Hello There, I do not know where they all came from, maybe from the potting soil, but it is no longer beautiful. If you imagine a cup of coffee now and drinking this not in a drink from, bathe certainly some of the mini fly it. If you're lucky, you can fish them out alive. It had what happened !!! I ordered this yellow plug and distributed them in the whole house. In no time, they became meeting places for mini flying. It still flying around that, but it's not as annoying as before by far. I have the yellow plugs helped and I can recommend it with a clear conscience. LG Claudia
