Carpenter Ants Society and Lifecycle

Ant Control - Croach - Kirkland, WA - Winged Carpenter AntsAs the weather warms in early Spring, carpenter ant mating season begins. Winged males and females leave the nest.

Unique to carpenter ants, they mate in flight, the male dies, and the female loses her wings. She searches for decaying wood in which to lay her eggs.

In a few weeks, the young workers begin building new nests of tunnels and galleries in the wood.

A healthy colony will contain thousands of workers as the reproduction cycle continues and new nests are established.

Carpenter Ant Identification

Ant Control - Carpenter Ants - Croach - Kirkland, WA - Ant on orange backgroundIt is easier to tell the difference between carpenter ants and termites over any other ant species.

They have four wings – the back being shorter than the front. Termites also have four wings, but they are equal in size and shape, often extending beyond the length of their bodies.

Carpenter ants have distinctly bent (elbowed) antennae. Termites have straight antennae. Carpenter ants have a three-segmented body, pronounced waist, and six legs. Termites don’t really have a waist.

Carpenter ants range in size from just over an eighth, to around three-quarters of an inch in length. They vary in color; they can be black, red, brown, or yellow. The easiest way to identify an infestation is to look for piles of frass, which looks like fine sawdust.

What Senses do Carpenter Ants Possess?

Can they see?

Yes, with eyes similar to bees they can see in spectrums you cannot. They do have difficulty with certain shades of red light though. They are also sensitive to moonlight, not sunlight like other species, as they are mostly nocturnal.

Do they hear?

Yes, but not like you do. Carpenter ants are sensitive to vibrations, which they use to communicate.

Ants have up to eight times more scent receptors than other insects, making their sense of smell and taste exceptional. These receptors are used for multiple purposes, but are mostly dedicated to communication via pheromones.
