Review: It Works! I’ve Used it Two Years in a Row. - I’ve waited to write a review for this product until the weather was consistently warm (and flies were likely to go after my horses.) We began using this in February and it has worked incredibly well. It is now mid-June and we have some flies in the barn, but they are about 90 percent less than last year and they tend to congregate around the muck buckets instead of the horses. I have tried so many fly treatments (i.e. fly spray, fly masks, fly boots, permethrin, etc.). This product works. The key is to put the supplement in the feed about a month before flies will appear. If you wait until you’re under attack by flies, it won’t be as effective (we also used it at the end of last summer and the result wasn’t as good as being proactive / starting early. It still helped but this year has been much better. My horses still wear fly boots, but we only put fly masks on when they are outside and the flies are going to find them anyway. The flies in the horse barn were intolerable last year and that’s not the case at all this year. The horses get a few flies but nothing major. The product is outstanding. I highly recommend this product. It has helped reduce our fly population so nicely and the price isn’t crazy. You honestly save money by purchasing this instead of using five other fly repellents to get to a lesser result. My two horses love the flavor and have no issues with this supplement. Thank you for solving our fly nightmare. :)
Review: Worked great. - Best fly control we have had in years. Zero flies is unrealistic but this stuff helped keep them to a minimum. Easy to use. Worth the price. We have already purchased more and plan to use next summer, too.

## Questions & Answers

**Q: My dog eats manure. Will my dog be safe if he consumes manure when I am feeding MultiFly to my horses?**
A: We have many MultiFly customers with pets that like to eat manure. However, we are not able to make any claims regarding safety/efficacy for any other animal other than horses.

**Q: Can I feed this to other species (cattle, goats, chickens, dogs, etc.)?**
A: Novaluron (active ingredient) has been tested in non-equines (e.g., cattle, goats, etc.), but we are not able to make any claims about safety/efficacy for any species other than equines. Please ask your veterinarian.

**Q: Does MultiFly repel flies from my horse?**
A: No - MultiFly is ineffective towards existing adult flies. MultiFly is not a fly repellant - rather it is an Insect Growth Regulator that stops flies from reproducing in manure.

**Q: How quickly will I start seeing results with MultiFly?**
A: Some of our customers start seeing results in as little as three days, but most people see significant results in two to four weeks, since that is around the average lifecycle of a fly.

**Q: I have a smaller/larger than average horse, how much should I feed?**
A: For the average equine at 1100 lbs or less, feed 1 scoop daily. For especially small animals (e.g. 550 lbs or less) you may feed half a scoop. For equines over 1100 lbs, feed 2 scoops daily.

### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ No More Flies. Period.
*by J***N on July 15, 2025*

I honestly didn’t expect this to work as well as it has, but wow—707 MultiFly completely delivered. After just a couple of weeks, I noticed a huge difference. The most impressive part? There are literally no flies anywhere. None. I’ve tried so many sprays and traps over the years, and nothing has worked this effectively. It’s simple to use and doesn’t involve coating your horse in chemicals or dealing with messy applications. Just a daily scoop, and you’re done. I love that it works from the inside out—targeting the problem at the source, not just temporarily pushing flies away. If you’re tired of the constant fly battle every summer, this is absolutely worth trying. I won’t go without it now.
