Dampwood Termites
Dampwood termites form one of
the three major groups of termites that feed on wood. Unlike other
termite groups, dampwood termites specifically feed on damp,
decaying timber, as what their name suggests.
They are usually found in the states along the
Pacific Coast, including Montana, Northern Nevada, Idaho, Northern
California, Oregon and Washington. However, a less damaging species
of dampwood termites can also be found in Southwest USA and certain
areas in Southern Florida.
Distinguishing Characteristics
Like all termite types, dampwood
termites live under a caste system comprised of
reproductives, soldiers and workers. A typical termite would
undergo the following stages: egg, nymph, adult. There is no pupal
stage in the termite life cycle.
The eggs and nymphs of termites do not look
apart from each other, regardless of species. It is the adult that
one can notice marked differences. One of the most obvious
distinctions that dampwood termites have is that they are generally
much larger – more than a half inch.
Swarmers, or alates (the female or male
reproductives of termites) are about an inch in length, including
their wings. Soldier dampwood are also larger than a typical worker
termite, with huge reddish-brown heads and large mandibles.
Feeding Habits
Unlike subterranean termites, dampwood
termites do not form shelter tubes when they travel across
the ground surface towards a certain food source. Because they do
not depend on constant contact with soil to maintain their moisture
level, dampwood termites have no use for shelter tubes.
It is difficult to identify the damage caused by
dampwood termites during the early onset of the nesting period.
Termites are, by nature, secretive insects, and dampwood termites
usually hide behind the wood they are eating so one cannot see.
Only when the timber starts to show surface damage would a person
be made aware that the wood has been infested.
Dampwood termites typically eat wood across the
grain. They would consume both spring and summer wood. As they
consume first the interior of the wood, they would create a series
of chambers or galleries which are interconnected to each other by
tunnels. The walls of these tunnels are often smooth as they were
sandpapered.
How to
Avoid Them
Because dampwood termites would
only consume wood that are “damp,” it is best if you stay alert if
your house is made of wood with high moisture content. Also, wood
that is contact with the ground or found near a leaking faucet may
be highly susceptible to dampwood termite infestation.
As they eat, dampwood termites excrete faecal
pellets about 1/32 inch long. If you find any of these
powdery-looking pellets anywhere near wood, such as furniture for
instance, there’s a likely chance that you have an infestation in
your home.
