What Do Carpenter Ants Look Like?

Carpenter ants are one of the largest ants in Texas and the United States, typically as small as 1/4 of an inch in length.  Queens of this species are approximately 9/16 inch long.  Carpenter ants vary in color and may appear dull black, brown, red or a combination of the colors.

Why Do I Have A Carpenter Ant Problem?

Carpenter ants often make their way into residential and commercial structures in order to excavate galleries within insulation and wall voids and possibly to forage for sweets, grease, meats and eggs.  Outside, they are often found in old firewood, rotting fence posts, stumps and dead portions of living trees. They can even be found under stones and logs.

Where Do Carpenter Ants Nest?

Carpenter ants will nest both indoors and outdoors, they will nest inside of wood that is hollow, wet, moldy, or decaying. Outdoors carpenter ants can be found nesting in tree stumps, fallen logs, firewood, and other landscaping; inside they will nest in water damage wood found behind walls and underneath of flooring. The carpenter ants will create smooth, clean tunnels in the grain of wood; the tunnels that they create allow the ants move safely from one area of the nest to another.

It is important to remember that carpenter ants only use wood to nest in, not to feed on; like other ant species they will create their nesting areas close to their food sources (particularly liking to feed on sweets and meats).

What Kind Of Threat Do Carpenter Ants Pose?

Carpenter ants pose a serious threat to structures in Texas as they hollow out the wood making it unstable.  They can cause painful bites should they come into contact with humans.

What Are The Signs Of A Carpenter Ant Infestation?

One of the main signs of a carpenter ant infestation is to see large ants in your home, particularly in kitchen and pantry areas where they are foraging for food. You also may notice them outside your house especially around areas of moisture like outdoor water fixtures, moist landscaping, or where trash is being stored. If carpenter ants have invaded your home you may hear “rustling” or “crackling” sounds from behind your home’s walls as they work.

Another sign that commonly alerts homeowners that carpenter ants are present is an ant swarm, a carpenter ant swarm occurs when the winged reproductive members of a mature carpenter ant colony leave the colony and “swarm” together looking to mate and establish a new colony.
