The Tier System — Ranked by Evidence
🟢 Tier 1: Gold Standard (Health Canada-approved, peer-reviewed)
- DEET (20–30%) — 6–10 hours of protection. The most-studied repellent in history. Brands: Off Deep Woods, Watkins.
- Picaridin (20%) — 6–10 hours, no plastic/fabric damage, odourless. Brands: Sawyer, Natrapel.
- IR3535 (15–20%) — 4–8 hours. Less common in Canadian retail but evidence-backed.
🟡 Tier 2: Effective natural options
- Oil of Lemon Eucalyptus (OLE / PMD, 30%) — 4–6 hours. The only natural option with DEET-comparable evidence. Brands: Off Botanicals, Repel Lemon Eucalyptus.
- 2-Undecanone (BioUD) — Comparable to OLE, less common in Canadian retail.
🟠 Tier 3: Real but short-duration
- Citronella oil sprays — 30–60 minutes.
- Soybean oil products (Bite Blocker) — ~1.5 hours.
- Geraniol — 1–2 hours.
🔴 Tier 4: Marketing more than mosquitoes (avoid)
- Ultrasonic devices — Studies confirm: zero effect.
- Bracelets and wristbands — Protects only the wrist.
- Generic essential oil blends — 15–60 minutes weak repellency.
- Bug zappers — Kill mostly beneficial insects, not biting mosquitoes. (CO2 traps are the one trap category with real evidence behind it — see our Mosquito Magnet review.)
- Mosquito-repelling plant beds — Tiny effect; oils only release when leaves are crushed.
What to Buy for What Situation
- Backyard BBQ (2–3 hours): 20% picaridin spray.
- Long hike or camping: 30% DEET or 20% picaridin.
- Kids 2–12 years: 10% DEET or 20% picaridin (one application per day max for under 2).
- Babies under 6 months: No chemical repellent. Use mosquito netting + long sleeves.
- Pregnant women: Picaridin or DEET both Health Canada-approved during pregnancy.
- Pets in yard: Don’t apply human repellents to pets. Use vet-prescribed flea/tick preventatives + professional yard barrier spray.
The Strategy Most Ontario Homeowners Miss
Personal repellent is for outdoor activities away from your property. For your own backyard, a much better strategy is professional barrier spray — applied to vegetation perimeters and shrub interiors where mosquitoes rest. This controls the population in your yard for 21–30 days at a time, so you don’t need to apply repellent every time you step outside.
Most homeowners think the choice is between DIY repellent or nothing. The third option — and usually the best one — is professional yard treatment so personal repellent becomes unnecessary at home. That is the model we run across the GTA from our Mississauga base: the same May-to-September programs behind our mosquito control in Toronto and Mississauga mosquito spraying.
Cost Comparison (per Ontario season)
- DIY personal repellent only: $30–$60/season for sprays + reapplications
- BTI Mosquito Dunks (water source treatment): $15/season
- BuzzSkito Basic seasonal (5 sprays): $549
- BuzzSkito Standard seasonal (10 sprays): $994
For most Ontario yards, the Standard plan delivers a continuously bug-free yard from May through September. The cost works out to ~$100/month for full-yard control — comparable to monthly grocery spend on patio dinners that are now actually enjoyable. Season pricing scales with lot size, so if you are comparing a bottle of repellent against a full program, start with what mosquito control costs in Ontario by property size.
What to Skip
- Ultrasonic plug-ins or yard devices (zero evidence)
- Mosquito-repelling bracelets/wristbands
- Citronella tiki torches (1-metre downwind effect only)
- Bug zappers (kill the wrong insects)
- “DIY essential oil” sprays from Pinterest (most don’t work)
