And this is a BIG MAYBE?
I don't have a big issue with deer flies and the black horse flies to begin with.
I'm not sure this works or if it's just that I'm not seeing any deer or horse flies this week.
I've been spraying my rainrot prone horse with a 60:40 mix of original Listerine:Water on his top line and rump. Actually I've been soaking him after I brush him.
I noticed he wasn't coming in with any bites on his back - from anything and it made me wonder if, by soaking his back with the Listerine mix I was masking his odor and keeping the flies away.
I know black horse flies are attracted to dark moving objects, which all my horses are dark, but I still wonder if maybe the flies are able to also pick up odors and the Listerine scent is confusing them, so they don't land on the horse?
I've been spraying the rain rot prone horse for over a week. The epiphany didn't come until this morning, so I soaked the backs & rumps of the other horses after I brushed them.
Except for sweating half to death in this humidity, I didn't see anyone having hissy fits over flies, so I'm going to keep using the 60:40 mix until it proves me wrong and I've wasted my time.
WalMart's "Equate" brand of original Listerine is only around $3 so it will go quite a ways when refilling a spray bottle.
I really don't know if this is wishful thinking or I've stumbled onto something - just thought I'd pass it along, since it's a cheap and very harmless fly repellant experiment.
Wouldn't it be something if such a simple thing as masking the odor of the horse kept those chain saw nosed flies off the horse.
I know this mix won't keep ticks off and I have no idea if it will work for mosquitoes as we don't have a big skeeter issue and my horses come in at night anyway
And the rain rot? For other health reasons, I'm afraid to feed him Vitamin A, so also by accident, I washed his back only with Dawn Dish soap the other night. He doesn't have any scabs, just what I call black dirt-mold and the Dawn Dish soap got rid of all that
Washing the entire horse in Dawn Dish soap is not something I'd do but I'm not opposed to washing this fella's back and butt with it, once a week.
I also use Dawn Dish soap to get the gummies off their legs from that miserable Dallis grass we're plagued with.
