Re: Any plans for larger swarm traps out of 1 sheet of plywood?
My suggestion is to make equipment do double duty. Use hive boxes for both traps and hives. If you want swarm traps bigger than a single nuc box, stack up two nuc boxes into one trap. Or, just use a regular hive body with whatever you have available for top/bottoms. A piece of plywood or even scrap OSB with some 'entrance' shims can make a trap bottom or top.
