So you think wasps are bad? You ain't seen shit yet.
If you're one of those people who will change your route to work because there might be a wasp's nest near the path you normally use to get there, then be glad you don't live in Japan. Because in Japan, they've got giant Japanese hornets instead of normal wasps.
...Ok, they probably have normal wasps there too, but next to these fuckers a regular wasp doesn't even register as so much as a nuisance. Your average giant hornet is 5 times the size, and 20 times the weight, of a normal European wasp. And they've got a sting to match: A European wasp is content with just having a painful acid for a sting; giant hornets have flesh-melting poison as well as a neurotoxin that, when combined, can kill an adult human with a single sting. And, a painful acid too, just for added fuck-you-in-the-face factor.
To put all this shit into perspective: European honey bees are not threatened by European wasps, because they're the same size as each other and the bees have a huge number advantage over attacking wasp swarms. They easily fend off wasps... but when the same number of Japanese hornets find a honey bee nest, the ensuing one-sided bloodbath really does have to be seen to be believed. Remember: The honeybees in this video are the roughly same size, and temperment, as the wasps you think are so bad.
So the next time you get a wasp buzzing around you, by all means shoo it away and / or get the can of Raid out as you always would, but just remember: The natural world can be a scary goddamned place, and you're lucky to get off so lightly as to only see the minor annoyances, instead of the airborne engines of suffering they've got elsewhere in the world.
Have a nice fucking day.
And if you DO live in Japan... well, sucks to be you. :P
