The Silent Invaders: How Carpenter Ants Destroy Vancouver Homes
Carpenter ants are among the most destructive pests homeowners can encounter, and in Vancouver’s damp climate, they’re especially problematic. These pests are silent invaders—causing significant structural damage long before you even know they’re there. Understanding how they operate, recognizing the early warning signs, and taking swift action can make all the difference in protecting your home.
What Makes Carpenter Ants Different?
Unlike termites, carpenter ants don’t eat wood—they tunnel through it to build their nests. Their name comes from this nesting behaviour. Over time, as these ants burrow through wooden structures, they weaken the internal integrity of beams, supports, and other structural elements. This makes carpenter ant removal not just a pest control concern, but a matter of home preservation.
Carpenter ants vary in size, typically ranging from ½ to ⅝ of an inch. While black is the most common colour, some species may appear red, brown, or even a combination. In Vancouver, the western black carpenter ant is most prevalent, with mature colonies housing tens of thousands of workers and one wingless queen.
Colonies take a couple of years to mature, and only then will they begin to produce winged swarmers—ants that leave the colony to start new nests. These swarmers usually appear between February and June in the West, often signalling that an infestation has been active for quite some time.
Signs of a Carpenter Ant Infestation
Spotting the ants themselves is often the first clue, but there are more subtle signs homeowners should be aware of. One of the clearest indicators is the presence of small holes in wood with fine, sawdust-like debris accumulating below. This material—sometimes mixed with bits of insulation and insect parts—is known as “frass” and is expelled by ants as they clean their tunnels.
Another telltale sign is the sound of faint rustling within walls, especially at night when carpenter ants are more active. If you hear tapping or soft crunching noises from inside your home’s wooden structures, it may be time to contact a licensed exterminator.
These ants are especially drawn to wood that has been weakened by moisture or fungus, making homes in Vancouver particularly vulnerable. Regularly inspect areas like basements, crawl spaces, window sills, and wooden decks—anywhere moisture may accumulate.

Carpenter ants don’t eat wood—they tear your home apart with it. Know the signs before it’s too late.
Prevention and Removal Strategies
Effective carpenter ant removal in Vancouver involves a combination of targeted treatment and prevention. Addressing moisture problems, sealing entry points, and replacing damaged wood are essential first steps. While DIY methods exist, they rarely eliminate the entire colony—especially if satellite nests have formed throughout the structure.
For long-term protection, homeowners should consider working with a professional exterminator who understands the specific challenges of residential pest control in Vancouver’s climate. Proper pest control involves more than just spraying an area—it includes inspection, monitoring, and strategic treatment to ensure the nest is completely eradicated.
