This is the second time I've read about "millions of bees" in a house.

10 million bees would seem to be the equivalent of 166 hives, given 60,000 bees in a hive. The most I've ever come across is 4 in one house, one hive in each 
wall.

10 million bees would generate a bit of noise. I'm thinking that around the 240,000 mark, someone would have noticed?

10 million bees would attract a ton-o-ants.

Media hype?
