## Overview

Farnam Simpli-Fly Feed-Thru Flies Control is a 10-pound pellet designed to prevent the development of house and stable flies by breaking their life cycle with larvastop, an insect growth regulator. When added to horse feed, it reduces fly populations by up to 100%, offering a highly palatable, easy-to-use solution for long-term fly management in equestrian environments.

## Description

Prevents development of House and stable flies in Contains larvastop, an insect growth regulator that breaks the fly life cycle manure when horses are continually treated.

Review: 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.
Review: 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.

## Questions & Answers

**Q: How long does 10 pds last one horse?**
A: 10 pounds will last about 4 to 5 months per horse.

**Q: how young of a foal can be fed this please?**
A: We recommend first consulting your vet. Simplifly should be fine for foals that are 300 lbs. or more.

**Q: Why can't this be shipped to calif.  Always ordered and now it says it can’t be shipped to calif.**
A: Must be some kind of new regulation, I was able to buy it the last time I ordered it.

**Q: Why not feed to "horses intended for slaughter?" Also...who raises horses intended for slaughter, anyway?**
A: correct if the horses are intended for slaughter and are supposed to be shipped from the  USA to Mexico for slaughter (horse slaughter is illegal in the USA) then these horses not only cannot have had certain vaccinations but they also cannot have been treated with various substances to prevent flies and worms. As to your question who raises horses for slaughter, plenty of 'breeders' in the USA do that but they would never admit to it. You can research for example the different registries for horses and draw your own conclusions.

*by D***G on 13 August 2025*

Awesome product. 2 weeks after we started using it we noticed the flies were gone. Saves a lot of money and hassle of using fly spray daily that never really worked. For us it reduced our on farm fly population by 95%. It's wonderful be able to be outside around the horses and yard, and don't forget the barn without the flies attacking us all the time. It also pays for itself by not buying gallon after gallon of fly spray.
