IDENTIFICATION OF INSECT-DAMAGED WOOD

Termites
Termites are small, yellowish-white to brown insects that live in large
colonies in the soil.
Colonies are made up of many individuals, including a king, queen, workers, and
soldiers. The colony produces swarms in the spring. "Swarmers," which
are winged reproductives, suddenly appear in large numbers, but then quickly
disperse. Termites move in mud "shelter tubes" to get from the soil to
wood- or cellulose- containing materials like paper or cardboard.
Damage.
Interconnected, irregular cavities and tunnels are lined or partly filled with
claylike mud material. It appears "messy" with cemented mud in
hollowed-out wood. The tunnels often follow soft parts of annual rings,
producing a wafered appearance. Damage is most common near ground or foundation
or in wood close to or in contact with the ground. It is usually not evident on
unbroken surfaces. Hollow mud tubes called "shelter tubes" may extend
from the ground to nearby wood surfaces. Termites attack almost any kind of
wood.
