Hello Ann, Hi all Seems it's the best way to use the beeswax from the 4 frames mostly contaminated with Apistan : to burn them in candles ... if the flame is quiet (don't disturb by any vent) the fluvalinate molecule will be cracked into elements and oxidized in carbon dioxide and water as the wax. Really you'll create some other molecules but no more than the usual burning candles. It's also the usual action of candle flames against the smokes ! Hope this helps ! Jean-Marie <[log in to unmask]>
