July 5th my hive swarmed. That was the day after I returned from vacation; not exactly the welcome I was hoping for. I just installed a bee package in April The swarm landed 50 feet up a Douglas Fir. We tried in vain to knock them down. They flew off yesterday, so there is no possibility of me getting my queen back (for another hive). I opened the hive 3 days after they swarmed and counted 23 uncapped queen cells located on the edges of the combs. I opened it up again today, July 14th and found all the queen cells empty! But they don't appear to have every been completed. I expected to see capped queen cells. Then a drone with 5 mites on his thorax landed on my thumb. I'm working with a top bar hive. Is there any chance of my hive surviving? Is it worth $$ to buy a queen for a hive that has varroas? Or shall I consider all lost?
