I keep finding these little red bugs in my home. They are very tiny, resemble a flea, and fly. So far no one has shown any signs of being bitten or anything, but I keep finding them throughout the house, especially on the walls in my bathroom (I also have them flying around in the living room). They are very hard to squash, just like a flea. I've googled images but cannot find anything that resembles them. Any idea what they are? A friend who lives in Bliss, NY said he is also finding them in their home.
