Carpenter Ants

How Do Carpenter Ants Mate?

Carpenter ants will begin mating flights in a process called swarming. Winged males are typically the first to emerge when environmental conditions like temperature and extended daylight signify that it’s time to swarm. If conditions are right, the male releases a pheromone that stimulates the female to leave her nest.

What Do Carpenter Ants Eat?

Carpenter ants feed primarily on insect honeydew, plant and fruit juices, insects and other arthropods. Inside, they will also feed on sweets, eggs, meats, cakes and grease. The workers will forage up to 300 feet from their nest. Although some workers are active during the day, most activity occurs from shortly before dusk until dawn.

The reason sawdust is a clear sign of carpenter ants in the house is because they do not actually eat the wood. They only dig holes in the wood to make their nests.

How Big Are Carpenter Ant Colonies?

The western black carpenter ant colony, when mature, contains about 10-20,000 workers, with large colonies of more than 50,000 individuals. There is usually only one functional, wingless queen per colony. Swarmers are not produced until the colony is more than two years old. They are produced in the previous year and held over the winter in the nest for release the following year. Swarmers appear from May until August in the eastern United States and from February through June in the west.

How Do Carpenter Ants Enter Buildings?

Carpenter Ants usually come into buildings through cracks around doors, windows, or through plumbing and electrical penetrations in the home. They will also crawl along overhead wires, shrubs, or tree limbs outdoors that touch the building above ground, then enter the home through any small opening.

How Do You Find a Carpenter Ant Exterminator?

What Kind of Wood Do Carpenter Ants Attack?

Most species of carpenter ants attack wood that is or has been wet and damaged by mold. They prefer to attack wood softened by fungus, which is often associated with moisture problems, so homeowners should keep an eye out for excess moisture and soft, rotting wood around the home. Even though they first invade wet, decayed wood, they may later begin excavating tunnels through dry, undamaged wood.

Where Do Carpenter Ants Build Their Nests?

Carpenter ants build their nests outdoors in various wood sources. This can include:  

• Tree stumps 
• Rotting fence posts 
• Old firewood 
• Under stones 

The parent colony, or main colony, is typically located outside and contains the queen, eggs and young. Satellite nests can occur and branch out from the main parent colony, and they only contain workers, mature larvae, and pupae. Satellite nests are formed in mid-summer both indoors and outdoors and do not form until the parent colony matures over several years. Usually around August, the workers and winged ants will emerge from the pupae.
