A week after a swarm of highly aggressive bees terrorized one street in a Concord neighborhood, bee experts warn that no one should jump to any conclusions about what type of bees these were, or what caused them to swarm, attack, and injure two people in addition to killed two dachshunds. The bees in question are still off in a lab being DNA-tested, and as Deborah Bass, a spokesperson for the Contra Costa County Vector Control District tells the East Bay Times, "We still do not have confirmation that these were Africanized bees. Until these are confirmed, we have no knowledge of Africanized bees anywhere in Contra Costa County."

Now, this contradicts a report from last September by some UC San Diego bee researchers about Africanized bees having moved into a part of Briones Regional Park — which is in Contra Costa County. Bu apparently those researches back away from their claim after the Chronicle trusted them, and they now say they never classified the bees as Africanized officially and never found a hive.

Reportedly Africanized bees were found in Crockett back in 2008, but no hive was ever established there.

The Concord incident, as we now learn, began when amateur beekeeper Arthur Janke opened the lid to a case containing one of his hives. He says the hive just "exploded," and separate swarms of 20 to 30 bees each attacked Janke, a mail carrier, and a neighbor across the street, as well as the two dogs.

Bee experts say that European honeybees in a stressed out hive could have easily done the same thing. But even if these were Africanized bees that had taken over an existing hive, UC Davis Cooperative Extension apiculturist Elina Nino says the incident sounds "unique" and this would not have been typical behavior.

So, calm down, everybody. You're not in danger of dying a horror-movie death at the hands of a swarm anytime soon.
