What is the best treatment for Varroa mites?
The most popular essential oil for varroa mite control is thymol (from a thyme plant).

In most cases, an early Spring treatment may be necessary. This gets mite loads down before the honey flow begins. Monitor mite levels during the season until mid Summer. If not required before then, a mid-late season treatments lowers the number of mites and allows the colony to raise healthy bees for Winter.
Does varroa mite affect native bees?
Varroa harm the bees both by feeding on the developing and adult bees but also by vectoring viruses while they feed. In our area, if beekeepers do not manage their colonies to reduce mite levels, there is a 90-95% chance the colony will die within 2 years from effects of the mites and the bee viruses they vector.
Do wild honey bees have Varroa mites?
It is well known that Varroa destructor mites are one of the honeybee’s (Apis mellifera) worst enemies. Since Western honey bees do not possess the defense mechanisms to fend off non-native parasites, the mites can transmit deadly viruses to the bees.

Thyme, savory, rosemary, marjoram, dillsun and lavender essences at concentrations of 2 and 1 g/100 g (w/w), caused a mite mortality rate of more than 97% and 95%, respectively. Also spearmint at 2 g/100 g was able to kill more than 97% of Varroa mites.
Does powdered sugar work for varroa mites?
Dusting of powdered sugar is done in combination with the sticky board or a screen bottom board. Powdered sugar does not kill the varroa mites, but causes the mites to drop to the bottom. If there is not a sticky board placed on the bottom, the mites will crawl back up to reinfest.
Do varroa mites affect honey?
