I am new to gardening and we built a raised bed hoop house with plywood floors and then I filled them with purchased soil from home depot. I used the same soil in several outdoor containers as well. I noticed on the hoop house, there are TONS of these teeny tiny little bugs all over and in the soil. I hadn't seen any in any of my containers though. Are these good or bad and if bad what do I do to get rid of them? If good, are they harmful to humans or animals in anyway? I have a short zoomed in video but couldn't attach or post link. Please help.
