Why do horse flies bother some horses more then others?

Question

I have a big bay mare that seems to attract horse flies more then the other horses. I have 7 horses in a pasture together and the for some reason this mare is the only one with nasty bloody horse fly bites on her! I can stand there and watch them swarm the herd and ignore the other horses, only to land on her! Why might this be? Any suggestions on how to change it? (outside of the obvious - fly spray - fly sheets) She's not an unhealthy mare - not underweight - or old - so eliminate those from yor answers! Thanks in advance for your help!

Answer 1

because they bite! ever been bit by one? hurts worse than a bee!

Answer 2

If your horse has more eye secretions or likes to roll in manure more than the other horses, the flies will be more attracted to her than other horses. Make sure that her eyes, nose, coat, mane and tail stay clean. Hope this helps. =)

Answer 3

I would try to hang up a fly trap by your barn or maybe at different places in the feild.  YOu may also be able to buy a fly rub thing.  I think that it is usually used for cows but you will have to read the label try a tractor supply if you have one or a southern states

Answer 4

um they have some horse spray and you should try to spray it on her and my horses get flys on them when they are wet or something im sure your horse is not wet so i was jus saying that ♥♥♥♫

Answer 5

Horse flies are usually attracted to horses that are more sweaty than others! When you ride a horse and it gets sweaty...a lot of things can make a horse sweaty but to help solve this problem make sure your horse is groomed, and brushed properly that way it will not have as many horse flies on it! Good Luck to you and your horse!
