Sandy looking teeny mitesi

[Bleenie]

I tried to find it online but couldn't. Someone here had told me the name before but I forgot
My new rooster had bad mites when I got him. Treated him with Ivomec and then followed with sevin dust. Well he's got them again and I can't recall the name of them and I'd like to treat them correctly and get rid of them!
