How important is it to have all the gaps sealed up in the top of the bait hive? When I built my bait hives i used that foam weather stripping around the edges and then screwed plywood down on top of that. Is that really necessary? To me it seems like a small gap or two is not going to stop or detour a swarm from moving in. In fact I would think they might even like it better. What is everyones opinion on this? I working on some bait hives right now and Im really wanting to just forget the weather stripping idea and get on with progress.
