Did you know that around here, every roach other than German roaches, come in from the outside and don’t infest the home? The old saying that if you see one roach in the house, there are a hundred in the wall doesn’t really apply. You’s have to have a major plumbing leak or really high levels of humidity in your home to create an environment where they could set up shop. Some things you can do to help make your home less inviting would be to minimize exterior lighting at night, be sure your exterior doors seal tightly and rake up leaves around the house.
