I bought a pack of the magic dust, supposedly enough for ten hive treatments. Using an eBay sublimator for some and my copper block with glow plug for others I treated through the omf with the hot units sitting on damp hardboard. Pushed a hive tool into the joint between crownboard and brood box to check sublimate penetration then removed when wisping could be seen. A heating cycle of eight minutes for the eBay unit does the job or ten minutes for the copper block homemade unit.
All operations carried out from the upwind side of the hive.
