Edmonton Mosquitoes 2026: How to Protect Your Home, Yard and Family

Edmonton Homeowner Guide

If it feels like you can't sit on your deck this summer, you're not imagining it. Edmonton is dealing with its worst mosquito season in roughly four decades — and most of the fight is won or lost in your own yard. Here's a practical, no-panic guide for Edmonton homeowners.

What's actually happening

City monitoring has found roughly 15 times more mosquitoes than at the same point last year — the highest levels Edmonton has seen since the early 1980s. Traps that were catching fewer than 4,000 mosquitoes each at the end of June were averaging more than 13,000 per trap by mid-July. Earlier in the season the jump was just as stark: traps caught 5 mosquitoes on May 23, and 534 by June 20.

The cause is simple: record rainfall. Mosquitoes lay eggs in standing water, and this year gave them an enormous amount of it. Demand for repellent has been heavy enough that some local outdoor retailers have struggled to keep bug spray in stock.

Start in your own yard: remove the water

This is the highest-impact thing you can do, and it costs nothing. Mosquitoes can breed in a surprisingly small amount of standing water — a bottle cap's worth is enough for some species. Walk your property once a week and empty, drain or refresh:

• Clogged eavestroughs — the most-missed breeding site on most Edmonton homes. Clear the debris so they actually drain.
• Plant pot saucers and planters — dump them out after every rain.
• Birdbaths and pet bowls — refresh at least weekly.
• Kiddie pools, wheelbarrows, buckets, garbage bin lids, old tires — turn them over when not in use.
• Sagging tarps and pool or BBQ covers — tighten them so water can't pool.
• Rain barrels — keep them screened and sealed.
• Low spots and ruts in the lawn — fill or regrade so water doesn't sit for days.

A useful rule: if water sits in one place for more than about a week, it can produce mosquitoes. Weekly is the cadence that breaks the cycle.

Choosing a repellent (and using it safely)

DEET is generally the most effective and longest-lasting option. Health guidance is to use it sparingly and only on exposed skin — not under clothing, and not on cuts or irritated skin.

For children, the Public Health Agency of Canada's guidance is more specific:

• Under 6 months: no insect repellent. Protect babies with mosquito netting over the stroller, playpen or carrier instead.
• 6 months to 12 years: icaridin is the preferred repellent. If using DEET in this age range, concentrations around 10% are considered appropriate.
• 6 months to 2 years: no more than one application per day.
• Over 2 years: up to three applications per day.

Two practical notes: apply sunscreen first, then repellent (never a combined product, since sunscreen needs reapplying far more often), and always follow the directions on the product label — they take precedence over any general advice, including this article.

Timing, clothing and your outdoor space

• Dawn and dusk are peak feeding times. If you can shift your yard time toward midday, you'll get bitten far less.
• Cover up: loose, light-coloured long sleeves and pants. Loose matters — mosquitoes can bite through fabric pulled tight against skin.
• Move the air. An outdoor fan on your deck or patio is genuinely effective; mosquitoes are weak fliers and avoid moving air.
• Fix your screens. Check door and window screens for tears and gaps — a cheap repair that pays off all season.
• Trim tall grass and dense shrubs where adult mosquitoes rest during the heat of the day.

The City of Edmonton runs a mosquito control program and publishes current activity levels, so you can check conditions before planning an evening outdoors.

A quick word on health

Most mosquito bites in our area are an itchy nuisance, nothing more. West Nile virus does exist in Alberta, though the risk here is considered low — the same precautions above are what public health recommends to reduce it. If you develop symptoms that concern you after being bitten, talk to a health professional or call Health Link at 811. This article is general information, not medical advice.

Why a REALTOR® is writing about mosquitoes

Because most of this list is home maintenance. Clean eavestroughs, proper drainage, intact screens and a yard that sheds water instead of holding it — those protect your comfort this month, and they protect your property value long term. Standing water and poor grading are the same issues that turn into basement moisture problems and show up on home inspections.

If you'd like a straight answer about how your home is holding up — or what it's worth in today's market — that's exactly what we do. No pressure, no hype, just the numbers and an honest opinion.
