Here is a homemade swarm box (aka "bait hive") that I made from an old deep box and some plywood I had sitting in the garage.  

I got creative in the painting process, where I put on some green paint, and then after drying, added some darker green-black paint, applying it with a plastic bag and blotting it to simulate a camouflage effect.  

Some old wood and a little paint, will hopefully attract bees to this new temporary home, and bring new bees to Queen City Bee this Spring.
