Our youngster was struggling with midges by the river.  It does take a few weeks to work but now so much better and not even wearing a fly rug anymore

My horse is extremely sensitive to the flys, started the fly formula early to get it in his system, he doesn’t seem as stressed and bothered by them, have ordered my next tub!!

Thanks again for another fab product Feedmark.

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.

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

Blanca had Fly Formula in Spain, taken over in my suitcase… Worked a treat. Now living in Wales I’ve added it again to her feed to prepare in advance for the fly/midges season to help her to again build up immunity from needing to scratch her mane off!

I think this is a good supplement, doesn't keep all the flies away of course but I do think my ponies are less bothered by them than the others on the yard.

Have used this for over 12 months it helped with flys in the summer. It also smells so nice it encourages my fussy mare to eat her additives. I have been very pleased with this product.

I have used fly formula for several years now and it has definitely made a difference to my horse that has a terrible reaction to fly bites . It doesn't eliminate the problem completely but has made the problem much easier to manage . I tried him for a short period without and his reactions became much worse so put him back on it and things improved immediately which is why I gave it 5 stars

Fly Formula has changed our lives over the last 2 summers, as the ponies have been able to live without constant itching. Almost no scratching and mutual grooming which resulted both used to result in skin sores.
