OVERVIEW:
Carpenter ants get their name because they excavate wood in
order to build their nests. Their excavation results in smooth
tunnels inside the wood. Carpenter ants range in size from
¼ of an inch for a worker ant to up to ³⁄₄ of an inch for a queen.
PREVENTION:
• Eliminate sources of moisture or standing water. Be especially
vigilant in protecting crawl spaces, basements and attics.
• Trim tree branches away from your home.
• Fill any gaps or cracks on the outside of your home with
silicone caulk.
• Make sure that firewood and building materials are not stored
next to your home.
• Inspect wood on your property for signs of an infestation,
such as the appearance of small openings on the surface
of wood.
• If you suspect you have a carpenter ant infestation, contact a
licensed pest professional.
HABITS:
Carpenter ants typically attack wood that is or has been wet.
They usually come into buildings through cracks around doors
and windows, holes in a structure meant for wires, or through
wet, damaged wood. They will also crawl along overhead wires,
shrubs or tree limbs that touch the building far above the
ground. Carpenter ants build their nests in various wood sources
including tree stumps, fence posts, firewood or landscaping.
A colony can have multiple nests inside structures as well as
outdoors. Carpenter ants need a constant water source to survive.
THREATS:
Carpenter ants damage wood through their nest building.
Over time, an infestation can cause serious structural
damage to a property.
DID YOU KNOW? Carpenter ants…
• can live in mature colonies of more than 10,000 workers.
• first invade wet, decayed wood, but they may eventually build
paths through dry, undamaged wood.
• do not sting, but their bites can be quite painful.
