Farnam Simplifly with Larvastop Feed Thru Fly Control, 20 lbs.

Simply mix into their feed. The horses don't mind it at all and amount of baby flies in droppings appears to be greatly reduced.

You need to start feeding in early April and feed every day without missing a dose so the flies have no feces that doesn't have the larvaecide in it .

[This review was collected as part of a promotion.] We have used this for all the horses for 3 years and each year we have fewer and fewer stable flies. Horse flies and deer flies will still be an issue but any fly larvae that depends on manure will definitely be reduced. A bit expensive but the barn is so much better without the flies.

I have been using the Simplify with Larvastop along with fly predators this summer and am amazed at the difference it has made in the fly population around my barn and in my pasture. Of course there are going to always be those flies that come in from neighboring properties but I have confidence that their ability to leave this world with offspring is greatly reduced once they make it to my place! Bottom line, the Simplify with larvastop may seem a bit pricey but when you figure in the cost of less fly spray it is well worth it. I purchase my fly spray by the gallon and still have the same gallon I started with in the spring and that speaks volumes with 7 equines.

[This review was collected as part of a promotion.] I've been using this for years and it really helps. You do have to give it to all horses on the property for it to be effective, so it works great for a small barn. My horses don't seem to mind the taste and it truly minimizes fly issues with stable flies.

[This review was collected as part of a promotion.] Flies were worse this season than usual--our vet recommended trying SimpliFly-- great price & service with Santa Cruz Animal Health--it has helped with our fly problem--and the horses eat it with no problem--great product from a great company--

Simplify has always been my "go to " feed through fly control! It's best to start it early or, if you're like us who live in Florida, stay on it year round. It is a big help with flies but other measures may be needed too, like a perimeter spray. . . I love the prices from Santa Cruz and of course, their free shipping !

We have been using Farnam's Simplyfly for 2 years. It definitely makes a difference in the fly population. You should follow the instructions and feed the correct amount every day. We started using this a little earlier this year because we had such a mild winter and it has reduced the number of flies we see. This is an easy addition to any fly reduction program. I rarely have to use fly spray to keep my horses comfortable and fly free so the cost is offset by less need to buy multiple bottles of mostly ineffective fly sprays.

[This review was collected as part of a promotion.] Simplifly works better than the fly predators we used previously, however we still have a lot of flies at our barn. We clean up our horses' manure twice daily and hang fly strips to lessen the amount of flies. We start Simplifly late March, before fly season, and continue through autumn. Have found no product that adequately controls flies.

I started my two horses on this at the beginning of March and the flies are still awful. I was hoping to avoid the use of fly spray but they would have dozens of flies on their legs. I've now started Fly Predators and Bug Check and will finish off the bucket I have of this but I don't think it made any difference at all.
