I put out traps for the first time this year. You hear many different recommendations for inside configuration . I have some five frames out and a couple deeps. All have a frame or two off old comb. Some I put extra frames of foundation in and some no extra frames. Since then I have heard to use a frame of comb and the rest empty frames with one horizontal wire for support. It seems some good trappers think filling the hive will all comb may deter bees moving in especially larger swarms as they are looking for open cavity space and not frame filled space. A nuc is 20L and a ten frame deep is 40L. They prefer the larger space but a deep is hard to handle in particular elevating it (I see capt puts two peat pot traps together) Robo has the plans for a compromise size trap of 30L on his website.
I baited some with lemon grass oil and some with swarm commander as a comparison. The only score I have had was in a deep baited with swarm commander. I did not have the extra frames in so I had to do a cut out. The wax was soft and next time I will have empty frames with at least one wire in place. I do not climb well and as you see I placed them near the ground. I am sure elevated is better but an emergency room bill and broke bones are not :)
