An established colony of Africanized bees (AHB’s) can be unpredictable. They will be defensive because their home is nearby. The reason they have been called “Killer Bees” is because many unfortunate incidents happened since they first entered the country. This is because they are much more defensive than their European relatives. They are more easily agitated; more of them will join the fight to defend their nest, and they will also pursue a predator longer and farther. They are simply more temperamental, but are not outwardly aggressive without provocation. These traits are genetically inherited and as such AHB’s are not good for beekeeping in urban areas. Remember, these traits have been developed and passed down over thousands of years from their ancestors that had to survive other predators and environmental factors in Africa.
