Carpenter
Ant
Characteristics –
Size: Up to 5/8-inch long.
Color: Varies from black, brown and black, red and black, to light
brown depending on the species. The two most common pest species are black in
color.
Behavior –
Carpenter ants feed on a wide variety of foods, especially other insects. The
favored food of adults is the sweet honeydew produced by plant-feeding insects,
such as aphids, scales, and mealybugs. In the spring, mature colonies produce
winged reproductive ants, called swarmers, that fly out to start new colonies.
These swarms often occur from satellite colonies within homes, so homeowners may
see large flying ants in their homes at night. Carpenter ants can be very
difficult to control, so most homeowners employ the services of a professional
company such as Carson.
Habitat – Carpenter ants are the most common pest ant seen
in homes throughout the northern United States. The main colony must have a
constant source of moisture to survive, so it is usually located in dead wood
outside. This includes dead limbs, tree holes, stumps, landscape timbers, and so
forth. Indoors, a main colony will have to be associated with a water leak or an
overly wet, poorly ventilated crawl space or attic. The main colony may establish
satellite colonies that are the primary source of ant activity inside homes.
These satellite colonies may be located in any suitable void (e.g., hollow
doors, curtain rods, shower rods), under attic insultation, etc. These ants set
up trunk trails between the main colony to satellite colonies and between
satellite colonies. Foraging ants can most easily be seen along these trunk
trails at night when the ants are most active. Sometimes, the trunk trails occur
beneath the ground following tree roots.
Tips for Control – Successfully controlling carpenter ants
requires certain skills, knowledge and experience. Carpenter ant control
involves tracking down and treating as many satellite colonies as possible
inside and outside of the home as well as attempting to find and treat the
parent colony. Accessing the parent colony may be difficult because it might be
located high in a tree or on a neighboring property. In such cases, your service
professional may use carpenter ant baits, but these may have varying results
because of the carpenter ants’ finicky feeding habits. If conditions on your
property (such as a large number of trees) create a high risk for reinfestation,
your service professional may recommend regular pest management services to help
prevent new infestations
These tips will help you limit carpenter ant infestation:
 | Store any firewood away from your home and remove any dead wood or wood
scraps from around the foundation.
|
 | Trim dead limbs from trees and remove stumps. Trim tree branches that
touch the walls or roof of the house.
 | Replace rotted or rotting landscape timbers and railroad ties.
 | Make sure that all plumbing or roof leaks are sealed, and check crawl
spaces for excess moisture.
 | Direct water from rain gutters away from your home and don’t allow it to
accumulate close to the foundation.
 | Keep gutters cleaned to prevent overflow into soffits.
 | Ensure that the crawl space and attic are well-ventilated.
 | Seal cracks and holes in the exterior of the home.
 | Change landscape plants to those that are less likely to support aphids or
employ a tree and shrub company to control these insects. Remember that ants
use aphids as a primary food source. |
