The Bee Escape works like a one way door to let bees out but not back in. You insert the bee escape in the hole in an inner cover and place it under the supers you want to take off. We recommend placing an empty shallow super under the supers you are taking off to give the bees more room. In a few days, depending on weather conditions, the supers will be clear of bees and can be removed. Should there be any way for robber bees to enter supers you are trying to take off they will rob the honey out and you will lose your honey so bee-ware!
