Carpenter ants, outside, are a part of Ma Natures recycling machine and do not need any control measures taken. If the Carpenter ants are in your house that is an indication of a serious problem, wet wood, that needs to be fixed. Poisoning the ants is not the solution since the real problem will still exist and simply will draw more of those ants in the future. Fix the real problem and those Capenter ants will go away without the use of poisons.

Unfortunately kimmsr, you are only 1/2 right. Yes they look for water but shelter is another staple of life they must have. Water or not they may choose to live in the voids of your wall or in your attic just because it's there. I see your point and the more conducive the more attractive the site but only in the south east is moisture a necessity for them choosing a site to live in.

Baits are a very responsible way to go but c-ants are so finicky they seldom work. Non repellant liquids work best.

Integrated Pest Management, IPM, is a system of understanding the potential pest and starting with the least toxic means of control, if that is necessary, to control that pest. IPM is not starting with the most toxic poison you can find and pouring that around in the hope that it will solve your problem.
