Ive used the pink naf one which was rubbish also had a go at making my own that didnt work So this morning I've just brought some coppers fly stuff fingeres crossed it works!
I used the Nettex one last year which seemed quite good. This year I've bought their more expensive one, can't remember what it's called but it claims to work for up to 72 hours - we shall see! Not sure if that applies if horse gets very sweaty and has to be washed, probably not!
