Western Subterranean Termites
Swarmers are about 3/8 inches long, including wings. The body is dark brown to almost black. The soldier’s head is rectangular in shape, not narrowed toward the front. The length is fully 2 times the width. The mandibles lack teeth. They only eat the springwood and leave the lignin-containing summer wood which they cannot effectively digest. Hence, damaged wood appears to be layered. The colonies are usually located in the ground. Location is usually below the frost line, but above the water table and rock formations. Mud tubes are built to cross areas of adverse cracks less than 1/16 inches wide. If a constant source of moisture is available, colonies can exist above ground and without ground contact.
