Carpenter Ant

There are nine types of carpenter ants throughout the U.S. and range in size from one-quarter inch (about the width of a pencil) for a worker carpenter ant to three-quarters of an inch (about the size of a quarter) for a queen carpenter ant.

Each colony is established by a single, fertilized queen. She starts her nest in a cavity in wood, where she raises her first brood of workers. She feeds them saliva and does not leave the nest or feed herself during this time.

When they are ready, those workers then get the job of gathering food to feed the next generation. Once mature, this first generation of worker ants work to increase the food supply for the colony. The colony population grows very rapidly. A colony can eventually produce 2,000 or more workers.

Carpenter ants do not eat the wood they remove during their nest-building activities, but deposit it outside entrances to the colony in small piles. The diet of carpenter ants includes living and dead insects, meat, fats and sugary foods of all kinds, including honeydew and nectar from plants.

Carpenter ants build nests anywhere they can find water and moldy or damp wood, such as tree stumps, firewood or in the plants around your house. Carpenter ants also build nests inside, usually entering buildings through wet, damaged wood, although it isn't uncommon for them to adapt to drier environments.

Carpenter ants don't carry disease, but when building a nest inside a home, Carpenter Ants dig smooth tunnels inside the wood. These tunnels weaken the wood and potentially damage the wood that keeps the house standing. This kind of damage can be very expensive to fix.

Eliminate standing water. Pests, such as ants, mosquitoes and termites, are attracted to moisture. Keep tree branches and other plants cut back from the house. Sometimes pests use these branches to get into your home. Make sure that there are no cracks or little openings around the bottom of your house. Sometimes pests use these to get into your home. Make sure that firewood and building materials are not stored next to your home. Pests like to build nests in stacks of wood.
