Common Signs of Carpenter Ant Infestations in and around structures
Frass, which is made up of wood
shavings, bits of soil, dead ants and parts of insects. This material is often piled
up outside of nest openings and found in spider webs and window sills.
Small windows or slit-like openings
that carpenter ants cut into infested wood. These windows are actually
"garbage chutes" which are used to dispose of frass or unwanted materials.
Swarmers are the winged
reproductives that take flight in the spring. Look for them trapped in spider webs,
on window ledges or in light fixtures.
Worker carpenter ants are active
mostly at night, so you may not see any activity during normal working hours. Even
if you do, it does not mean that the nest is nearby. Worker ants can travel up to
the length of a football field booking food.
Clicking or rustling sounds can
sometimes be heard coming from carpenter ant nests. If you identify a potential nest
site, try tapping against it with a screwdriver. You may hear a response -- the
clicking of alarmed ants. The use of a stethoscope makes listening easy.
Wood damaged by carpenter ants
contains galleries that are very clean and smooth.
The first sign of a carpenter ant infestation is usually the sighting of
numerous workers throughout the home. However, the presence of workers alone is not
conclusive evidence that a colony is established within a structure. Carpenter ant
workers tend to roam far and wide looking for food, and some transient workers are sure to
enter any home located in a wooded area. Signs of an active infestation include the
presence of fibrous sawdust beneath slit-like openings in wood members and faint, rustling
noises in walls and woodwork. A positive indication that an active, mature
infestation is present is the emergence of large winged ants from walls, ceilings, or
Carpenter ant galleries in wood have smooth surfaces and can be differentiated from
subterranean termite damage by the absence of "mud" in the galleries. Ants
normally excavate wood that has been softened by decay or other insects, however, they
will tunnel into sound wood when conditions are favorable. Nests and galleries may
be located a considerable distance from the point or points of entry. In addition to
structural lumber, sites such as hollow-core doors, window headers, wall voids, and foam
panels are particularly attractive to carpenter ants.
Carpenter ants often enter homes through openings such as foundation or attic vents,
cracks, plumbing holes, entrances for telephone and electric wires, etc. One thing
to look for during an inspection are tree branches that may be just above or in contact
with the roof. Firewood piles are prime nesting sites and should be treated with an
appropriately labeled pesticide such as Advance Carpenter
Ant Bait, Suspend SC or Cynoff. Advance Carpenter Ant Bait is a bait that is scattered
around piles of wood, Suspend SC and
Cynoff are excellent pesticides used
for immediate kill and long term control of carpenter ants and many other insect pests. If
damage to fire wood is extensive, simply dispose of the wood.
