And hey guys, this method works like a charm and will also rid tanks of mites(or any other bugs) even if nothing else works. It can save you from having to throw away your favorite tank accessories, including pourous wood, or delicate silk plants, without the need to boil. Works best if the tank is covered because as was stated, it's the "smell" that kills the bugs. All that is needed is to air it out, and no trace of poison is left behind.
