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.

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.

Good Afternoon, Mark came out to service our house on Monday, 10/01 at 11:00 and he was great! We got your name from the neighbor across the street who used your service and they were extremely happy so we thought we would give you a try and we are glad we did. After signing up for your service we had a little pet that decided to use our chimney for a family. That was when we met Scott & Nick – they were very professional and courteous of the interior of the house when they tried to extract good old “Rocky” Racoon from our chimney. Things went exactly as they thought they would and Rocky was gone by the next morning. Mark was just as knowledgeable, courteous, and professional as Scott & Nick so Colonial is batting 3 for 3 as far as we are concerned. We can see this being a long term relationship. Thank you and all the best to the business and your workers.
