Excellent, thanks for the info Danno, I have got together a couple of test tubes, some cotton wool, a bottle of lemongrass oil, and some old OLD OLD dark comb.
I do have 1 question on using dark old comb - the frames I have are from a past SHB infestation (have been hosed out and frozen). Will any residual smell of the SHB/slime/possible fermentation repel the bees?? I have HEAPS of old dark frames that I took out of the infested hives. Are they good for swarm traps or should I just melt them down?
Last thing I need to do is work out the best container to put it all in.
Any suggestions anyone? I was thinking of making a plywood box that will fit 3-4 frames.
