I'm wondering, in my reading on mite treatment it seems that, and maybe I'm way off, that the main ingrediant found in a Apistan is Fluvalinate, a synthetic form of Pyrethrum called Pyrethroid. The natural form which is found in some species of the Chrysanthemum. These flowers have been known as beeing natural insecticides. Maybee it's a crazy idea, but I wonder how a nice patch of the flowers would work as natural mite control. Regardless, I will be planting some around my hives.
