Help with mange/mite and or flea diagnosis of a wild baby?

[LucyV]

Hello. My wild, rock squirrel friend is struggling with some parasites. He's really young, but I am not a squirrel expert so don't know how young. I am guessing he is 10-12 weeks old. I don't know what is eating him, but he is very scratchy and he's losing hair. Most hair loss/tiny scabs/spots are around his ears. There is also a dot on his nose that reminded me of bot fly?? (I keep domestic rabbits so I know a little bit about that).

Can anyone help diagnose from this pics? One is whole body pic (for reference) and the other is the close up of his face.

I read here some of y'all help the wilds with medicine, so thought I'd ask for some advice.

Thanks!
