I've read that the varroa do NOT like coriander. Since corriander is actually the seeds of cilantro I wonder if you could use coriander seeds or oil (does it exist?) inside the hive to help drive them (varroa) away? Maybe spray some coriander oil on the inside of the boxes or along the edges of the frames? Has anyone tried this? I can't find anything to tell if it would affect the bees or the flavor of the honey... Maybe plant cilantro around the hives?
Has anyone found any other essential oils that help with pest control? What are you using, how often and is it working?
