you wake up, you are immortal(you do not age, you cannot get hurt, you do not need to sustain yourself). God himself has come down and told you "YOU HAVE to kill every wasp", and then vanishes forever. You look outside and there are no more humans. Other animals are still there just no more humans, just a world left behind. You have to kill every wasp.

When all the wasps are dead, god himself will come down again and reset the planet to how it was before, he'll bring back the humans and reset the enviroment (except for the wasps they'll stay dead)

how long would it take for you to kill every single wasp
