I saw the same article and thought I would give it a try this summer. Of course, that will still be 2 months away...
Does anyone have info on the concentration of HBH? I have the individual EOs (lemongrass, spearmint, thyme & tea tree). How much of each is in a pint of HBH?I mixed 1 tsp HBH into one cup of 1:1 sugar water, & poured it over my bee's. This is 4x the normal dose used too feed.
