Yeah, mites can be pests down south where I used to live, but never were more than that.
If you really need a bug or two to be scared about, check out the Japanese Hornets, Bullet Ants, and Bot Flies. Those three form the axis of evil in the bug world.
lame as *****... that looks like ANY random mite colony, nothing amazing about it... go down south and youll see all sorts of this *****. and a lot worse. these things will have NOTHING to do with animals or humans, they just like new growth from algae to large plants and shrubs.... u thinkbeetles r bad... south has some NASTY bugs
