1. Would anybody notice?

2. It might be a buzz.

3. I wouldn't go swimming on a full moon.

lol That was good!

Oh yes, my friend, you would notice... Ants make up about 20% of the terrestrial biomass (10 quadrillion ants). If they all became zombified, and went out to kill every living thing, you wouldn't have the luxury of worrying about human zombies. There wouldn't be a bunker safe from ants.

You'd have to leave dry land and try to live in an ocean bioshere. Where you'd get crushed by the 100 foot (30 meters) long, 170 ton werewolf blue whale.

^^ Somebody needs to make that movie. :)
