the previous tub for a container. In the process, some of the product was lost and I am guessing the postoffice got to clean some up, too, as the tub is not as full as usual. I do not have time to send this shipment back. I will say that I have been buying this product for years and this has never happened before.

It works and is cost effective
It works. I’ll use it again next summer! I had a 95% reduction of flies with this and weekly spray down in my coops.

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
