Menthol pellets can provide some control of tracheal mites. A perforated packet containing 2 oz. of menthol pellets is placed in each hive in the apiary where tracheal mites are found. The packet should be placed on the bottom board during warm weather (80oF) or on the top bars when maximum daily temperatures are cooler than 60oF outdoors. As temperatures rise and air exposure increases, the menthol vaporizes and its fumes fill the colony. As the bees breath the vapors, the mites are killed. During cool or cold winter weather mite control with menthol is not as effective. It should not be used in a colony during the nectar flow because honey supers are being filled.
Fall: Begin the first menthol treatment and follow label instructions.
Two treatments, 21 days apart, are needed to get good results.
Apply vegetable shortening patties to all colonies.
Patties are made of 1 part vegetable shortening to 2 parts powdered sugar, and should be placed in the brood nest.
If no nectar flow is occurring, colonies should be fed a light syrup (1 part sugar to 3 parts water) to stimulate heavy brood production.
A large population of young bees will be needed for successful wintering
