Question for the pros... Is a 5 frame medium Nuc large enough to also use as a swarm trap?
I'm certainly far from a "pro", but will give my 2 cents anyway!
I have some 6 frame mediums that I've caught a couple swarms in, and know people that run nothing but 5 frame mediums as their swarm traps and do just fine with them. So...Yes they will work fine! Although I suspect they are probably not the optimal size. There's a lot of debate and discussion on what is optimal, but that being said, I think most would agree that it's probably larger than a 5 frame medium.
