Mosquitoes. I hate mosquitoes more. Wasps might be mean, but they still generally only attack if they have a reason. And at the end of the day, they are still an important pollinator.

Mosquitoes are out for blood. They will seek you out for the sole purpose of biting you. They carry diseases. Their bites itch for days and they come in swarms. A sting from a wasp will only hurt for like a day, and when was the last time you got attacked by more than one or two?

I hate wasps, but they are not the most evil, just second most evil.
