Drywood
Termite
Characteristics –
Size: Soldiers measure 3/8-inch in length; male and female
reproductives grow to 1/2-inch long. During the winged stage there are four
equal size wings that extend longer than the body by 1/8- to 1/4-inch.
Color: Usually pale brown.
Drywood termites have soft bodies and are cylindrical in shape. They have six
legs, compound eyes and chewing mandibles.
Behavior –
Drywood termites are social insects that live in colonies. The colonies are
composed of kings, queens and soldiers. There is no worker caste as in
subterranean colonies. The work is performed by immature termites before they
become adults. King and queen termites perform the reproductive functions of the
colony. They are light to dark brown and 1/3- to 1 inch in length. Soldiers
guard the colony against invaders such as ants. They are white and wingless with
large brownish heads and jaws. The nymphs (immatures), which are the most
numerous caste, are white and wingless. The soldiers and immatures remain inside
the wood at all times.
Habitat – Drywood termites infest only dry wood and are most
often found in attic wood structure as they do not require contact with the
soil. They need very little moisture because they are able to live off of the
water produced from the digestion of the cellulose. Drywood termites mate and
fly to new dry wood areas, enter a small hole in the wood, and start to form a
colony. Colonies will contain up to 2500 members.
Tips for Control – There are some things a property owner
can do to help prevent drywood termite infestation.
 | Store firewood and lumber away from the house.
 | Use 20-mesh screen on all windows and doors, and especially at ventilation
openings for attics and crawl spaces.
 | Exposed wood that is sealed with a uniform coating of paint, varnish or
other sealant will help prevent easy access by drywood termites. Be sure to
seal nail holes and cracks. |
