Formula 707 MultiFly Feed-Thru Fly Control Pellets for Horses - Palatable & Safe Fly Population Reduction (5 lb Bag - 91 Servings)

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.

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. :)

We have a total of 9 horses and ponies. This product has almost completely eradicated the fly population in our barn and pastures.We can now enter our barn and we might see a total of 5-6 flies, as opposed to thousands. We can clean the stalls in a pair of shorts and not get bitten by flies.When we pick the manure from the stalls and clean them, there are literally no flies!This product really works! The trick is, do not miss a day of treatment. Also, every horse must be treated. We add it to each of our horse and ponies feed every night. They eat every bite. It seems to be palatable to them.We started using this product about a month before warm weather arrived.It’s so nice to go in the barn and not be swarmed by flies! I’m sure the horses appreciate it, too!

Works as advertised. We have significantly less flies when used with manure removal and some fly control. I would image little to no flies if we lived on a bigger property, we have very close neighbors that do not practice fly prevention.Easy to feed, my horses gobble it up. Overall, worth buying and I will continue to use.

Been using this product for a little over 2 weeks now. Where I'm located in AZ, the flies do not seem to be bothered by fly repellant, when they're sprayed they really just seem to shake it off and fly away! Hanging fly traps were full and tossed in a week. Thought I'd give this stuff a try. I can say that it has cut down on the volume of flies, they don't go away but there are fewer of them. This last batch of fly traps have lasted 10 days now and I will toss them in 3 days when the trash goes put out for pick-up.

Works great! Even though there are other horses in our barn and in the adjacent fields, the flies are noticeably less in our 3 stalls and in the field that only our 3 go into.

I have to say I'm a bit disappointed. Late year I started using this product and was amazed there were NO flies on the piles of manure I was shoveling. It did not keep the flies off the horses, but at least I wasn't adding to their procreating. This year, with a new bag of 707, flies are still in the manure. I thought perhaps since I stopped using this product through the non fly months, it took awhile for the product to be efficient but it's been 3 weeks. I will finish out the bag but wo improvement will not reorder.

It says to start it around spring before the flies get bad. However I didnt do that because I just found it. I ordered it in June. About the first 2 weeks I noticed less flies and now a month in and im seeing very few flies, sometimes no flies at all. Im very impressed with this because I have a horse that is sensitive to flies bites. He gets welts and they cause sores on him. This has worked so good for him. Ill continue to buy.
