What is eating my horse skin?

Okay I know flies can cause damage but we don't have an abundance of flies and two of our horses have shown signs raw areas. Mostly on their heads.
We had taken our old gelding to the vet two weeks ago before the flies even began and he already had this going on. The vet suggested flies but said it was unlikely since they weren't even out yet. We were left without an answer since that wasn't the only reason for the visit.
Then I brought home a new horses and the same thing happened within a week. What is it? We do have Oak trees, and tons of Chamomile in the pastures. These two horse are not kept together. I applied swat a couple of days, and then corona today, put on their fly masks, and spray them down with spray. They are healing, but i want to know the cause.
My new horse has it on the skin under his flank, and throat too.

The areas are relatively small. Around the eyes, down toward the norse and then small patches under the flank etc. Our old gelding, that we took to the vet, is also suffering hairloss at the top of the tail and a spot on his mane too. We dewormed him again according to vet's advice.
I ordered some Zephyrs Garden Anti-Fungal Spray and
Calm Coat All-Natural Topical Spray from horse.com. I researched mange treatment and came up empty handed. I pray it's not that!
I can try and post pics tomorrow afternoon.

It could be a fungal infection. It also could be mites that came from birds and are irritating your horse's skin, causing him to rub and itch on things, which in turn rub out his hair. This happened to my mare on her face, and I just washed her thoroughly with an anti-microbial wash and made sure to keep her extra clean. Whatever it was went away quickly, and I put some cream on the rubbed spots and they healed quickly, too.

Some cats have a high metabolism.I have a twenty-one year old Siamese who does nothing but eat and has always had a long and lean profile.And outside cats that are especially active.If however,your cats' eating behavior has changed recently or it's stomach is unnaturally distended, you might want to check with your vet office(sometimes calling on the phone can save you a vet bill) and get your cat an over the counter worming medication.Sometimes though an office visit is unavoidable,if parasites show up in the pets waste.

A picture would be handy, sorry I can't really help without more detail, there are so many things. It could be ringworm, a type of mange, a fungal infection, an allergic reaction ect. If youpost a picture I might be able to help more, or even let us know how big the sores are? And how many? And where?

There are a number of things, but I can't help without anymore detail sorry.
