How do I make my home termite proof?
- Use termite-resistant building materials whenever possible. Redwood, cedar and juniper are all wood species that are less favorable to termites.
- Eliminate standing water and chronically moist soil near your home. Termites need moist soil to survive and are attracted to wet areas.
- Lay films of 6mm polyethylene in crawl spaces under foundations as a moisture barrier between the soil and subfloor framing.
- Create and maintain good cross-ventilation through foundation wall vents to keep those crawl spaces as dry as possible.
- Slope all exterior grades away from wood structures to maintain good drainage.
- Prune back plants close to your home to prevent moisture and mold buildup on wood walls.
- Water away from your home and adjust sprinklers to keep them from spraying directly onto wood walls and siding.
- Seal all wood exposed to moisture using a weather sealer, especially exterior window frames and the bottom of wall edges.
- Move all wood scraps and debris away from wood structures.
- Create sand barriers in crawl spaces and under fence posts, patios and steps to deter subterranean termites. These termites cannot tunnel through sand.
- Dig trenches 4 inches deep and 6 inches wide around wood structures. Fill the ditch with 16-grit sand (granules that are too large to be carried away and too small to be used to construct tunnels).
- Fill cracks and repair broken seals in foundations and patios with 16-grit sand. This is especially helpful after foundation settling.
