I am hoping that Odfrank will chime in here as he seems to have the corner on this market, but looking for advice from all. I have 3 hives right now and am working to grow to around 30 over the next couple of years. To help grow I was kicking around the idea of putting out a couple swarm traps. I am thinking of using a hive box with a couple old frames. My question is how do you keep out the pests? I searched but did not find anything relating to this. However i did give up after looking through a dozen pages of hits.
