Our mating grounds are in an area where Africanized bees have been for about 20 years. We feel the African bee incursion did severely affect our stock's temperament for the first 5-10 years, beginning in 1994. In the ensuring years, many of those feral African colonies have been watered down by our bees, existing feral bees and other US beekeeper's stock. Inter-breeding with feral Africanized bees does undoubtedly continue but we take measures to minimize their influence.
