There's still a debate on exactly what these mites actually do as far as habitating (if that's a word).
I can tell you what my experience was.
They don't fly, they're too small for the naked eye to see. In fact at first, you probably won't notice a thing. A few days later a blister like thing appears, just like a chiggar bite.
You put chigger-rest or something like it on it, think nothing of it and it gets bigger and bigger and then there's a white dot in the middle and bubbles around the edge of the originating bite start to form. Those bubbles eat away at your skin, joining the originating blister-like bump.
They almost build cities like in a row or circle. They did it around my belly button. Then something under the skin connects those cities, like a burrowing. Then you get large boils.
Puss, infection, not fun at all. What's troubling is that mum's the word and unless you know someone, every place you go will tell you anything from a "Dermatologist" issue, to psychosis, even Scabbies.
Scabbies usually are found in the webs of fingers and toes and leave a hard scaley like fungus behind.
These are nothing like that, but I'm getting the feeling that mites, just like anything CROSS-BREED!
These leave bird nests after birds migrate in search for a blood meal. They're not picky either. Cover up in Autumn and take a shower after being outside in heavily wooded areas.
They disike sunny areas. Those seem to be o.k., but animals can track them into the home...
