Termites
In most parts of the United States, subterranean
termites living in large colonies are the
most common type of termites that infest
buildings. These insects live in the soil,
where they construct elaborate networks of
nests and tunnels which can stretch for hundreds
of feet to reach the food and water necessary
to keep them alive. When these insects attack
wood that is part of the foundation of the
structure, they can follow the framework
of the building to the upper levels, eating
their way through the wood and causing severe
damage. Homeowners may not know that their
property is at risk until much damage has
been done.
If you want to protect your home from termites,
consider the following:
- Important preventive measures include keeping
the ground around the foundation of the house
clean and dry. Avoid the use of wood mulch
around the foundation, and never store firewood,
lumber or paper next to the house or in a
crawl space. Make sure there are no permanent
patches of wet soil near the house.
- The first signs of termite infestation are
usually a “swarming” of termites in the spring,
as some of the insects leave their nest to
form a new colony. Finding shed termite wings
on window sills or other surfaces is evidence
that a swarm has occurred. Another sign is
the presence of mud tubes on boards and beams.
If you discover either of these signs, you
will need to take immediate measures to control
the termites.
- Most homeowners do not have the experience
or equipment to eliminate termites on their
own. It is usually necessary to hire a licensed,
certified pest management firm. These businesses
will apply a toxic chemical to the soil so
that a continuous barrier is formed next
to and under the foundation of the building.
- Other treatments for termites exist, but
they are often not nearly as effective as
chemical barriers. Termites may simply tunnel
around areas that have been “spot” treated
with toxic products, while biological control
agents such as nematodes or funguses have
not proven effective in the long term. Termite
baits are slow acting and require proper
monitoring and maintenance.
When hiring a termite management service,
it is important to select a reputable company.
Prices for inspection and treatments can
vary considerably. Be sure to read all warranties
carefully. |
