I thought to ask this awhile back when I was hauling in my traps for the season, but forgot to and just remembered now. I had a trap placed from april through fall and I checked it each week for activity in the spring. I never saw bees traveling in or out and assumed it was left unused by the bees. Upon retrieving the trap I popped the lid to see that one of the frames was drawn with new, light colored wax about 20% starting near the top of the frame and arcing downwards. Obviously this was new wax as the frames I placed inside were all old, dark wax frames. So what happened here? Did a swarm move in for a very short time and then leave again? It would have had to be for less than a week that any bees were in it since I checked once per week. This was my first year placing traps and was unsuccessful across the board but seeing this wax leads me to believe that maybe I should try this location again. Thoughts?
