Last season I took out 4 bee nests, two from trees and 2 from house walls. The attached video is a trapout I did from a oak tree. The nest was large and I filled 15 frames with bees and got the queen out. It took 6 to 7 weeks but well worth it.
Trapout in action.
Taken from a ladder. Sorry for the wind noise.
