Varroa mites (Varroa jacobsoni and V. destructor) are the most serious pest of honey bees worldwide. The mites are tiny reddish brown external parasites of honey bees.
On their own, individual mites are easily identifiable to the naked eye. Left untreated varroa mite will kill any bee hive it infects. All feral and untreated bee colonies will eventually die.
Drone bees are able to move varroa mites from hive to hive and even between apiaries. Mites are agile, move into hives quickly and transfer through contact between bees. There are strict quarantine requirements in place to protect the Australian honey bee industry.
Varroa infects honey bees in every major beekeeping area of the world, except Australia.
It is estimated that varroa mite could result in losses of $70 million a year should it become established in Australia.
