I've had a long running war against ants. They're an annoyance that seeks to steal my food, damages the house foundation, and occasionally bites me during the night. The usual way to deal with them involves dumping neurotoxins disguised as food on their nests. They eat it, share it, and all collectively die. Especially the queen ant, who is more literally "mommy ant." Without her, the last ant of the colony dies of old age, squishing, or being eaten in short order.
A big annoyance, however, is that I can only really find their nests after they've built up a bit. A small ant nest goes completely unnoticed. Until they build up to extreme irritation levels.
Biologists have successfuly reverse engineered the chemical signals that ants use to navigate, so I'm tempted to get their "ant pencil," which traces lines not of graphite, but of "food" signal, and leading them to a big pile of the neurotoxin. They won't be able to resist. Muahahahaha!!!
