At some point in your life your kitchen could be invaded by ants. There are many different kinds of ant colonies that will do that, although the most prolific offender at the coast of Southern California is the Argentinian Ant. These Ants build their nest under anything that has a foundation above going 3 to 4 feet deep and anywhere from 7 to 10 feet out with in a diameter. Once a year treatment is rarely enough to control these guys. Having a maintenance service has proven to keep these invaders out of the kitchen.
