Here, in the Czech Republic we never used Apistan to control Varroas, and
after more than 10 years of their presence in the coutry we still have
nearly the same level of colony numbers. An effective complex of different
methods has been applied with the aim to use as little chemicals
as possible.
Those of you interested in details write dirrectly to the
Institute for Beekeeping at Dol,
