Those Japanese giant hornets are spawned by satan himself. Around 20 or 30 of them can wipe out a bee colony of 30,000 + and are huge in size comparison to bees.

The bees do kill hornet scouts by shaking their thorax and can handle literally 1 degree hotter in temperature than the hornets can withstand, but if the scout gets away its game over for the bees!

The documentary is called "Hornets From Hell" and was aired on the National Geographic Channel. Here is a 7 min clip. Please vote and follow me if you like this video. Thanks
