Termites and other wood destroying insects such as carpenter ants can do massive damage to a home and greatly impact its value.
Termites are ground insects that look for habitats that provide food, moisture and shelter close to the ground. Any place where wood meets ground qualifies, especially if the soil in that area stays moist. Correcting this situation may require re-grading to separate soil from any wood around your home. Since mulch and many other landscaping materials cause the soil to remain moist, you should make sure to minimize mulching around your foundation. You should also stack firewood as far away from a house as possible. Make sure that gutters and downspouts are in good condition and keep moisture from accumulating. You should also make sure to eliminate any moisture problems in and around your home, especially in basements and crawlspaces.
