Hi, I live in Malaysia our house have been invaded by these little creature recently. When it was one or two it doesn't matter, but then soon it reproduced at an enormous rate. Not sure what is their first form but they once these little black like caterpillar cocoon but it can move and then it evolve into these little flying bugs. I need help on how to get rid of them, the cocoon seem to like wet area and when it's ready to morph, it'll seek for dry land.
