Carpenter Ants Headache or Nightmare?

Getting to Know Carpenter Ants


The black Carpenter ant, Camponotus Pennsylvanicus, is the most common species of Carpenter ant in the Eastern United States. Workers range in size from to inch ( 6-13 mm) or more in length. Carpenter Ants farm aphids and other honeydew secreting insects, lapping the honeydew juices from them.


Could You Have Carpenter Ants?

A common sign of Carpenter ant infestation is the sight of sawdust falling from window or door frames. As these ants tunnel into wood to nest, they push out the sawdust; they do not digest wood as termites do. Additionally, Carpenter ants may be heard making a crackling noise in walls when the house is quiet. This noise is generated by their mandibles (jaws) chewing on wood. Tapping the wall usually increases the noise.

Where Carpenter Ants Frequent

Infestation Areas Inside

In addition to window and door frames, common infestation areas within a building include:

  • Sills (wooden sill plates for stud walls)

  • Hollow-core doors

  • Inside dishwashers for moisture

  • Under toilets

  • Above and/or behind insulation

  • In entry door encasements

  • In sliding window shoe and door encasements

  • Under wall-to-wall carpets, along the tack strips

  • In garage door jambs

  • Under siding

  • Behind the front entrance

  • Along eaves and gutters and rake boards

  • Between the flashing and fireplace

  • In skylight encasements

Where Carpenter Ants Frequent

Infestation Areas Outside

Common infestation areas outside a building include:

  • In or under entrance columns

  • In ground nests

  • In septic leach fields

  • In railroad or landscape ties

  • In and around wood piles

  • In tree stumps

  • In or around porches and decks

  • In hollow porch columns

  • In telephone poles. They can then travel along the wires to enter the building.

  • In wood chips (mulch around the house)

  • In trees. Suspending a dog line between a tree and a house can provide entry to the house just like a telephone wire.

The Making of a Colony

The colony usually starts with one queen, which has either nested outside close to the house or, possibly, inside the house, and usually has bored a tunnel in wood where she will lay her eggs.

Moisture and damp wood provide Carpenter ants ideal nesting conditions.

Mature Carpenter ant colonies can produce as many as 2,000 or more ants.

Multiple colonies within a radius of 50 yards of homes are common.


Homeowner Control Tips


You can help control carpenter ants around your home by using these preventative measures:

  • Reduce the overall amount and volume of garden mulch used

  • Replace landscape ties that have rotted

  • Keep tree limbs cut away from the house

  • Repair leaks promptly

  • Use crushed stone around the foundation

Carpenter Ant Eradication

Baits are a Good Option

Controlling Carpenter ants is important, as the damage they cause can be costly and extensive.

Advances made in the last several years have included the introduction of Carpenter ant baits. These controlled substances are meant to be applied to cracks and crevices or placed in wall voids. The baits are very effective when placed around nesting carpenter ants. The ants take the bait back to the nest, regurgitate, and feed the bait to others.

Additional control options may be used along with baits to achieve the desired level of control. There are times when the homeowner may need to make repairs or follow recommendations in order to aid long term control.
