Thymol is not approved for the treatment of Nosema. Not only is thymol ineffective against Nosema whether prophylactically or otherwise but it can taint any honey that is on the colony. There are very strict food safety guidelines concerning residues in honey and the Food Standards Agency take a strict line. If your colony has Nosema, or if you have a weak colony that you think may have Nosema, then the best thing you can do is get them onto clean comb. This is best done by the version of the Bailey comb change for weak colonies. This is best done in the spring. - Margaret Murdin, BBKA President
