There are a few important steps for successful Carpenter Ant Control.

1. Entry Points:
2. Exterior Structure:
3. Landscaping:
4. Treating the outside your home:
5. Treating inside your home:
6. Sanitation:

Entry Points:

Sealing all entry points is vital;

With out this step done thoroughly one may expect carpenter ants to continually re-enter your home. Although it might be impossible to completely seal your home, sealing key areas will help.

Adding caulking around windows and doorframes, ensuring you has tight closing doors and windows. Sealing any gaps around service wires or pipes entering your home.

If your home has brick vent gaps, those are the gaps in the mortar between your bricks usually running along the bottom course of bricks about knee high, these should not be filled rather screened. Use a small enough gage hardware cloth to prevent the worker or queen carpenter ant from entering.

If your house has vinyl or aluminium siding that will be more difficult as there are gaps through out the installation. This is where an exterior spray treatment will prevent carpenter ants from entering.

Exterior Structure:

Carpenter ants use tree branches and bushes as their highway as they are natural paths to follow. Removing vines off your exterior walls and keeping tree branches and shrubs a good distance from your exterior walls will stop those transient worker ants from discovering a new home for their expanding colonies.

Removing any clutter or woodpiles away from your exterior walls will help also.


Cutting grass and Trimming bushes, cutting down dying trees and removing any old tree stumps will aid in reducing the number of carpenter ant colony harbourage sites. Keeping the grass trimmed will help one to discover any under ground colonies that have harboured in an old tree under ground stump.

Also removing fallen fruit piles of rotting vegetation and removing water sources from your yard will also help make your yard less attractive to these colonies.

Treating the outside your home:

The exterior treatment involves the use of non-repellent chemicals around the foundation.

These safe, low-toxicity materials will be applied on the exterior of your house to act as a barrier preventing Carpenter Ants from entering your home through cracks and gaps. This material will be picked up by the ants as they travel from the structure and their feeding grounds outdoors.

As this material is trans-located back to the nest, the colony begins to suffer the effects from this chemical. And within a sort time, most of the ants will have been killed off causing the colony to collapse.

Treating inside your home:

The interior should also be treated to expedite the colony's collapse. As the colony starts to suffer the effects of the treatment the foraging ants will all die off as they are the first to come into contact with the spray treatment, then other works will begin to emerge from the colony in search of food and they in turn will die off from the effects of the treatment.

An interior treatment with These safe, low-toxicity materials will be applied only to structural areas such as baseboards, window and doorframes and any voids that are available such as drop ceilings and attics.


Keeping your homes sanitation levels heightened during treatment will help greatly as the reduction of food sources will force the carpenter ant to extend their search radius and duration exposing them to the treatment for a long time.

Pet food should be removed after your pets feeding times and not left out during the evening.

Pet food is a perfect and desired food source for ants as it contains proteins and carbohydrates perfect for a growing ant colony as the colony craves both these at different stages of their growth.


Carpenter ants are some of the biggest ants you'll see around your property. Typically, it's a large black ant. Carpenter ants aren't all large, though. Within a colony, there are different sizes of ants depending on the job they have to do, including the king and queen ants.


All black Workers 1/4-1/2-inch in size.

Queen: Large, over 1/2-inch in size.

The queen carpenter ant is just a largest of the ants in the colony with two smoky brown wings. Once the queen mates with the smaller wasp-like male, she'll chew her wings off, so you'll see little stubs of the wings.

But those are typically the biggest ants you'll ever see. If you step on them, all these white eggs come out the back, so that's how you will know it is a queen ant.

Workers are wingless, dark shiny brown to black in color, and 1/4 to 1/2 inch in length.

Winged reproductive forms resemble workers in color and shape but are up to 3/4 inch long.

The body is constricted between the thorax and the abdomen.

The antennae are elbowed.

The front wing of a reproductive ant is longer than the hind wing.

General Information

Carpenter Ants are nocturnal.

Swarming: Colony matures in 3-4 years, they spread out to establish a Satellite Colony.

Swarming occurs in late spring/summer.

They prefer to hollow out their nests in softened wood, such as moist or partially decayed wood.

Their nests are called galleries. These galleries are clean and have a sandpaper appearance.

In comparison, Termite galleries are rough looking. Wood that has been damaged by Carpenter Ants contain no mud-like material, as is the case with Termites.

Carpenter Ant nests can be found indoors in such places as the moist, hollow wall void behind dishwashers.

Nests are usually found in areas where water leakage could occur, such as around bathtubs, sinks, roof leaks, poorly-flashed chimneys, or poorly sealed windows or door frames.

Outdoor nests are found in places like tree stumps, hollow logs, fence posts, or dead portions of standing trees. However, these persistent creatures have even been known to build nests in cracks and crevices of sound wood.

Carpenter Ants may establish nests in a number of different locations. It is important to understand that you can have both inside and outside nests.

Carpenter Ants construct two different kinds of nests: parent and satellite colonies. Parent colonies, when mature, contain an egg-laying queen, a brood, and 2,000 or more worker Ants.

Satellite colonies may have large numbers of worker Ants, but contain no queen, eggs or larvae. For example, the Ants found in your home may have originated from parent nests outdoors, perhaps in a tree stump, timber or woodpile, or from one or more satellite nests hidden behind a wall in the kitchen or bathroom, or perhaps from wood dampened by a roof leak in the attic.

Although large Carpenter Ant colonies can cause structural damage, the damage is not normally as serious as Termite damage.

Carpenter Ant Diet


Carpenter Ants feed on protein-based foods (such as living and dead insects) and sweet-based foods (such as the honeydew produced by aphids and certain scale insects).


Carpenter Ants feed on pretty much anything they can find. Often, the Ants you see inside your home are simply foraging for food, and you may not see large numbers of them.

Most foraging is done at night between sunset and midnight during the spring and summer months. Sometimes workers travel up to 100 yards from a nest in search of food.
