Pesty Ants in a Green Environment

It has been raining cows and hogs here in the Bay Area for the last two weeks, almost non-stop! Therefore, I've had several visitors who have just made themselves at home. Of course ants will find their way into one's home mainly for two reasons: food and warmth. I keep my home immaculate, so I knew it could not have been for food. Obviously due to the weather conditions, it was definitely the latter. And it was just my luck that they were present in both my office and along the wall by my sliding door. Going green has taught me to no longer use Raid...now it's soap and water. This is the eco friendly tactic to use to kill these pests and keep them away without the toxic chemicals, which I would be forced to inhale as well. I have tried it a couple of times so far and it has worked very effectively. Go green!
