Did you know?

Carpenter ants do not eat wood! As one might imagine, carpenter ants destroy wood with their mandibles to expel it from their tunnels. This considerably affects the structure of the wood, in other words, that of your home.

Methods used for extermination of carpenter ants

To get rid of carpenter ants on a long term basis, you must eliminate the queen, which is the breeder of the mother colony and of the other satellite colonies that are in your house. Bait can be placed on the floors of the house, which the ants bring to others as well as to the queen. You can also spread an insecticide on your surfaces at risk.

Nova Extermination’s specialized technicians will solve your problem quickly and durably. We offer our carpenter ant extermination service at an affordable price in all cities of the South Shore of Montreal. We have mastered the techniques to exterminate carpenter ants, and we use insecticides approved by the Ministry of the Environment to deal with the problem.


The carpenter ant is dangerous for the supporting structure of your home. Indeed, this insect nibbles wood to make galleries and build its nest in the floors, walls or attic of your house. Carpenter ants do not eat wood chips. They just dig into the timber for the structural beams, and then they throw out the shavings. The accumulation of wood chips in certain areas of your home can indicate the presence of carpenter ants.


Once our carpenter ant extermination is complete, we must then caulk the entry points through which the ants could return: holes and cracks around doors, windows and floors; foundation cracks; telephone cables, etc.). Nova extermination technicians can, if desired, perform this caulking for you. Our company has a license in good standing from the Régie du Bâtiment du Québec (RBQ: 5734-75930-01) as well as the Commission des normes, de l’énergie, de la santé et de la sécurité du travail (CNESST) to carry out necessary caulking work. We are also protected by full liability insurance to perform this work.

To prevent a new infestation of carpenter ants, care must also be taken to replace rotten lumber while reducing humidity and water infiltration. It is also important to store food in airtight containers and to keep floors and counters clean, free from food seeds. Also, be sure to cut off any tree branches that touch your house, and to uproot any old stumps. Also check the firewood as you enter the house.

Information about the carpenter ant

It is important to be able to tell the difference between each type of ant. Carpenter ants are one of the most harmful to your environment, as they can do costly damage to your home. Carpenter ant extermination should be done at the first sign you see.


Carpenter ants are 6-25mm (up to 1 inch) long, with bodies divided into three parts. Their antennae are arched and segmented. Both male and female adults are winged upon mating. Carpenter ants are predominantly black in color, but can also be brownish or black with tints of red.


a colony can consist of more than 2000 ants after 3 years. The main nest is usually outdoors, while satellite nests are found inside buildings that are heated in winter. Ants move inside to gain access to human food. Carpenter ants crave protein and sweet foods. This is why they are most often found in kitchens.


When you see a carpenter ant wandering around your house, it may have come in to look for table food (seeds) left on the ground or in the pantry, and then return outside until his nest. But it is also possible that it returns to a nest that is installed in a corner of your house. If ants are in your house during winter time, it is certain that they have built a nest or even several nests there. Otherwise in winter, carpenter ants that are outside go into diapause, which is like a deep sleep, without almost no state of activity.
