Has anyone used pressed pulp flower pots for swarm traps? This is the pot I am referring to. http://www.greenhousemegastore.com/product/western-pulp-round-pots/paper-pots
A member of my local bee club swears by these. He takes 2 6" or 7" pots and screws the openings together. That's under $2 for the pots per trap. Then using insulation foam, he seals all the holes but one. He then makes a hanger out of wire and washers. This seems small in cavity space. Tom Seeley says that swarm scouts look for a volume of 40 liters, which is a Langstroth 10 frame brood box.
Mann Lake sells a swarm trap made out of the same material for $23.95 each. I called Mann Lake and was told the dimensions are 13.5" x 15". That's not enough info for me to determine volume. The young lady on the phone put me on hold to measure, but she misunderstood me and measured the wrong end. I didn't want to put her out any more than I already had, so I thanked her and hung up.
So, has anyone made swarm traps from something similar? What was your results? Did they attract swarms?
