| Defining
Termites
Why is the Spring
considered termite season?
Over the course of the
year the termite colonies become large enough where they actually have
to start additional colonies. This is necessary because there is an
overabundance of insects in the nest. Like all social insects they have
what is called a swarm. Termites, bees, wasps, ants all act as location
scouts and are sent out to find a new venue. Swarming is a natural part
of insect behavior and is normally not a problem, unless the swarm
happens in your home.
How to determine
infestation?
There are several
different telltale signs of a termite infestation. One of course being
a swarm. It can be the end of February, or March, and all of a sudden
you’ll notice you have lots and lots of small black winged insects. The
most common areas are the front stoop or sliding back door. Also, any
area (such as) where you have wood in direct contact with soil. This is
a common occurrence at the garage door jam, the kick plate under the
front door, and the uprights that hold up basement stairs. In many
instances, the termites will not be discovered until they actually
swarm, which can be 3-5 years after they have infested the house. In
one case in particular, a homeowner noticed a large number of starlings
around her front stoop. This very common bird was eating the swarmers
as they were coming out of the kick plate of the house. Evidence of
swarming often happens near the front stoop. Often times, when the
house is being constructed, the front stoop is the last to be
constructed. The stoop is hollow wood filled in with rocks and wooden
debris from the construction site. On average, termites take
approximately 20 years to eat the debris under the stoop, before they
start on the house. Unfortunately, termites can make their way into the
frame of the house.
A good way for homeowners
to recognize there is a problem is by detecting shelter tubes or
tunnels. These are dirt lines about an 1/8 “ wide, which are usually be
recognizable in areas where wood meets soil. What a shelter tube does
is protects termites from predators such as birds and other insects. It
also acts like an air-conditioning system for them that keep a certain
moisture content and air pressure as it would be in the soil. …which is
their natural habitat. Areas where this is often found is in an
unfinished basement directly beneath the front or side stoops on or
between the sill plates. The sill plate is the first piece of lumber
that sits on top of the foundation. Also recognizable in some slab
construction the mud tubes will show up as little marks the size of
match heads on the dry wall. They are usually tan or terracotta in
color. These are usually telltale signs homeowners can look for.
Sometimes tubes can appear in the center of a basement away from the
foundation and can hang down as far a foot and a half down. This tube
is an exploratory tube that the termites uses to get back into the soil.
Why it is important to
recognize the problem?
Termites do not go away by
themselves. The house is the perfect environment for them to thrive
with plenty of soil around the house. The subterranean termite have all
the wood they need to eat because in this local, all the house are
comprised of wood frame construction. Also, the termites have enough
heat that radiates through the foundation that keeps them active
through the winter. Slab houses are built directly on top of the
termites’ natural habitat, which is soil. In slab construction,
contractors commonly bury construction site debris before the slab is
poured.
I had my house
inspected 6 months ago and didn’t have termites then, but I do now..Why?
Due to the way a home is
constructed you can go for years without termite activity being
detected. The termites were present, but not recognizable. This is why
there is a limited guarantee with termite inspections because in a lot
of instances they are difficult to detect.
Who should treat?
A termite infestation must
be treated by a licensed professional exterminator who will use a
termitacide. Termitacide are chemically engineered pesticides, which
are designed to bind with the soil particles. Termitacides are
effective because they are pumped down into termites’ natural
habitat…soil. A new generation of termiticides have emerged on the
market called “non-repellant” termiticides. These chemicals are not
repellents but rather they bind to the termite and is then brought back
to the colony by the insects as they pass back and forth through the
chemical.
Are chemicals safe?
Chemical companies spend
tens of millions of dollars on research and development to ensure that
the products can be safely used around humans and pets. It takes years
for these chemicals to be approved by the DEP.
Service agreements
Will they come back?
Sometimes termites will
come back because the chemical treatment wasn’t completely effective.
We have especially had problems with slab construction because there is
so much area beneath the structure that is hard to access. Also in slab
construction there are expansion joints used and they are comprised of
wood. Expansion joints are supposed be comprised of felt and tar but a
lot of times wooden 2 by 4s are installed instead. If concrete expands
and contracts without proper expansion joints to buffer the slab, it
will crack. The area where the slab and expansion joint meet is called
a key. This is where the termites come through to enter the house.
Also, when termite
treatments are done, customers are given written contracts explaining
conditions which will encourage termite infestation. These include all
wood to ground contact, shrubbery close to the foundation, wooden
fences, wooden debris and firewood piles in close proximity to the
foundation.
Lastly, an adverse
moisture condition will encourage all wood destroying insects,
including termites. Repair all plumbing leaks and direct all water off
of the roof well away from the foundation. Leaking gutters should be
resealed and kept properly aligned.
Where do they come from?
They come from the soil.
Termites don’t realize they are in a house. They are just doing their
natural function…eating wood. Termites natural function is to turn this
wood back into soil as part of the decaying process. Termites eat dead
tree stumps, fallen tree branches and tree roots so when we build on
top of their natural environment it is inevitable that we will create
this problem.
