Carpenter ants in Arizona are among the largest ant species, ranging from 1/4 inch to 1/2 inch in length, with queens sometimes reaching up to 3/4 inch. They are typically black, though some species may appear reddish-brown or two-toned black and red. These ants have smooth, shiny, segmented bodies with a rounded thorax, a narrow waist, and elbowed (bent) antennae. Their strong mandibles can chew through wood, not for food but to create hollow galleries for nesting.
Winged carpenter ants, seen during swarming season, have two pairs of wings, with the front pair longer than the back, unlike termites whose wings are equal in length.
Carpenter ants primarily eat a diet rich in sugars and proteins, which they gather from various sources. Here’s a breakdown of what carpenter ants eat:
Carpenter ants are not dangerous to humans, as they do not bite or sting in a harmful way, nor do they spread diseases. However, they can cause minor to significant structural damage to homes and properties, making them a concern for homeowners.
Yes, carpenter ants tunnel through wood to build their nests, creating smooth, hollow galleries. Over time, this can weaken wood structures, including beams, floors, and walls. While they prefer water-damaged or decaying wood, carpenter ants will expand their activity into dry wood if necessary.
Carpenter ants often build their nests in moisture-damaged or decaying wood, as it’s easier for them to tunnel through. Common indoor nesting sites include:
Outdoors, these big ants will nest in the following places:
Carpenter ants thrive in damp or humid environments, even in dry climates like Phoenix. Leaky pipes, dripping faucets, and poorly draining irrigation systems create moisture-rich areas. Other factors that draw these ants in include:
These ants get into homes through tiny openings. Here are a few common entry points:
Homeowners may inadvertently bring them indoors in potted plants or other outside items.
These are nocturnal ants. The best time to look for them is at night. If you check areas where food sources are plentiful, like your landscape vegetation, you should see carpenter ant workers.
You should have no trouble telling them apart visually. Carpenter ants are dark-colored, large insects with pinched waists. Termite workers are pale-colored and about ⅛ of an inch in length. Looking closely, you’ll see that termites do not have pinched waists.
These two kinds of insects differ significantly in how they behave.
It is essential to know the differences between these two wood-damaging pests.

We've had Termio service since we moved into our current home and they treated this house for the previous owners, too. Never had issues with bugs or insects in the house at all. Service is always on time. Patty makes sure every time to thoroughly treat all areas around the house. Easy decision to stay with this service. Thanks.
