Cover on carpenter ants

The carpenter ant Camponotus pennsylvanicus is the number one structural threat to wood buildings in Quebec. In Longueuil and the South Shore, our interventions mainly target the wooden triplexes of Old Longueuil and Saint-Hubert. In Brossard and sector DIX30, wooden houses in sectors A to R are affected mainly at the level of floor joists. Our South Shore carpenters service combines thermographic inspection and gel bait treatment. In Boucherville, Old Boucherville concentrates wet frameworks infested by dead tree stumps. Further east, in Saint-Jean-sur-Richelieu and the surrounding area, the open-frame heritage buildings of Old Saint-Jean require specific expertise. In Saint-Hyacinthe (Maskoutains), farmhouses and old buildings in the downtown area account for the bulk of annual cases.

Did you know?

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

Methods used for carpenter ant extermination

To get rid of carpenter ants in the long term, you need to eliminate the queen, which is the breeder of the mother colony and other satellite colonies that are in your home. You can place bait on the floors of the house that the ants bring to others as well as to the queen. An insecticide can also be applied to at-risk surfaces.

Nova Extermination’s specialized technicians will solve your problem quickly and sustainably. We offer our affordable carpenter ant extermination service in all cities on the South Shore of Montreal. We have mastered the techniques to carry out carpenter ant extermination, and we use insecticides approved by the Ministry of the Environment to solve the problem.

DANGER TO THE LOAD-BEARING STRUCTURE OF YOUR HOME

The carpenter ant is dangerous for the load-bearing structure of your home. Indeed, this insect chews through the wood to make galleries and build its nest in the floors, walls or attic of your home. Carpenter ants do not eat wood chips. They only dig into the wood of the framing beams, and then they reject the chips. The accumulation of wood chips in certain areas of your home can indicate the presence of carpenter ants.

TO PREVENT ANOTHER INFESTATION

Once our carpenter ant extermination has been carried out, it is then necessary to Caulking entry points through which ants could return: holes and cracks around doors, windows and floors; foundation cracks; telephone cables, etc.). Nova extermination technicians can, if desired, carry out 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 from the Commission des normes, de l’équité, de la santé et de la sécurité du travail (CNESST) to carry out the necessary caulking work. We are also protected by comprehensive liability insurance to carry out this work.


To prevent a new carpenter ant infestation, care must also be taken to replace rotten lumber while reducing humidity and water infiltration. It is also important to store food in leak-proof containers and keep floors and countertops clean, free of food seeds. Also be sure to cut tree branches that touch your house, and uproot old stumps. Also, check the firewood you bring into the house.

Frequently Asked Questions: Carpenter Ants

How to recognize a carpenter ant infestation?

Carpenter ants are among the largest in Quebec (6 to 13 mm), usually black, and leave behind small piles of fine sawdust (frass) resembling pencil shavings. They are often seen in the evening, and a faint rustling in the walls can betray their activity. In Saint-Bruno and Beloeil, they are common in houses surrounded by trees and damp wood.

Do carpenter ants eat wood like termites?

No, they do not consume the wood: they dig it to build their galleries and house the colony, favouring damp or already damaged wood. Over time, these smooth, clean galleries can weaken structural elements such as joists, window frames, or decks. It is this potential for wood damage that makes this species of particular concern.

Where do the carpenter ants that settle in my house come from?

They often first nest outdoors in stumps, dead trees, or damp firewood, and then establish satellite nests indoors in wood exposed to moisture. Water infiltration, roof leaks and wood in contact with the ground promote their installation. Reducing humidity is an essential part of control in Montérégie.

How is a carpenter ant treatment performed?

Our technician inspects the interior and exterior to locate the main nest and satellite nests, following the tracks and frass tracks. The treatment combines strategically applied registered products and baiting, with recommendations to correct moisture sources. Precisely locating the nests is crucial, which justifies the intervention of a professional.

What is the cost of a carpenter ant treatment?

The price is established on the basis of an evaluation, depending on the extent of the situation, the location of the nests and the extent of the wood affected. Since the inspection may reveal multiple homes, a fixed amount cannot be given in advance. The technician will present you with the price before the work, as all our services are subject to a fee.

Can you guarantee that carpenter ants won’t come back?

We aim for sustainable results evaluated on a case-by-case basis, because the return also depends on factors such as humidity and the proximity of dead wood on your property. Eliminating nests and correcting favourable conditions greatly reduces the risk of recurrence. Our technician advises you on the corrections to be made to the building rather than promising an absolute warranty.

Foire aux questions

Nova Extermination intervient partout sur la Rive-Sud et à Montréal pour éliminer souris, rats, fourmis, punaises de lit, coquerelles, guêpes et autres nuisibles. Voici les questions les plus fréquentes sur nos services d'extermination.

Combien de temps faut-il pour exterminer une infestation de souris ?

La durée varie selon l'ampleur de l'infestation. Une intervention typique sur la Rive-Sud commence par une inspection complète, suivie de la pose de pièges et d'appâts ciblés. La plupart des infestations de souris sont maîtrisées en deux à quatre semaines, avec une ou deux visites de suivi. Nova Extermination repère ensuite les points d'entrée et procède au calfeutrage des trous, ce qui empêche les rongeurs de revenir. Les travaux d'extermination de rongeurs sont garantis cinq ans.

Quels types de nuisibles Nova Extermination peut-il traiter ?

Nos techniciens certifiés traitent une large gamme de nuisibles : souris, rats, fourmis, punaises de lit, coquerelles, guêpes, abeilles, araignées et autres insectes, ainsi que les petits animaux comme les ratons laveurs, les mouffettes, les marmottes, les chauves-souris et les oiseaux. Que le problème se trouve dans une maison, un appartement, un commerce ou un bâtiment institutionnel à Montréal ou sur la Rive-Sud, nous avons l'équipement et l'expérience pour régler la situation à la source.

Les produits utilisés sont-ils sécuritaires pour les enfants et les animaux de compagnie ?

Oui. Nova Extermination utilise des produits homologués et applique des méthodes ciblées qui réduisent au minimum l'exposition. Nos techniciens placent les appâts et les traitements dans des endroits stratégiques, souvent hors de portée des enfants et des animaux. Avant chaque intervention, nous expliquons les précautions à prendre et le délai à respecter avant de réintégrer les pièces traitées, afin de garantir la sécurité de votre famille.

Que dois-je faire pour préparer mon domicile avant l'arrivée de l'exterminateur ?

La préparation dépend du type de nuisible. Pour les punaises de lit, il faut généralement laver et sécher la literie à haute température et dégager les espaces autour des lits. Pour les coquerelles ou les fourmis, il est utile de nettoyer les surfaces de cuisine et de ranger les aliments. Lors de la prise de rendez-vous, notre équipe vous remet des consignes précises adaptées à votre situation pour maximiser l'efficacité du traitement.

Offrez-vous un service d'urgence sur la Rive-Sud et à Montréal ?

Oui. Nous savons qu'une infestation peut devenir préoccupante rapidement, surtout dans le cas des rats, des punaises de lit ou des nids de guêpes. Nova Extermination dépêche un technicien dans les meilleurs délais.

Le service d'extermination est-il garanti ?

Cette garantie reflète notre approche complète : nous ne nous contentons pas d'éliminer les nuisibles présents, nous nous attaquons à la source du problème et bloquons les points d'entrée.
