Shake, shake, shake!
I have always used the method of shaking the bees out over the frames where the queen cage has been positioned inside the hive body. I spray the bees in the package with some light sugar syurp before dumping them into the hive. This keeps the flying down to a minimum when I shake the bees out. I remove a few frames from the side to allow space to safely and quickly dump the remaining bees that are not shaken right over the queen. Then I carefully replace those frames and put the hive cover back on. I leave the package that the bees came in on the ground outside the hive entrance for those last few bees that seem to cling to the inside of the package cage. I generally install just before dark. When I come back the next day, the few remaining bees inside the package have found their way into the hive. This is what works for me. Of course, you must have feed for that new package so they can draw foundation. I come back in a few days to see if the queen has been released from her cage. If so, I remove the queen cage and make sure the frames are pushed together so the combs are built nicely. I resist the temptation to go into the hive for at least a week. By then I can tell if all is going well. Sometimes, I think it helps to keep your fingers crossed and utter a little prayer. Good luck to you!
