Initial testing started in August 2007 and was overseen by a National Bee Inspector and a bee farmer in western Sweden. The aim of the project was to decrease and monitor the number of varroa mites. No other treatment was used on the hives, only a Bee Healthy Disk was present during the entire season. Each hive was fitted with a special grid to collect and count dead varroa mites falling down during the whole season. The annual treatment with oxalic acid was carried out at the end of the season, and any remaining varroa mites were collected.
A reduction in the infestation of varroa mite of 80-100% has been recorded. According to the National Bee Inspector who performed the tests the results were astonishing. They had never seen so few mites in any of their 75 hives before. The Bee Keeper says that he is confident that the Bee Healthy Disk works very well.
