Dampwood termites commonly inhabit the Pacific Coast and Northern Rocky Mountain states, including Montana, Idaho, Nevada, Oregon, California, and Washington. Some species are also found in Florida and in Southwestern states.

Dampwood termites are one of the largest termites. Bodies of a king and queen can be as big as 5/8 of an inch long.

Dampwood termites do not require contact with the soil. They infest moist, decaying wood, sealing their galleries with fecal matter to maintain moisture.

Any wood that maintains high moisture content can host dampwood termites. Dead stumps or felled timber are their preferred habitat, but if you have plumbing leaks, poor ventilation, or inadequate drainage, your home or business is a potential host to dampwood termites.

Dampwood termites can escalate wood rot when they seal their galleries. They cut across the grain of the wood, weakening the structure until it fails.

Be sure to check any wood structure for places where moisture collects. Keeping wood from prolonged moisture is a sure way to keep out dampwood termites. If you suspect a dampwood termite problem, contact a pest control specialist right away.
