A while ago we had a small expeditionary force of ants invade our house. They weren’t withdrawing despite taking heavy casualties upon being discovered. They were nothing if not persistent. We tried conventional chemical weapons upon them, but didn’t seem fazed over time. Then I tried an old trick I learned from somewhere. I put coffee grounds at the point where they were invading the house (the back door in our case) and waited for more squads of ants. Apparently, these ants didn’t like fully caffeinated coffee which led me to think that my ants are either Mormon or on the Atkins diet which doesn’t allow caffeine. Either way, they haven’t come around any more. Once again, I am victorious over lower life forms. Go me.
