A process for controlling parasitic honeybee mites, such as Varroa jacobsoni, Acarapis woodi and Tropilaelaps clareae, by the use of 2-(2,4-dimethylphenylimino)-3-methylthiazoline or an acid addition salt thereof, as well as novel compositions for controlling honeybee mites, which compositions contain these active ingredients. The active ingredients are administered in physiologically compatible preparations to the bees as feed or are applied in the beehive.
