The Thermocell needs an attachment to convert it to a Thermoscent . It is a clip that holds the scent wick about 1" away from the heat . You put about 1 oz of doe pee or whatever scent in a baggie and put the wick in to soak it up . You then place the scented wick in the holder and turn it on . You can buy extra butane cartridges for about $5 in WalMart in the curling iron section ........
