Drywood Termite

Subterranean Termite

Drywood Termite

Description:

The Drywood Termite can be up to ½ inch in length.  Reproductive termites take the place of workers when they are nymphs.  The reproductive class has two pairs of equal size wings and is reddish brown in color.  Soldiers have long dark heads with two black mandibles.

Behavior:

Because Drywood Termites are social insects, they live in colonies. The colonies are made up of kings, queens and soldiers. There is no worker caste in a Drywood Termite colony. The work is done by the nymphs before they become adults. King and queen termites perform the reproductive functions of the colony.  Soldiers guard the colony against predators such as ants or other insects.  While soldiers nymphs remain inside the wood at all times, the reproductive caste will swarm in certain times of the year to make new colonies.  Drywood Termites nest above ground in sound wood.  An infestation is identified by piles of light and dark colored fecal pellets.

Control:

Drywood Termite Damage

The chances of a Drywood Termite infestation can be reduced by storing fire wood and lumber away from a structure.  Fine screening should be installed on all windows and ventilation openings for attics and crawl spaces.  Any exposed wood should be sealed with varnish or paint to prevent termite access.  Nail holes and cracks should also be sealed.  Large infestations of Drywood Termites are exterminated by tenting a building and pumping a fumigant inside.  Alternative methods include thermal remediation, liquid nitrogen, and spot treating with a borate.

Fun Fact:

Drywood Termites are one of the few species of termite that cut across the grain when infesting wood.
