For those of you looking to build some swarm traps read this. This year i searched high and low for good swarm trap plans to maximize the use of materials and minimize costs. After a lot of research, I finally decided to just draw up my own. I read Tom Seeleys Honey Bee Democracy and took some notes and ideas. I wanted a trap that was as close to 40L as possible, that would hold frames to make transfer easy, be taller than wide to allow for a fewer number of frames to be used by traps while also making it easier to hang. I also wanted something that i was able use nuc tops on, that way i could dual purpose some of the equipment. Finally i wanted something that if all went to crap and i was short equipment i could cut down to make 5 frame nucs. After a lot of rough attempts, I finally came up with these plans. After a trail run i enlisted the help of my friend troyheckman on beesource to draw them on sketch up so i could share them. They are super simple, cheap and consist of relatively straight cuts. You can make 12 traps from three sheets of plywood or 7.5 from two. I go to home depot and have them precut sheet one to 16"-40"-40", sheet two is cut to 40"-36"-remainder. I then finish them on a table saw. Inside dimensions measure out to right 37L. I then drill a 1.75" hole 2" from the bottom in the center of either the side or face. I tried to make them a little larger but was unable to achieve such little waste. I assemble with glue and staples. My cost using home depot lumber is just under $6.50 including lids. To get 12 traps you will need 2 sheets of sheet #2 and one of #1. Everything is color coded off the final diagrams.
