Ask the Expert: insects in my houseplants Hello, I've noticed an insect infestation in all of my houseplants (I think it started in one by a window, and has spread). The insects are small, dark, and fly. Their head is much smaller than their thorax, and they look tiny and thin. They are a bit smaller than fruit flies, almost like a flea, and though I see them flying when the plant is moved or blown on, they also crawl and run. I see them mostly on the soil surface. I can't discern symptoms with the plants (they don't maybe seem as healthy as before, but there are no holes in the leaves or anything). Could you tell me: 1. what these are? 2. how to get rid of them? 3. how to prevent them in the future? I tried taking a photo (I caught one in a bug jar), but it's really too small to focus on.
