The best method to protect against termite infestation is to eradicate the colony and prevent them from setting up shop on your property. The National Pest Management Association recommends preventing termites by: Removing the conducive conditions termites need to survive. Termites love moisture; avoid moisture accumulation around the foundation of your home. Divert water away with properly functioning downspouts, gutters and splash blocks. Reduce humidity in crawl spaces with proper ventilation. Prevent shrubs, vines and other vegetation from growing over and covering vents. Be sure to remove old form boards, grade stakes, etc., that was used during building construction. Remove old tree stumps and roots around and beneath the building. Most importantly, eliminate any wood on the building from contact with the soil. An 18-inch gap between the soil and wood portions of the building is ideal. It doesn’t hurt to routinely inspect the foundation of your home for signs of termite damage. Additionally, the Insulating Concrete Form Association recommends soil treatment and re-treatment over the life of the home. Just because the home is built of concrete does not mean the termite will give up trying to get to its food source: wood! When using ICFs below-grade, the International Residential Code calls for chemical treatment of the soil and an approved method for protecting the foam. This can include chemical treatments fused into the ICF form, as well as physical barriers.
