James, here is some free advice so feel free to take it or leave it. Concerning your question about being too early, it is not too early now. Remember, in order for your new queen to be successful, and maybe even whether they make one at all, there needs to be drones for her to mate with. That time is now for me (about 5 hours South of you). I never use that spray foam on a trap out. Silicone caulk is about the same price and they do not chew through it. Much less headache involved. If there is any possible way for them to get back in original hive, they will do it. If they do, you trap is not going to work. I would say that your exit of the cone is too big, but from the vids, it does not look like they are going back in. If you have to fine of a mesh, or too many layers of mesh, they can view it as a solid structure and walk out to find the end of it. I like my cone to me one single layer of #8 so they can see through it very easily but cannot get through. I would try to either turn your trap with the entrance hole pointed at the base of the cone or drill another entrance. Once you place a frame of brood in there, you want them to catch a whiff of it very easily. Kind of like walking around at the county fair and getting a snort of some good BBQ from a nearby booth. You just gravitate towards it. What I like to look for is a quite a bit of confusion on day one or two, but then you want to see some order to them orienting to the trap. I second what Hardwood says. I learned most of my trapout stuff from iddee. The rest I learned from vmmartin doing it wrong. Hope this helps. Looks like a pretty good size hive in there too.
