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

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.] 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.
