The ants go everywhere, invading homes and nesting in walls and crawlspaces, even swarming inside appliances. The ants are not attracted to ordinary ant baits, are not controlled by over-the-counter pesticides and are harder to fully exterminate than many other species because their colonies have multiple queens. The chemicals that kill red ants aren't effective on crazy ants, so if you find an infestation in your home, it is best to call a professional.
