You can buy a 20lb bag of granules for not much at the hardware store

Ah Amdro ... it moves the nest. Same with Orthene.

Perhaps this hasn't moved to the rest of the country but around here ants
maintain separate food streams into the nest and when one stream starts dying
off they switch food, perhaps even spawning off another nest if the queen was
killed. Contrary to what you heard in Science 1, they will take in orphan
workers from a dead colony. Those are the guys who avoided the poison so the
new best starts out smarter than the original.

I know I can hire a lawn service that will spray 30-40 gallons of poison on my
yard every now and then and hold them down a but but I also think about my
well.
BTW I can go show my neighbors with that service ants crawling around their
house too, a few days after the "inside" guy sprays..
