"Crusties" in mane?

So my gelding often gets these weird "crusty" globs on his neck. They really gross me out! I usually pick them out with my fingers and a fine toothed comb. I don't know what they are! They are round and "grow" on his neck and that's it. I also found one on my barn owners gelding.

What is it?!

That could be the result of him having bot fly eggs (you know the little yellow things he gets on his hair). When they hatch, they imbed themselves into the horse's skin and cause sores which in turn cause the "crusties". You might want to get a good fly repellant to use during egg laying season (august and september) and if there are any eggs that do end up on him, use a scraper to remove them before he has a chance to injest them because they are intestinal parasites too.

My guess is tick bite sites.

My dog had those in his coat. It turns out they were the result of allergies.

If they are bot fly eggs, you can use a slick n easy block to get rid of them also.

Hm, not sure what they are, but wouldn't hurt washing his mane with an anti-bacterial soap, made for horses of course. I'd personally use 'Quit-Itch'. It works really well, heals things great and stops itching (obviously)! Good luck.

My horse had those the first yr I had him. They were some weird bacteria thing. Im sure that is what you have, so I would try an anti bacterial shampoo. I think I used iodine shampoo and it worked in a week or so...hope this helps!

Splash gets these yellowish crusties in his mane. Are those yellow?

It could be a samll, black gnat called coulicoides, that causes these serum crusties. Here where I live, we have a problem with them in the early evenings. They are about the size of no-seeums and really work on a horse. Usually in the mane, ears, forelock area, the skin on the inside of the back lesgs, etc. About all you can do is either stall the horses in the eveining and / or use a lot of good fly spray.

Yes, they are yellow. I think the only answer on here that is probable is a tick biting site. I did find some ticks in or around the area of them. I've tried to thoroughly wash the neck/mane but they just come back. I will try something more "antibacterial".

Thanks everyone! Keep more answers rollin'.
