The Bee Escape Board also known as a Clearer Board is a board with bee escapes mounted into it. These escapes boards are placed between your honey supers and the hive. At night when the temperature drops, the bees will go through the escape to descend into the hive so they can cluster and stay warm. The escape is designed so that the bee can not reascend into the honey super once leaving. This process can take 24-48 hours.
