When to Watch for Ant Infestations in Coquitlam
In Coquitlam, ant activity doesn't follow a strict summer-only pattern. Thanks to our high rainfall, forest proximity, and humid indoor environments, ants remain active much longer — and sometimes all year round. Knowing when to watch for infestations helps you stay ahead of them.
Spring (March to May): Colonies Reactivate
•Carpenter ants begin swarming and establishing new nests.
•Moisture ants and odorous house ants trail from soil and rotting wood into homes.
•Outdoor activity increases as rainfall softens the soil and triggers foraging.
Signs to watch for:
•Flying ants near windows or ceiling lights
•Trails forming along baseboards or wall edges
•Piles of sawdust (frass) near window frames or attic vents
Summer (June to August): Peak Indoor Invasions
•Ants enter through patios, under siding, and through concrete cracks.
•Warm, wet conditions drive colonies indoors for food and shelter.
•Multi-unit buildings may experience pharaoh ants spread between walls and floors.
Signs to watch for:
•Persistent ant trails in kitchens and bathrooms
•Activity near pet bowls, food bins, or garbage
•Ants emerging from vents, pipes, or wall outlets.
Fall (September to October): Ants Seek Shelter
•Cooler nights and heavy rain push ants indoors for warmth.
•Colonies migrate deeper into wall voids, under floorboards, or into attic insulation.
•Home heating systems may attract ants to basements and boiler rooms.
Signs to watch for:
•Increased sightings around plumbing and heating fixtures
•Movement near electrical panels or wall junctions
•Renewed activity even after DIY treatment
Winter (November to February): Indoor Colonies Stay Active
•Heated homes, especially with radiant floors or damp basements, support year-round colonies.
•Pharaoh, odorous, and carpenter ants can continue nesting and reproducing inside.
Signs to watch for:
•Sporadic sightings of ants in kitchens or laundry rooms
•No outdoor trails, but indoor activity persists.
•Ants appearing during or after rainfall
Crawlspace homes and homes near trails or wooded ravines (like those in Burke Mountain or Riverview) are at higher risk of winter activity — especially in homes with high indoor humidity.
Whether it's spring swarms or winter wall nests — Pesticon is ready. Call today for seasonal ant protection tailored to Coquitlam's climate and housing.
Homes and Businesses We've Helped in Coquitlam Stay Ant-Free
Every Coquitlam property is different — but whether it's an older home in Maillardville, a new build on Burke Mountain, or a storefront on Austin Avenue, the ant problems are often the same: hidden nests, persistent trails, and ineffective DIY treatments. At Pesticon, we bring local expertise and proven methods to every job and stand by the results. Here are a few real-world examples from across Coquitlam:
Burke Mountain Detached Home — Carpenter Ant Infestation
Problem:
The homeowner noticed clicking sounds in the ceiling and piles of fine wood shavings near a skylight. A previous roof leak had created damp framing.
Our Solution:
We identified a carpenter ant gallery in the attic joists, applied a non-repellent treatment, and sealed ventilation gaps after drying the area.
Result:
Structural damage was stopped early, and the home has remained ant-free for over a year with seasonal inspections.
Maillardville Townhouse — Pharaoh Ants in Shared Walls
Problem:
Tiny ants were found in multiple units — especially around kitchen outlets and bathroom fixtures. Strata residents had used repellent sprays, which scattered the colonies.
Our Solution:
We worked with building management to deploy slow-acting baits inside plumbing and electrical chases across affected units.
Result:
The colony was eliminated without further spread. No reappearance after three months of follow-up.
Westwood Plateau Restaurant — Pavement Ants in Prep Area
Problem:
Ants appeared near the tile seams around the dishwasher and garbage station, especially during and after heavy rain.
Our Solution:
We treated the foundation perimeter, sealed interior slab cracks, and placed tamper-proof bait near vulnerable zones.
Result:
The business passed inspection with zero pests, and we now provide quarterly service to maintain compliance.
Austin Heights Heritage Home — Odorous House Ants in Walls
Problem:
Strong smell in the kitchen and consistent ant trails around the pantry and window ledges.
Our Solution:
We traced scent trails back to wall voids, baited strategically, and sealed exterior entry points near the window trim.
Result:
The scent and ants are gone, and the homeowner signed up for ongoing seasonal coverage.

Why Ant Infestations Are a Common Problem in Coquitlam
Coquitlam's natural setting — from rain-soaked mountainsides to wooded neighbourhoods and high water tables — makes it a prime location for ants to thrive. Combine that with older home structures, new development zones, dense parkland, and an ideal environment for ants to multiply and move indoors. Here's why ant infestations are so common in Coquitlam homes and businesses:
High Rainfall and Moisture Levels
Coquitlam receives over 1,100 mm of rain annually. That persistent moisture leads to:
•Damp crawlspaces and basements
•Wet attic framing
•Soil saturation around foundations
This attracts ants — particularly carpenter and moisture ants — who nest in softwood and move indoors to escape flooding.
Forested and Greenbelt Exposure
Neighbourhoods like Burke Mountain, Westwood Plateau, and Riverview back onto dense forests, trails, or green space. While beautiful, these surroundings are full of outdoor colonies.
•Pavement ants and Argentine ants enter through cracks near patios and decks.
•Homes near Mundy Park and the Coquitlam River report higher-than-average indoor infestations
Fact: Properties within 500 metres of large green spaces in Coquitlam are 40% more likely to report recurring ant problems.
Older Housing Stock and Construction Gaps
Areas like Maillardville and Ranch Park feature homes built before modern sealing and insulation standards. These homes are more vulnerable due to:
•Wood siding and open crawlspaces
•Unsealed vents, eaves, or utility penetrations
•Leaky plumbing behind walls or under floors
These hidden spaces provide long-term nesting zones for ants — especially in winter.
New Construction = Displaced Colonies
Coquitlam continues to expand, particularly in Burke Mountain and West Coquitlam. As trees are cleared and soil disturbed, ants are forced to relocate—often into nearby homes and townhouses.
•Newly built homes may have construction gaps or soil-borne colonies nearby.
•Developers often leave behind unsealed entry points and untreated framing.
Year-Round Activity in Heated Homes
•Coquitlam's mild winters don't stop ant colonies from growing inside heated homes.
•If ants have already established themselves in a wall, crawlspace, or attic, you may see signs in every season — including December and January.
At Pesticon, we don't treat Coquitlam the same way we do the rest of Metro Vancouver. We tailor every job to your specific neighbourhood, house type, and climate challenges — using real data, real inspections, and real results. Think your home is safe because it's winter? Think again. Contact Pesticon today for ant control built for Coquitlam.
Types of Ants Our Coquitlam Ant Exterminators Handle
Different species of ants behave in very different ways — and require different strategies to eliminate. At Pesticon, our licensed exterminators begin every Coquitlam job with proper identification so we can deliver safe, targeted, and permanent results. Here are the most common ant species we treat in the city:
Carpenter Ants
The most destructive ant species in Coquitlam. Carpenter ants tunnel through wood to build nests — often in damp attics, crawlspaces, and wall framing.
Pharaoh Ants
Tiny, yellowish ants form large colonies and spread rapidly through multi-unit buildings — especially where plumbing and heat sources converge.
Moisture Ants
These ants don't damage structures but are often signs of larger moisture issues. They're drawn to decaying wood, mouldy insulation, or dripping plumbing.
Odorous House Ants
When crushed, these small brown ants emit a strong, rotten smell and often invade kitchens and bathrooms for sweets and water.
Pavement Ants
Ground-nesting ants that move into homes through cracks in sidewalks, patios, and foundation slabs — especially after rain.
DIY Ant Control vs. Professional Ant Extermination in Coquitlam
It's easy to underestimate how serious an ant problem can become — especially if you only see a few ants on the counter. While DIY methods may offer short-term relief, they rarely address the colony, the moisture source, or the entry points. In Coquitlam homes, that almost always means the ants return.

Why DIY Usually Falls Short in Coquitlam
•Moisture ants and carpenter ants often live behind walls or in crawlspaces where store-bought sprays can't reach.
•Pharaoh ants can split into multiple colonies if sprayed with the wrong product.
•Most bait products aren't designed for long-term colony elimination and must be carefully placed in the right areas.

•Our exterminators are trained to identify and treat the specific species — no guesswork or over-spraying.

DIY Ant Extermination Guide for Coquitlam Residents
If you're dealing with a minor infestation and want to try solving it yourself, it's essential to do it carefully — especially in Coquitlam, where high rainfall, wood-framed homes, and elevated humidity allow ant colonies to survive in deep, hidden spaces. Here's a step-by-step guide to DIY ant control in Coquitlam:
1
Identify the Ant Species
Different ants require different strategies.
•Large black ants in or near wood? Likely carpenter ants
•Small brown ants near sugar or water? Odorous house ants
•Tiny pale ants trailing from outlets or plumbing? Possibly pharaoh ants
•Trails from patios, sidewalks, or under baseboards? Pavement ants
•Ants in bathrooms or damp corners? Likely moisture ants
Tip: If you are unsure about the species, take a photo and contact a local expert (like Pesticon) to confirm it.
2
Locate the Trails and Entry Points
Look closely at:
•Baseboards, electrical outlets, and plumbing fixtures
•Window and door frames, especially in kitchens and bathrooms
•Crawlspace access points or attic hatches
•Exterior foundation cracks, mulch beds, or tree limbs touching the house.
Tip: In Coquitlam homes, standard hidden entry zones include wood siding, crawlspace vents, and cracks in garage floors.
3
Remove Attractants
Ants are drawn to food and water sources. Cut them off by:
•Cleaning kitchen counters and floors thoroughly
•Storing food (especially sweets and pet food) in sealed containers
•Wiping surfaces with vinegar or lemon water to break scent trails
•Fixing leaking pipes, faucets, or downspouts
•Running a dehumidifier in damp basements or crawlspaces
4
Use the Right Bait
Skip the over-the-counter spray — which may kill visible ants but not solve the colony problem.
•Use sugar-based bait for odorous or pharaoh ants.
•Use protein-based bait for carpenter ants.
•Place bait near trails but away from cleaning products (which mask scent)
Important: Do not mix repellent sprays with bait stations; this will prevent the bait from reaching the colony.
5
Monitor Activity and Be Patient
•Let the ants take the bait back to the colony
•Avoid cleaning trails too soon — ants need time to carry bait.
•Monitor bait stations every 2–3 days and replenish if needed.
•Depending on size and species, colonies can collapse fully for 7 to 14 days.
6
Seal Up Entry Points
Once activity subsides:
•Caulk cracks and gaps around windows, doors, and siding
•Install door sweeps and weather stripping.
•Trim back branches or shrubs that touch exterior walls.
Tip: In Burke Mountain and Ranch Park, scrutinize wood siding and decks, which are common entry points.
7
Know When to Call a Professional
If ants return within 2–3 weeks or see activity in winter or multiple ant types, you're likely dealing with a larger or hidden colony.
DIY methods can work — but they require attention, consistency, and a good understanding of local ant behaviour. In Coquitlam, that often means dealing with hidden moisture and complex house structures that make professional help the safer, more effective choice.

Ant problems in Coquitlam aren't random. They're shaped by the city's wet climate, wood-heavy construction, and proximity to parks, creeks, and forested slopes. At Pesticon, we analyze the trends to serve our customers better — and we want you to understand the risks where you live.
Carpenter Ants Are the Most Reported Structural Pest in Coquitlam
•Carpenter ants are the top complaint in neighbourhoods with older homes and heavy rainfall.
•Especially common in Burke Mountain, Ranch Park, and homes near Riverview Forest.
Fact: Over 65% of Pesticon's service calls in Coquitlam for structural damage involve carpenter ants nesting in attic framing, wall cavities, or crawlspaces.
Homes Near Green Spaces Have Higher Recurrence Rates
Trails and forest borders allow outdoor colonies to thrive and easily enter nearby structures.
High-risk areas include homes near:
•Mundy Park
•Coquitlam River
•Como Lake
•Riverview Forest
•Westwood Plateau Trail system
Fact: Homes within 500 metres of an enormous greenbelt or natural park are 35–50% more likely to report recurring indoor ant infestations.
Year-Round Indoor Ant Activity in Heated Homes
•While many homeowners expect ants to disappear in winter, indoor colonies remain active in Coquitlam's mild coastal climate.
•Radiant heating, warm crawlspaces, and humid bathrooms allow colonies to remain undetected and growing.
Fact: Pesticon receives ant-related service calls in Coquitlam every month of the year — even in January and February.
Multi-Unit Homes and New Builds See Pharaoh and Pavement Ant Activity
•Ants often travel through shared plumbing lines and utility chases in townhouses and condos.
•New Burke Mountain and West Coquitlam construction sites displace colonies into nearby homes.
Fact: Over 40% of pharaoh ant cases in Coquitlam come from strata-managed buildings with no previous pest control plan.
European Fire Ants (Emerging Threat)
•Sightings of aggressive, stinging ants have been reported near wet gardens and lawns.
•While rare, fire ants have been confirmed in parts of Anmore and southern Coquitlam near wooded trails.
