It does knock them down considerably though. Moisture has a lot to do with their proliferation. I'll probably give it a shot again in the spring or summer when they start flying around and everyone else complains. I did try one other treatment, but didn't follow through on it, so I can't post anything constructive about it.
Speaking of changing the potting medium, I do seem to remember that is how I got the little buggers to start out with. I bought someone's special premixed orchid media...complete with hitchhikers.
Keep in mind that the bug that I am talking about may not be the same bug you are talking about... a picture?
