the second was a monster! itw as actually a little over three ft long and THICK with bees.... had to sweep several times to get them all and fortunately got the queen right away....i put the nuc box on the roof top and most of the bees went in but i had to make a several more sweeps and swept the bees onto a frame and placed it up near the nuc and they went in.....a bee vac would definately have been an asset.
When i dumped them into the hive they took up a good portion of frames....never did weigh them
As for the bee vac, once im done building it i will post pictures!
