Bug issues

Bug issues

There are these tiny little gnats things flying around my orchids. I don't see them around any of my other plants. They've been there for a few months, but they don't seem to be going any damage. I'm scared to spray pesticide on my orchids... would that be okay? Are the bugs even something to be worried about? If not I'll let them live there. I don't really care. They stay over there I don't see them around the house. They are starting to multiply. There were only two or three about four months ago... now there are over five. Thanks!
