When a honey bee hive becomes overpopulated, they swarm in search of a new home. A swarm is about 1/2 of the population of a hive, or about 20,000 honey bees. They may temporarily land on your property or take up residence in your home. This can be an intimidating sight, however, please do not call an exterminator. If you have a swarm on your property or they have relocated in your home, find a beekeeper close to you that can remove them safely.
