Look the same as the European honeybee, though unnoticeably smaller in size, Africanized honeybees are very aggressive, territorial, and may nest in awkward places. They defend their hive in large numbers, can stay aggressive for days after being disturbed. Africanized bees are extremely aggravated by loud noises, and vibrations. In addition, they are highly provoked by certain smells such as fresh cut grass and bananas.
