Carpenter Ant


How to exterminate them

The key to exterminating ants is to kill the entire colony. If you just spray the ants you see, more ants will continue to reappear in search for a source of water and food that they can bring back to share with the queen and other ants in the colony. Combat® products provide the source kill you need and are a guaranteed solution!

Where they live

Carpenter Ants are found throughout the U.S. The four common species are found in different regions of the country, but have similar habits and can be controlled using similar techniques. Carpenter Ants are most problematic for homes built in wooded rural areas.

What they look like

Carpenter Ants are large, ranging in size from 1/2 to 1 inch long. They range in color from yellow to black, although the most common species are dark.

Where they nest

Carpenter Ants usually nest in wood decayed by moisture or damage by other insects however they do not damage sound wood or eat wood, as their name implies. Hollow, moist wooden structures are prime nesting sites. Colonies usually have a single queen and as a result are smaller and take longer to grow. Mature colonies usually have satellite nests. While the parent nest is usually located outdoors in trees or stacks of fire wood, satellite nests are often located indoors in wall voids or other suitable locations.

What they eat

Carpenter Ants feed mostly on sugary liquids like honeydew from plant-sucking insects such as aphids, scales, and mealybugs and nectar from plants. However, they increase their consumption of protein in the summer and fall when reproduction is greatest. Carpenter Ants are nocturnal and forage for food strictly at night.

Steps to prevent an invasion

To protect your home from future infestations, replace damaged structural wood, repair water leaks and make sure ventilation is adequate to keep structural wood in your home dry and sound. Keep your yard free of decaying wood and trim plants back at least 1 foot away from your home. Seal cracks and crevices in exterior walls to keep ants from entering your home.
