Your cart is empty.When flies are a menace in your stable, it’s time to target them at their source – your horse’s manure. If not treated, the manure from one horse has the potential to produce tens of thousands of flies in a single day. Introduce SimpliFly Feed-Thru Fly Control to your horse’s daily diet, and suddenly you’re turning the favorite breeding grounds of stable and house flies into a No Fly Zone. When fed daily, SimpliFly Feed-Thru Fly Control breaks the fly lifecycle by preventing fly larvae from developing in a horse’s manure. This fly growth regulator is made without organophosphates and will pass through your horse’s body unabsorbed. The feed will instead excrete the active ingredient diflubenzuron into their manure, preventing it from being a viable breeding ground. This product can be effectively started anytime during fly season, but for best results, beginning daily feeding in early spring before fly season is optimal. SimpliFly Feed-Thru Fly Control is a highly palatable mixture that your horse will readily eat and easily mixes in with their daily feed. As part of an integrated, pest management program, you can see a significant decline in this season’s fly population. Keep your stable happy and target the fly problem at its source with SimpliFly Feed-Thru Fly Control. Bugs don’t fly with Farnam, your partner in horse care.

Everybody seems to love this. When I’ve used it by itself, I have not had much luck when I’ve used it in conjunction with another fly product like bug block or garlic it works. Better.They do eat it so it’s highly palatable

Saved this review until the end of summer for a honest and accurate description of the performance of this product.Works better than expected!This product basically eliminated our entire fly problem in the barn and around the property. We have experienced a 99.9% reduction in summer fly infestation. Started with this product in early summer and also used the giant fly paper rolls that worked equally amazing. The reduction in Flys is nothing short of miraculous and we highly recommend this product to anyone experiencing equine related fly issues. We live in Scottsdale AZ and it's generally dry around the property so the manure is the primary cause of fly activity.

I missed the boat getting this started in the spring- I thought I would just ride it out. The flies this summer however are so bad I figured it was worth a try. Within a week I saw the difference. The fly count was greatly decreased. Easy to use- sealing container with the necessary scoop.

Didn’t look at the weight like I should have. Thought it was a large Tub like I had bought in the past. It was very small for the Price $

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.

I have two standard donkeys and this stuff is amazing. Almost no flies compared to when I didn't use it the year before. You do want to start it early in the season so you get on top of the fly reproduction cycle before it gets too hot/wet, otherwise the battle to reduce the flies will take longer. I don't give it to them in the winter since we don't have flies then, but definitely start in early spring through late fall.

Simplifly is a pretty terrific product if you only have a couple of horses. We started feeding this in late February and have kept up through July so far. The flies are not totally gone but the amount of flies has been drastically reduced. We will likely use this product until after the first deep frost then resume again the following February. It is not eff3ctif you wait until the flies appear then try to get control from behind the 8 ball. Start early and keep it going throughout the season is the only way to go. We use a 3.5# bag every month, feeding two horses one scoop per horse per day.
