Beekeepers often face various diseases in bees. In this case, it is necessary to use only proven and effective drugs. Polisan is a veterinary remedy that has been used for several years to treat bee colonies from ticks.
For what diseases in bees is the drug Polisan used?
Bees are susceptible to mite infestations. Such diseases are called acarapidosis and varroatosis. Ticks breed and breed in winter, when the bee colony is in a closed space. Parasites infect the respiratory tract of bees, and they die.
The first signs of the disease are difficult to notice. It can be asymptomatic for a long time. Later, beekeepers observe the birth of bee offspring with a small body weight. Such individuals do not live long. In summer, insects cease to perform their functions and fly out of the hive.
In this case, already at the end of summer, after pumping out the honey, they begin to treat the hive with the Polisan preparation. They do this during the period when the air temperature has not dropped below + 10 Сᵒ. In the evening, as soon as the bees fly into the hive, processing begins. The drug is opened immediately before the procedure. The drug will need 1 strip for 10 hives.
Tick-infected families are treated twice. The interval between fumigations is 1 week. For preventive purposes, young bee colonies are fumigated in spring and late autumn 1 time each. Honey after this procedure can be eaten.
