This summer/fall I noticed that on particular days, the flies seemed to be noticeably bad on my horses, which is normal - but they'd be all over their faces, in their eyes, etc. I don't want any diseases or problems, so I purchased a brand of Pyranha fly spray - which was recommended to be for being a little stronger, longer-lasting product, especially for the show season.
However, I haven't really had much luck with it. I don't spray it directly on their face, so normally I'd spray the fly spray on a soft brush or towel, and then brush it onto my horse's face. It'd work for like 10 minutes, and then the flies would be back.
I have considered getting fly masks, but I have three horses that would need it and I've only noticed the flies being terrible every now and then.. not constantly, if that makes any sense? I just want to try any other tips and whatnot before I invest in fly masks, which might get a little expensive for how much I'd use them.
So, in a nutshell, does anyone have any certain tips/tricks you use to keep flies away from your horse's face? Any brand of fly spray especially good?
(Oh, btw, I forgot to mention - my horses are in pasture 24/7 except for weather conditions; they do have access to indoors at all times also. I'm not really sure if this makes a difference?)
