Does seem to be making my black horse less attractive to flies, took a few weeks to start working. Very palatable.

Only been using this for a short period but my TB doesn't seem as plagued by flies recently. Hoping with continued use things continue to improve

I’m still early days but so far it seems to be working! Less horsefly bites which are pretty noticeable on a grey! The only thing I’ve found with my fussy girl is I have to dampen her feed for her to eat it

I’ve used this for many years and it does help, there is no way my semi-feral ponies would cope with fly spray!

My horse is happily eating the supplement and it seems to be helping with the flies. Arrived very quickly and strong container

Just started this, but so far even the fussiest of eaters are eating it.

Has made a massive difference to my mare! The flies don’t like her half as much and she isn’t tearing her skin to spreads to itch the bites. I do have to give her 2x the recommended amount but worth it to stop her having fly bites bigger than my hand

Fly Formula is excellent at keeping the flies off. I can really see a difference when the horses are being fed it. Highly recommended

Super product, smells great and very effective. Before trying fly formula my mare ended up covered in hives. Now they are very rare and she is happy to eat this as part of her feeds.

This product is brilliant I have been using it for a couple of months. My pony had to have surgery in a “delicate place” it would of been impossible to fly spray it the vet was amazed we didn’t have fly strike. I can only put this down to good husbandry and this product!

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.
