Battling Bug And Insect Infestation
By Jim Sulski
Summary: Insect infestations is a common household
problem. Bugs can eat or burrow through a home's timber - such as floor joists,
support beams and pillars - weakening the wood members. Jim gives the basics
about termites, carpenter ants, beetle, wasps and bees.
Remember those science-fiction films from the 1950s in which giant insects
would swoop down and destroy an entire house with a simple kick?

In reality, of course, bugs can't destroy a home that quickly. But over time,
left unchecked, insects can cause serious damage to the structural integrity
of a home.
What bugs can do is eat or burrow through a home's timber - such as floor joists,
support beams and pillars - weakening the wood members.
Technically, this problem is known as insect infestation.
Any home can be subject to insect infestation, which can cause tens of thousands
of dollars in damages.
For example, worst case scenarios can include collapsing floors or stud and
floor joists that need to be replaced because of bug damage. While you can't
avoid bugs, what follows are steps you can take to minimize their presence in
The "king" of damage-causing insects is the tiny subterranean termite.
Experts estimate that one in 16 Chicago area homes have a termite problem.
Although termites can appear anywhere, they are more likely to be found where
the ground is usually moist.
Termites cause damage as they eat wood, a staple of their diet. They are especially
attracted to damp wood.
Because daylight is lethal to termites, they travel underground, burrowing
until they come into contact with wood. They can enter homes through cracks
in basement foundations.
Termites eat wood only from the inside - so you can't see them at work.
To minimize the chance of termites, eliminate any damp wood or standing water
around a home by fixing gutters or leaks. And paint any exposed wood. Especially
pay attention to wood that comes in contact with the soil, such as porch posts.
Also cut shrubbery or branches that may come in contact with the house, another
path for termites.
To determine if you have termites, inspect the foundation walls inside of the
home, especially near any openings, for termites tunnels - half-circle dirt
tunnels that are about a quarter-inch deep.
Also, probe susceptible areas by jabbing an ice pick or awl into wood. If the
instrument penetrates the wood by more than a 16th of an inch, you may have
a termite problem.
Finally, check with your neighbors to see if they have had termite infestations.
If you do have termites, you will need a licensed professional exterminator
to eliminate the bugs with toxic chemicals.
The cost can start at about $1,000, depending on the size of the house. Pay
close attention to any guarantees offered.
If you discover wood damaged by termites, you should repair that damage by
"sistering": Shore up the damage wood by attaching an adjacent piece
of lumber to the original damaged piece.
Carpenter ants are also a threat to a home. As with termites, these large black
ants are attracted to wet wood. Unlike termites, however, they use wood for
nesting, not eating.
The presence of carpenter ants can be detected by finding the entrances to
their galleries on joists and posts. Also, look for fine sawdust near those
openings. You may also see the ants entering and leaving the galleries.
Then check the wood's integrity by probing with an awl or nail punch.
To minimize the presence of carpenter ants, again eliminate any sources of
damp wood. Also, caulk and weatherstrip any openings or cracks to a home, especially
around windows and doors. Repair any holes in screens and cut down branches
touching the house.
Carpenter ants can sometimes be eliminated by spraying commercial insecticides
into and around the galleries, said the experts. More severe cases can require
the services of a professional exterminator.
Powder-post beetles are another insect that can damage a home's wood, by chewing
into the wood to lay eggs. They prefer both dry and moist wood.
As with carpenter ants, powder-post beetles can be detected by searching for
small holes in posts and beams. Also, look for fine sawdust below the holes.
Similar to carpenter ants, the beetles can be eliminated with commercial insecticides.
To prevent further infestation, keep the wood dry and then seal wood with paint.
Also, seal openings and cracks, and repair screens.
WASPS AND BEES
These flying insects can nest in a home's walls by working their way through
an opening or crack on the exterior of a house. While they won't harm a home,
their openings are a way for moisture to get in. In addition, they sting.
These bugs can be eliminated with commercial insecticides, but follow the directions
carefully as not to disturb their nests. Professional exterminators can also
remove their nests. To minimize their presence, seal any small openings on a
