Insects are an unavoidable fact of life, particularly in the summer. Unpleasant though they may be, household pests are usually benign. However, it would be a mistake to forget that some critters pose a genuine threat—termites most of all. Do due diligence to prevent an infestation. Indoors, keep the basement and attic dry and well-ventilated. Outdoors, maintain a one-inch gap between soil and wood portions of the home, and tightly seal foundation cracks.
