Change 1 light bulb = finding 10,000 bees?

Two Miami roommates needed help to get rid of some unwanted visitors in their apartment. They discovered more than 10,000 bees in their kitchen ceiling.

Javier Tovar didn't know the hive was there until he tried to change a bulb in a ceiling light and the bees attacked him. The roommates quickly called in an exterminator.
"We thought maybe there may be a fist-size hive, but he just pulled out a basketball-sized hive. It's amazing," Tovar said.

The exterminator discovered that the hive belongs to a colony of Africanized bees, which are even more aggressive than normal bees. Article here.
