Our hive entrance dials are 3D printed in house with PETG UV reactive filament. Many flowers reflect or absorb UV light that humans can’t see but bees can and that helps guide them to flowers so the intent here is to use a UV reactive entrance dial to make it stand out to bees. This could be important for aiding in success of queens returning from mating flights, reducing drift and most importantly for helping scouts find swarm traps. Dials are based on a 1.5” hole size and are 4.33” in diameter with closed, open, vent and queen excluder settings.
