Carpenter Ant Control


  1. The most important part of any Carpenter Ant treatment is to locate and eliminate the nest. Using our micro-injector machine we can flush out ants to find the nest and effectively eliminate the nest without having to open up wall or ceiling voids.
  2.  All treatments include a targeted application using low-impact materials:  This includes a thorough exterior treatment to the foundation and other potential entry points. An interior crack & crevice application, as well as placement of specially formulated baits
  3.  All work comes with a warranty. Which includes call-backs at no additional charge.

One way or another you can count on Colonial Pest to eliminate your ant infestation

Colonial Pest Control has been providing expert carpenter ant control services since 1984. We maintain a team of highly trained technicians who employ effective, low impact, low toxicity treatment methods to take care of your ant invasion problem.

Carpenter ants are found all over the world, but they are recognized as the number one wood destroying pest in New England and cause more damage to structures than termites. There are several species of these ants that may be infesting and damaging buildings and homes. The most common one in the New England area is the black carpenter ant. They achieve a size between ¼” to ½” (0.6-1.3 cm) and are most active during the night hours.

These large ants prefer dead and damp, decaying wood in which they make their nests. They cut tunnels called galleries into the wood to provide passage to and from the nest. They do not eat the wood but cut through it to expand the size of the nest, usually in a direction parallel to the grain. Their diet consists of sources of proteins, sugars and honeydew, which is a liquid that is produced by aphids and other scale insects.

In the spring, carpenter ants colonies produce “swarmers” which are the reproductive winged ants that take flight in order to establish a new colony. They are often mistaken for termites, but in either case the appearance of swarms of black ants with wings is a good indication that you need to find an experienced carpenter ant control or termite extermination service immediately.

There are several signs that your home or business may have a carpenter ant infestation. The first sign may be the sighting of flying ants or large black worker ants roaming about the home; sometimes they have bits of material that they are carrying in their mandibles. These ants are foraging and will often travel over one hundred yards from their nest in search of food.

Another indication that you need to contact a trained and certified carpenter ant control service is the appearance of material called “frass”, which looks like sawdust and may contain insect parts and bits of soil. This is usually found underneath nest openings and is the result of the tunnels that are bored into the wood by the ants. When you notice this material, which could indicate a nest site, tap against the area with the end of a screwdriver or plastic mallet. It may sound hollow and also listen carefully for clicking sounds which are the response made by alarmed ants.

80% of the carpenter ants in a colony never leave the nest, so total elimination of the problem depends on finding the ant colony. Our technicians are trained to find the nests, which generally occur in wall and ceiling voids where moisture problems exist. We rely on the Microgen Micro-injector to help us locate, flush and kill the colony.

All of our carpenter ant control work is warranted. We offer one time initial clean-outs and ongoing preventive maintenance programs to keep carpenter ants from returning and destroying the value of your home.

Today Jim came out to my house for my first visit to treat for carpenter ants. Not only was he very nice, he is extremely knowledgable about his job! I did not have too many questions for him, since your website is very detailed, but he still went over the procedures with me, and really made me feel like he was going to solve my problem TODAY. He managed to find the nest within a very short time, and went to work to destroy it. I was very pleased, and my 4 kids all cheered this evening when I said “The Ant Guy killed the Queen!” Jim did an excellent job, and I will be sure to request that he come back to do my regular service. THANK YOU Colonial Pest and THANK YOU Jim!
