Fly Formula™

This product is the best repelent ever. I keep my ponies with me at home and we live in the middle of a wood. Before fly formula i was trying everything and nothing really kept the flies, midges, wasps, and all the insects especially horse flies which are enormous where we are but although still a slight problem with this formula they are much reduced around the animals.
When they take it internally the pores of the skin evaporate the smell i think and they stay away. Thank you Feedmark for solving my problem. **

I’ve used this product over 20 years and it definitely helps by greatly reducing the scratching and rubbing of the horses when this supplement is included in their feeds

I have used this product for 8 years. It has helped my horse with his skin condition as well as the summer months.
My friends have commented on the flies while out riding that they are on their horse but not mine. I swear it’s because of fly formula.

Ponies happy to eat it,always a bonus and they have less flies on them than other nearby horses.

Palatable and horse is enjoying it..early days to tell if it's making a difference but confident as with all feedmark products it does what is says on the tin!

I’ve used this in the past and it has been very effective. It smells wonderful and the horses love it. Now the weather is turning warmer I’m going to start using it so that it gets into their system before the flies arrive in force! Would recommend anyone to give it a go.

I’ve used fly formula for a number of years from spring to autumn. You can really see the benefit compared to those not on it

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.
