Cindi, you are talking about a National Geographic Wild Chronicles documentary on Japanese Hornets Bees.
"A small but highly efficient killing machine lurks in the mountains of Japan —the Japanese giant hornet. The voracious predator pumps out a dose of venom with an enzyme so strong it can dissolve human tissue. Just a handful of these hornets can kill 30,000 European honeybees within hours. Watch an attack of giant hornets on a beehive."
However, the Japanese honeybee has adapted and survives these giant hronets!
I have the documentary on ZuniBee.com. You can watch it at:
