Subterranean Termites
Family Rhinotermitidae
Color: Creamy brown
Legs: Six
Shape: Long, narrow, oval
Size: 1/8
Antennae: Yes
Flight: Yes
Subterranean termites live in underground colonies or in moist secluded
areas aboveground that can contain up to 2 million members. They
build distinctive "mud tubes" to gain access to food sources
and to protect themselves from open air. Termite colonies are organized
into castes depending on tasks -- workers, soldiers and reproductives.
The characteristics of a subterranean termite are dependent on the
termite's role in the colony. Cream-colored Worker subterranean termites
are 1/8 to 3/8's of an inch in length. Soldier subterranean termites
are of a similar body length, but are distinguished by their powerful
mandibles. Solider termites have cream-colored bodies and brown heads.
Reproductive subterranean termites are approximately one inch long.
Habits
Subterranean termites live underground and build tunnels, referred
to as mud tubes, to reach food sources. Like other termite species,
they feed on products containing cellulose. Subterranean termites
swarm in the spring -- groups of reproductive termites go off to
start new colonies.
Habitat
Subterranean termites need contact with the soil to survive and
live underground. They can build tunnels through cracks in concrete.
Threats
Subterranean termites are by far the most destructive species. They
can collapse a building entirely, meaning possible financial ruin
for a homeowner. The hard, saw-toothed jaws of termites work like
shears and are able to bite off extremely small fragments of wood,
one piece at a time.
Subterranean Termites can be found in All 50 States
Prevention:
Avoid water accumulation near your home's foundation. Divert water
away with properly functioning downspouts, gutters and splash blocks.
Reduce humidity in crawl spaces with proper ventilation. Never
bury wood scraps or waste lumber in the yard. Most importantly,
eliminate wood contact with the soil. Maintain a one-inch gap between
the soil and wood portions of the building.
Formosan Termites
C. formosanus
Color: Yellowish brown
Legs: Six
Shape: Long, narrow, oval
Size: 1/2 inch in length
Antennae: Yes
Flight: Yes

Originally from China, Formosan termites are the most voracious,
aggressive and devious of over 2,000 termite species known to science.
Formosan termites are a subterranean species of termite. Swarmer
formosan termite are about 1/2 inch in overall length, including
their wings.
Habits
Formosans are organized into huge underground colonies, and build
intricate mud nests inside the walls of a structure.
Habitat
Formosan termites are the most aggressive subterranean termite species.
Formosans are organized into huge underground colonies, and build
intricate mud nests inside the walls of a structure.
Threats
Because of their aggressive nature, formosan termites are difficult
to control once they infest a structure. Prevention is key.
Formosan Termites can be found in AL, CA, FL, GA, HI, LA, MS, NC,
SC, TN, TX, VA
Prevention:
Avoid water accumulation near your home's foundation. Divert water
away with properly functioning downspouts, gutters and splash blocks.
Reduce humidity in crawl spaces with proper ventilation. Never bury
wood scraps or waste lumber in the yard. Most importantly, eliminate
wood contact with the soil. Maintain a one-inch gap between the soil
and wood portions of the building.
Drywood Termites
Family Kalotermitidae
Color: Light brown
Legs: Six
Shape: Long, narrow, oval
Size: 3/8" to 1 inch
Antennae: Yes
Flight: Yes
These social insects infest dry wood and do not require contact with
the soil.
Habits
They form colonies of up to 2,500 members. Unlike subterranean termite
species, drywood termite colonies do not have a worker caste. The
work is done by immature termites before they reach adulthood.
Habitat
Drywood termites infest dry wood, like that found in attic framings.
Threats
Drywood termites can infest structures and cause significant damage.
Drywood Termites can be found in CA, AZ, FL, AL, GA, LA, MS, SC,
TX, VA
Prevention:
Drywood termites can be avoided by making sure firewood and scrap
wood is stored at least 20 feet from the home. Because drywood termites
form new colonies by gaining access to wood through small holes,
seal all cracks and crevices in a structure.
Dampwood Termites
Family Hodotermitidae
Color: Brownish
Legs: Six
Shape: Long, narrow, oval
Size: 1/2" - 5/8"
Antennae: Yes
Flight: Yes
As the name suggests, dampwood termites infest wood with a high moisture
content. Dampwood termites are normally larger in size than other
termite species. Bodies of king and queen dampwood termites range
in size from 1/2 inch to 5/8 inch long and have two pairs of wings
that are equal in size and shape and extend beyond their abdomen.
Nymphs range up to 5/8 inch and worker dampwood termites are up to
3/4 inch.
Habits
Dampwood termite colonies, like drywood termites, have no worker
caste. The nymph dampwood termites take care of the kings and queens
of the colony and feed the soldier caste.
Habitat
Because of their need for excessive moisture, dampwood termites
are not often found in structures.
Threats
Dampwood termites do not usually infest structures because of the
low moisture content of wood in structures. However, care must be
taken to avoid attracting dampwood termites to a structure.
Dampwood Termites can be found in WA, OR, CA, NV, ID, MT, FL
Prevention:
To avoid dampwood termites, make sure downspouts and gutters are
diverted well away from the structure, and avoid prolonged contact
between a structure and large areas of moisture, such as ponds or
snow drifts. |
