My first time trapping all I had were mini top bar hives with a piece of string drizzled with bees wax for comb guides. I rubbed the inside of the trap with the same wax and put a few drops of LGO at the entrance. I caught two swarms with 5 traps. One of the biggest factors is location. There has to be bees around, I put out a bit of honey on plastic lids from dairy containers and spread them around the area where I think it looks good. I wait a hour or so then go back and check to see if bees have found the honey. There are many threads on B.S. about location do a search and you will find lots of info.Is it absolutely necessary to have a swarm trap with drawn comb present? I'm thinking of building one, but don't have any drawn comb available at the moment.
