I know all Lang hives have landing boards. Some top bar hives do, some don't. Not sure on a Warre hive. My question is: Has there been any study to determine if a landing board is helpful to the bees or not? I wonder if it doesn't give the small hive beetles a place to land and climb into the hive. Also wondering if the height of the hive entrance has anything to do with the pests that get in there, such as the small hive beetle. I would figure the amount of vegetation that surrounds a hive entrance also contributes to the pest population.
