That doesn't mean much lots of insects fly. Eg gnats thripes native bees etc. I think it's thripes they hate need oil. Leave little holes on your plant.
Yep, its Fungus Gnats. Try picking up some diatomaceous earth and sprinkling it on top of your soil.
If this doesn't clear it up, i have found great success in Mosquito Bits. If you google just that, "Mosquito Bits" it will come up immediately, I use that to sprinkle on my soil, as well as anywhere i have standing water within the grow area. This finished off my gnats completely, i highly recommend it.
