If you have a dog or cat in Maple Ridge, Pitt Meadows, or Langley, flea season is something you need to take seriously. The Fraser Valley’s mild, humid climate creates ideal conditions for fleas — and once they’re inside your home, they’re notoriously difficult to eliminate without professional help.
Here’s what every pet owner in the Fraser Valley needs to know about fleas, when they’re most active, and how to protect your home and family.
When Does Flea Season Start in BC?
In the Fraser Valley, flea season typically runs from May through October. Fleas thrive when temperatures stay consistently above 12°C with moderate to high humidity — conditions that Maple Ridge and Pitt Meadows experience for about six months of the year.
That said, fleas can survive indoors year-round. If your home is heated and your pets go in and out, a flea problem that starts in summer can easily persist into December. The warmth inside your house gives fleas everything they need to keep reproducing regardless of what’s happening outside.
Peak activity tends to hit in July and August, when temperatures and humidity are at their highest. This is when most Fraser Valley homeowners start noticing bites on their ankles or seeing fleas jump on furniture and bedding.
How Pets Bring Fleas Indoors
Your dog or cat is almost always the entry point. Fleas jump onto pets during walks, backyard time, or contact with other animals. A single adult flea can lay 40 to 50 eggs per day, and those eggs fall off your pet as they move through the house — onto carpets, furniture, pet beds, and between floorboards.
The Flea Lifecycle (Why They’re So Hard to Kill)
Understanding the flea lifecycle explains why a single treatment rarely works:
- Eggs — Laid on the pet, fall into carpets and cracks. Nearly invisible.
- Larvae — Hatch in 2-10 days. Live in carpet fibres and dark areas, feeding on organic debris.
- Pupae — Spin a cocoon and can remain dormant for months, waiting for vibration, warmth, or CO2 (signs of a host nearby). This is the stage that makes fleas so persistent — pupae are nearly impervious to sprays and vacuuming.
- Adults — Jump onto a host, feed on blood, and begin laying eggs within 24-48 hours.
At any given time, only 5% of a flea infestation is adult fleas. The other 95% is eggs, larvae, and pupae hiding throughout your home. This is why killing the adults you can see barely makes a dent.
DIY vs Professional Flea Treatment: What Actually Works
What DIY Can Do
- Vacuuming — This is genuinely helpful. Frequent, thorough vacuuming removes eggs and larvae from carpets and stimulates pupae to hatch (making them vulnerable to treatment). Vacuum daily during an active infestation and dispose of the bag or empty the canister outside immediately.
- Washing pet bedding — Hot water (60°C+) kills all flea life stages. Wash weekly.
- Flea combs — Useful for checking your pet and removing adult fleas, but won’t solve an infestation.
- Over-the-counter sprays and foggers — These can kill adult fleas on contact but rarely reach larvae in carpet fibres or pupae in cocoons. Foggers (“flea bombs”) often push fleas into untreated areas rather than eliminating them.
Where DIY Falls Short
The problem with DIY flea treatment is coverage and persistence. Store-bought products typically can’t reach the places where flea larvae and pupae hide — deep in carpet pile, under furniture, in cracks between hardwood planks, and inside upholstered furniture. And because pupae can remain dormant for months, a single treatment always leaves survivors.
If you’ve been battling fleas for more than two weeks with DIY methods and the problem isn’t improving, it’s time to call a professional.
How Canadian Pest Control Treats Flea Infestations
At Canadian Pest Control, our flea treatment process is designed to break the lifecycle at every stage:
- Inspection — We assess the severity of the infestation, identify hotspots (pet resting areas, carpeted rooms, baseboards), and determine the treatment plan.
- Targeted treatment — We apply professional-grade products that reach larvae and pupae in carpets, cracks, and upholstered surfaces. These products include both knockdown agents for adult fleas and insect growth regulators (IGRs) that prevent eggs and larvae from developing.
- Follow-up — Because pupae can survive initial treatment, we typically recommend a follow-up visit 2-3 weeks later to catch any fleas that have emerged from cocoons since the first treatment.
We use products that are safe for families and pets once dry, and we’ll give you specific instructions on preparation and re-entry timing.
Prevention Tips for Fraser Valley Pet Owners
The best flea treatment is prevention. Here’s how to keep fleas out of your home in the first place:
Keep Your Pets Treated Year-Round
Talk to your vet about a year-round flea preventative — not just during summer. Topical treatments, oral medications, and flea collars all work, but consistency is key. Skipping winter months is a common mistake in the Fraser Valley because our winters are mild enough for fleas to survive outdoors in sheltered spots.
Maintain Your Yard
Fleas thrive in shaded, humid areas of your yard. Keep grass trimmed short, clear leaf litter and debris, and reduce shaded harborage areas near your home’s foundation. If your pets spend a lot of time in the backyard, this simple maintenance significantly reduces flea exposure.
Vacuum Regularly
Even without an active infestation, weekly vacuuming removes flea eggs before they can develop. Pay extra attention to areas where your pets sleep and along baseboards.
Watch for Early Signs
Catch fleas early before they become an infestation. Signs to watch for:
- Your pet scratching more than usual, especially around the neck and base of the tail
- Small dark specks in your pet’s fur (“flea dirt” — actually flea feces)
- Tiny red bites on your ankles and lower legs
- Seeing small jumping insects on furniture or bedding

Don’t Let Fleas Take Over Your Home
Fleas reproduce fast, hide well, and resist casual treatment. The longer you wait, the harder and more expensive the problem becomes. If you’re seeing signs of fleas in your Maple Ridge, Pitt Meadows, Langley, or Fraser Valley home, don’t waste weeks on products that won’t reach the real problem.
