Pardon me if this has been covered before, but I’m new and I can’t search.
When I was growing up, two of the houses we lived in had pools, which meant lots of concrete. I noticed that in both of these places (both in Ontario) there were hundreds of very, very tiny red bugs walking around on the concrete. They were smaller than the average flea. Very itsy-bitsy. I don’t ever remember being bitten or stung by any of them, but they were so small I may not have noticed.
I’ve googled them and have come up with the fact that they may be adult chiggers. I find this surprising, since I thought chiggers were usually found in high grass. Are they indeed chiggers?
