2. Varroa mites are the number one killer of honey bees globally.
3. A simple, effective and accurate method for treating varroa is the alcohol wash method.
"The test is carried out as follows:
- Use a wide-mouth glass jar and scoop about 300 bees (~1 cup) from the brood area. Make sure that the queen is NOT included!
- Add 50 ml (~ 2 oz) of windshield wiper fluid (or diluted methyl hydrate, or rubbing alcohol) to the jar and shake for several minutes.
- Remove lid and pour contents into a container covered with light metal wire-mesh screen (8 mesh/in) or a coarse sieve. Repeat.
- Pour alcohol solution into a second container covered with cheesecloth or fine sieve. Count number of mites." - Agricultural Factsheet #222
Do varroa mites only prey on bees? Or do they also go for other insects? Possibly ants?
