Depends on why you're doing it. If the recipient colony is ok for bees, then shake 'em off to save depleting the donor colony. If they're not, then donate the rider bees as well. Vance's method involves more work, but comes with a Queenless guarantee.When I add a frame of brood to a hive do I need to shake the bees off first?
I tried this technique today. I wanted to move 2 frames of eggs to a queen less colony. So I shook the bees off the 2 frames and placed them back on the original hive over a queen excluder. I came back 4 hours later and transferred them to the queen less colony. I was surprised that there were not more bees on the frames. There were way less bees then when I shook them off. One frame was just honey and eggs and had very few bees. The other frame had eggs, larvae, and capped worker brood and had more bees but still very light on bees. Did I do something wrong?I have adopted Vance's method as well, it takes one to two hours depending on temps and population in the hive,
