The Africanized strain of honeybees reached Maricopa County several years ago. All feral hives or swarms that are observed should be considered "Africanized". Maricopa County Environmental Services Department Vector Control Division investigates all feral bee complaints. We investigate to determine the responsible party, so they can remove the feral hive if needed. If you encounter a swarm or colony on your property, you should call your local pest control company to remove the bees. Vector Control Division of Maricopa County Environmental Services Division is not an Emergency Responder.
