Twelve semitrailer van loads of comb honey were treated with carbon dioxide for wax moth control. An average concentration of 98.6% carbon dioxide was held for periods of 10 or 12 hours, and the average amount of carbon dioxide used was 1337.5 lb. (0.52 lb. per cubic foot) per treatment. An average mortality of 97.8% of caged wax moths was achieved during treatments.
