Ants are crawling around our house

A fun way to get rid of the little buggers is to place some sweet thing (Jelly, as Crash suggested, works well) and then just wait for the ants to swarm it. Once they do, you have two options. One, put a ring of lighter fluid around the jelly, and light that bitch up. They'll be trapped, and hilarity will ensue. They may not all die, though, which brings me to my next hilarious way to destroy ants. Instead of simply making a RING-O-FIRE, just douse the entire thing in lighter fluid. Throw a match in, and watch the ants go POP!

Jam it back in, in the dark.
