Safe, simple & affordable fly prevention

  • Cyromazine, the active ingredient, prevents house & stable fly egg development
  • The overall fly population is significantly reduced within 4-6 weeks
Solitude IGR is an effective, safe, simple, and economical feed-through fly prevention that prevents house and stable fly development. Cyromazine, the active ingredient of Solitude IGR, safely passes through the horse's system and is excreted in the manure, regulating house and stable fly egg development. Solitude IGR is effective only against immature house and stable flies. As existing adult flies die off, overall fly population is significantly reduced within 4 to 6 weeks. Create a healthier environment for your horse. Cost-effective and easy to use; just add 1/2 oz into your horse’s daily feed regardless of your horse’s breed or size.

Active Ingredient:
(Maintenance Dose = 1 scoop (1/2 oz) daily)
  • Cyromazine (N-Cyclopropyl-1, 3,5-triazine-2,4,6-triamine)
Inactive Ingredients: Alfalfa, wheat shorts, and molasses (feed blend); mycocurb (feed preservative)


Instructions for Use:
Directions for Use:

Feed the reccomended dosage to each horse seperately to make certain full ration is recieved. This product is to be fed top-dressed on grain or mixed with the horse's total ration to provide 300 mg (1 scoop) of cyromazine per horse per day ir 600 mg (2 scoops) of cyromazine per horse every other day.

Start administering Solitude IGR early in the spring before flies begin to appear and continue administering throughout the summer and into the fall until cold weather inhibits fly development. In some cases, supplemental fly control measures may be needed in and around paddocks and stables to control adult house flies and stable flies, which can breed not only in manure, but in other decaying vegetable matter or silage on premises. Solitude IGR will provide a high degree of fly control and will give the best results when integrated with a well-managed fly control program which includes appropriate sanitary and management practices to reduce the number and size of fly breeding sites. Certain conditions around horse operations encourage flies and should be brought under control as an aid to fly control. These include: Remove old and / or wet manure from in and around your facility so that it cannot become a breeding ground for flies. Clean up feed and hay spills, as well as water drainage ditches. Reduce areas of moisture around your facility, especially around manure holding areas. A successful sanitary and management program may allow less than constant use of insecticides. This, in turn, should prolong the effective life of such agents. Daily dosage: Using 1/2 oz. scoop supplied with the product, mix one (1) scoop of Solitude IGR in the horse’s ration every day.

    Solitude IGR is rated 4.6 out of 5 by 76.
    Rated 5 out of 5 by from Last year, we moved our horses to our first family farm, so we started them on Solitude since it was the first time I had control over my own "herd", of 4 horses. I was coming from a nearby boarding barn where the fly problem was just absolutely horrific. Even though our horses were started on this late (in June), we had very few flies! So it definitely works, no question. I noticed, looking at the manure pile, that flies were still breeding in the manure somewhat, so it didn't stop them 100%, but I hung a Big Bag fly trap by the manure pile and it seemed to catch most of them before they could make it back to the barn. No problems getting the horses to eat this. Will be buying again for this season.

    Rated 5 out of 5 by from good product This is the second summer I have used solitude for fly control. My horses readily eat the pellets and it does decrease flies. I like that all horses receive the same dose - no worrying about how much the horse weighs or if you might have fed the wrong amount.

    Rated 3 out of 5 by from First time user of this product. I just started using this to see if it helps my horses this summer.

    Rated 4 out of 5 by from Easy to use! We are on our second bucket and I DO see an improvement in the barn and paddock - fewer flies! Yay!
    Date published: 2016-09-17
    Rated 5 out of 5 by from Consistently Works! I have used this product for at least 8 years and didn't use it last year. I never have a fly problem and last year was terrible. Started in March this year and no fly problem again.
