Bees & Beekeeping : Bee Health


Varroa mites, Varroa destructor, are the most serious threat to honey bees. Varroa are relatively large external parasites that feed on the body fluids of adult and developing honey bees. Varroa cause physical damage, weaken bees and transmit a variety of pathogens, particularly viruses. In almost all cases, when varroa infestations are not effectively managed they will eventually result in the death of the entire honey bee colony. It is crucial that beekeepers manage the health of their honey bees by suppressing the population of varroa in all of their honey bee colonies throughout the beekeeping season.
