I'm growing tomatillos, and this very very tiny red bug has shown up. It seams to be harmless, but is anything harmless? It's too small to get a photo of it. It barly looks like a bug at all. It looks more like a flax seed, but smaller. It does have texture to it that makes me think it is a bug, and more keep showing up. They don't seam to move. They don't seam to react to my chili peper/garlic/neem/soap spray, and they are pretty eay to brush off, but I don't want to just brush them off into the soil or grass to have them make there way back.
Any ideas of what they could be?
