Re: Deformed Wing Virus question

They have probably had it for thousands of years, but it used to be very rare and kept under control by the bees. Then, varroa mites jumped species from a different type of bee, and began infecting our bees. While using their proboscus to inject and feed on honeybees, varroa mites began spreading the DWV from bee to bee, to such an extent that hives with a lot of varroa mites can actually die from the virus.
The solution is to kill the varroa mites. The hive then will over time, purge itself of the virus.
So, how many bees can you see with DWV and it is still at a safe level? There is no one answer. Where i am, if a hive has just one bee that can be seen with DWV, it is a sign of a large varroa mite infestation, and the hive will gradually worsen and die, unless a treatment is done to kill the varroa mites.
In other areas, climates, and different bee strains and possibly different varroa mite strains and virus variants, hives with visible DWV infected bees can sometimes throw the infection off without beekeeper help.
So for you, find out what is the experience is of other beekeepers near and around you.
But most likely, if the hive has actually got to the stage where you are seeing a lot of "crawlers", it means the bees are not coping with both the mites and the viruses spread by the mites, and will die if the mites are not killed by the beekeper. If you look inside the hive and also notice dead brood, it may already be past the point of no return, and too late for the hive even if mites are removed.
