Reducing moisture around the home will help reduce the presence of pests in the home.  Since most pests thrive in areas where moisture is present, the homeowner would be well served to inspect the property and make necessary corrections. Changes may include — but are not limited to — cleaning out gutters, grading soil properly so that water moves away from the foundation, ventilating crawl spaces, and sealing cracks in the foundation.  Not only will such measures aid in pest prevention, but they will improve the health of the home in general.
