Is an Intrance reducer necessary with a flow hive??
I always use entrance reducers, even on my Flow hive. You can make a simple one from stacked paint stir sticks, craft sticks or wood shims. I like to reduce the entrance to about 6" wide, based on Thomas Seeley’s research on bees’ preference for an entrance of 15 square centimeters. The flow entrance is about 1cm high. Six inches is 15cm, so that is why I do it that way.
Entrance reducers help reduce robbing, make it harder for pests to enter the hive and probably improve the efficiency of fanning for ventilation.
Thank you for that info Dawn. I will do the same. By the way thank you for all ways responding. I’m starting to look to you as my bee mentor.
