I agree Al.  It’s been said that he who sleeps on the ground cannot fall out of bed and die, so we can’t wait for them to go to sleep and push them out of their beds.  While it’s true that we can’t get them to leave, there is one sure way to get rid of them.  First, mix some chili powder with sugar and put a few piles of it outside their hole.  After they eat it, they will search for some water, most likely at the nearest water tank.  When they climb up the side of the tank to get water, simply be there waiting for them and push them in.  When they finally get out of the water, they will immediately look for a fire to dry themselves.  Since they might recognize you from the water tank and become a little suspicious, you’ll need to be as inconspicuous as you can and follow them to the fire.  When they least expect it, throw a bomb into the fire.  Then, follow the survivors to the ICU and remove their oxygen masks, which will kill them in a matter of seconds.  The thing is, I'm not afraid of them taking over the world because it would take about a million of them just to aim a gun at me, let alone fire it. And while they're all focused on getting the gun set just to aim it at me, I’d slip off to the side, and then I’d suddenly run up and kick the gun out of their hands, rendering them completely helpless.  The thing to remember during the confrontation is to remain calm and never call them “ants”, because they hate that.
