Mike Griggs raised several very relevant points about the possible dangers of using fungi to control varroa. My undestanding is that IACR and HRI in the UK have identified fungi that will control varroa, but are now conducting extensive research into any possible safety issues and this is the reason that we are unlikely to see any products on the market for some considerable time. There is also the issue of possible methods of delivery. Much work to be done.
