I live in the Great Lakes area. I've been working out in my yard for the last month tearing down my old, rotted fence and putting up a new one. I have acquired a couple of mind-numbingly itchy bites. I assumed they were just mosquito bites - the first ones of the season are usually particularly bad - but I'm not so sure. Now I'm wondering if they're chigger bites. I've been reasding up on them. I got one on the inside of my forearm and another in the crook of my leg - both very soft spots. They are very itchy, and last a long time (a week or two) and the swelling is broad and flat (~1/2" across) but no blisters. We do have lots of little "red spider mites" on my property, but I'm not sure if these are harvest mites or not. They are bright red, about .5mm across and run around all over everything very fast. They sure look a lot like harvest mites from pictures, I'm just not sure they're the same thing. If I understand correctly, it's not the adults but the larvae that do the biting, and they're microscopic in size. Anyone have any ideas?
