Don't Be A Victim Of
Termites!
-
If you own property and think
you might have termites call for a professional inspection.
-
Those flying ants may not be
ants at all, but swarming termites. And "wood worms" usually are not
worms, but worker termites.
-
If your looking to purchase
property have a professional termite inspection done. Why buy someone else's
problem?
More About Termites.
Usually once a year, a mature,
healthy colony will produce new reproductive termites called "swarmers".
The swarmers usually develop during the winter months. In the warmer months
when enviromental conditions such as temperature, moisture and light are
suitable, the workers construct "swarming castles" and usher the
swarmers out for their mating flight.
At times, large numbers of
swarms occur within a given geographical area. This helps assure that the
new reproductives have a greater opportunity to find members of different
colonies so that inbreeding is minimized. Swarming usually occurs for
approximately one - half hour. When conditions are less than suitable, an
individual colony may swarm several times over several weeks, releasing only a
portion of the swarmers each time.
Termite swarmers are not
strong fliers, but can be assisted by wind currents. Following a very
short flight period, the swarmers come to rest, break off their wings at a
special fracture point and attempt to locate a member of the opposite sex.
Males follow females in an attempt to mate.
Swarmers emerging indoors
usually die within a few hours and are seldom successful in starting new
colonies. An exception exists if sufficient moisture is found inside the
structure. Swarms usually occur in the morning following a warm
rain. Subterranean termite infestations may go unnoticed until a swarm
occurs inside the structure. The presence of swarmers is a sign that a
well - established colony is in the building.
A male (King) and female
(Queen) which find a suitable nest area - usually a ground contact beneath a
rock or wood - create a chamber and the queen begins laying eggs. During
the first season only a few dozen eggs are produced. The new workers begin
enlarging the chamber and collecting cellulose for food. At this point,
the abdomen (gaster) of the female begins to enlarge for increased egg
production. The queen's role then is strictly to produce eggs. A
mature queen produces 5,000 to 10,000 eggs per year.
Within four or five years the
colony is usually large enough for new swarmers to be produced and the cycle
repeats itself. Although the scientific community is not sure exactly how
long a queen lives, it is believed that a queen can live and reproduce up to 25
years. Swarmers inside a building do not indicate the termites have been
in that building that long. The colony might have discovered the building
during that season.
If the original queen is
eliminated or when larger colonies find new food sources that are somewhat
remote from the primary colony, healthy colonies can form secondary
reproductives. Secondary reproduction can also occur if large numbers of
workers are cut off from the colony ( as through a repellant type chemical barrier ) and there
is suitable moisture to support a new "satellite" colony. The
satellite colony eventually becomes independent of the original colony.
Under favorable conditions,
each mature colony produces swarmers yearly. For reticulitermes, better
known as, subterranean termites, large colonies may also produce secondary
queens which may emerge with swarmers and start new colonies. Swarming may
not occur every year if enviromental conditions are not suitable.
Post treatment swarms can also
occur. It is not uncommon for a colony to produce swarmers shortly after a
soil treatment with a liquid termiticide. If this occurs, it usually happens
within a few days and up to two months of the application. This response
may be due to the increase in moister from the water in the termiticide solution
or it may be in response to the treated zone as swarmers make a last - ditch
effort to escape. However, swarms occuring more than two months after
treatment usually indicates the treatment needs to be evaluated.
Termites are social insects,
which live in large colonies. There are three casts: reproductive,
workers, and soldiers. Termite antennae have bead like segments. The
winged reproductives (swarmers) have a pair of equally sized long wings that are
attached to the last two thoracic segments.
Termites feed on cellulose
materials with wood being the most common source. They are also known to
sometimes damage non - cellulose materials. Examples are pinholes in
plastic pool liners and plastic coatings on electrical cables.
Eastern subterranean termites
can forage as far as 250 feet from the colony in soil. Normally workers do
not expose themselves to light. If foragers must cross surfaces such as
concrete, they build tubes between the soil and the food source to protect
themselves from exposure to light and dry air. These tubes, (commonly
refered to as shelter or mud tubes) are composed of
soil particles cemented together with salivary secretions of the worker
termites. If tubes are broken, they quickly repair them if they're being
used. Broken tubes that are not repaired indicate the termites are not
actively using those tubes at that time.
Foraging termites consume
cellulose material and either take it back to the colony or pass it along to
other workers who transport it back. A long - standing myth is that
termites go back to the soil every 24 hours, but this has not been
substantiated. In fact, observations suggest that some workers may remain
in the wood above grade for several days at a time. The exchanging of food
among termites is called trophalaxis. This process permits the soldiers,
young workers and the king and queen to receive food.
The feeding rate of
subterranean termites has been measured. Native species in a colony
consisting of 250,000 workers can consume approximately 1 cubic foot of wood per
year. Under normal conditions especially in the New England States less
wood is consumed during a year as feeding slows during the winter months.
Larger colonies can cause damage at a greater rate. Subterranean termites
eat mostly the spring wood and leave the summerwood which they cannot
effectively digest. Hence damage wood appears to be layered.
Subterranean termites require
contact with a moisture source. The soil is the normal moisture
bank. Wood in which termites are working often contains up to 21 percent
moisture in the termite galleries. Normal, dry wood in structures usually
contains only 8 to 12 percent moisture. Termites bring wet mud into the
wood galleries to regulate the moisture in their enviroments.
When a repellant type termiticide is used to
create a treated zone in the soil, termites in the structure die either from the
lack of moisture or when contacting or crossing the treated zone to reach
the colony in the soil. Subterranean termites trapped above grade
following an application of a soil repellant termiticide can live up to two months
after the treatment. If there is excessive moisture in the structure, this time
may be
prolonged.
