Blue has these things we get from the Co-Op that are little bands that you put right above the corronet, and they repell flys! They are GREAT! You can smell them from a mile away though! But they smell like fly spray, so I like it
If you are talking about the Fly Zone Bands I had a horrible experience with them. I put them on my horses just before vacation since we wouldn't be home to apply fly spray or to put their masks and fly leggies on. We were gone for 3 days and when we came back I was appalled at the condition of their legs.
The bands were ripped to shreds and they left a green caustic like substance on their legs. Terrible rainrot going on where they were too. The bands left a ring of crust that could only be shaved off. It was horrible and I felt so bad that I did that to them.
I believe it was the dew on the grass that did this to them. Perhaps if you lived in a dryer climate???
As far as those fly leggies go, I LOVE them!
Just get the better ones, not the real cheap ones. They don't stay up.
Can't go wrong with the brand name ones.
I personally like the ones that only have three velcro's rather than the four. Easier to get on and off.
They no longer stomp and that of course is healthier for their hooves/legs.
Before I got them I had a horse that would get an abscess each year from stomping. Since I have gotten the leggies she has never had another one!
One set lasts about 4-5 years. Even longer actually, I just get new ones so they look nicer.
So yes, I believe that the fly leggies are one of the best things invented for the horse as far as fly control go.
There have been occasions when the horses have gotten them off, but not often. Perhaps once a month. Not bad for wearing them everyday.
I also take them off each night.
