About Termites
There are more than 2,000 species of termites which cause more than
$750 million worth of damage each year. The most damaging include
about 20 species called "subterranean" termites because of their
nesting and foraging habits. A subterranean termite colony contains
60,000 to 1.5 million termites and includes reproductives, soldiers
and workers, each with distinct functions and behaviors.
Termites feed on cellulose, a complex chemical in plant cell walls,
and are very important in the natural decomposition of fallen trees,
leaves and other plant products. They may also destroy paper products
such as books, cardboard boxes, and furniture. Even buildings with
steel framing and masonry walls are target because of wooden door
and window frames, wooden support beams, cabinets, or shelving.
They build their nests in the soil or in the sides of trees or
poles, and rely mainly on the soil for their source of moisture.
As their colony numbers grow, they search farther from their nests.
They make underground tunnels or above-ground "shelter tubes" of
mud, feces, and debris.
They can enter a building without direct wood contact with the
soil through such tubes. They can enter buildings through cracks,
expansion joints, foam insulation below ground, hollow bricks or
concrete blocks, or through spaces around plumbing. They need only
an opening as small as 1/32 of an inch to gain access to a building
whether constructed with a slab, basement, or crawlspace foundation.
Worker
termites are small (0.1 - 0.25 inches long), creamy-white insects
which are seldom seen by the property owner as are the soldiers.
All termites have antennae that look like a "string of beads" and
a "thick waist" where their abdomen is joined to their middle body
region.
Soldiers
are larger than the workers (0.2 - 0.4 inches long), about 1/20th
as numerous as workers, and have a large dark dead, with long, strong,
sharp-pointed jaws which they use to attack intruders.
Reproductives
consist of the queen, king, and winged swarmers. As the termite
colony reaches more than 10,000, winged reproductive "swarmers"
are produced and leave the colony in a "swarm". This swarm is made
up of 50% male and 50% female reproductives.
Pairs mate and begin a nest in a suitable piece of wood. The pairs
are mated for life. Each new queen can produce 1,000 eggs per day
by her fourth year of life. Other members of the colony can change
into reproductives if necessary to replace a lost member of the
pair.
