Fly Formula seemed to work well last year, but I remained sceptical. Well, the answer seems to be YES, it's working! After many years of coping with four itchy Shetlands, they are again looking good, so it must me the Fly Formula magic!

Been using fly formula for several years and my horses have far fewer flies around them than other horses on the yard. Excellent for hacking too.

New to this but no complaints so far :-)

I have used it for many years even though some people say garlic is bad horses?

Started the fly formula ready for the summer season…horses eat it without problem…hoping this will help keep flies away when the time comes…

Been using this regular since August and it does help.

Nothing is perfect with flies but they definitely had less on them than those not having the Fly Off. Used alongside whichever spray the flies are repelled by this season it’s a godsend.

Nutrition Information

Fly Formula™ is an oral fly deterring supplement, designed to reduce irritation from flies. When ingested on a daily basis, the pungent aroma of the ingredients passes through the skin to discourage flies.

Garlic granules contain a Sulphur compound, which is secreted through the skin. Insects taste via their feet, and those landing on the horse dislike this Sulphur, and so are less likely to bite the horse. The added Fenugreek seeds potentiate this effect, and along with other aromatic herbs known to be disliked by insects, such as Lemon peel, Peppermint and Rosemary, help to repel unwanted attention. In addition to this, ingredients that optimise skin health, such as Chamomile, Nettle, and Linseed help to soothe any areas affected by pesky flies.

Composition

Garlic granules, Micronised linseed, Mint leaves, Rosemary leaves, Lemon peel, Chamomile flowers, Fenugreek seeds, Nettle leaves, Peppermint powder.
