Mosquito netting and barrier spray are both real solutions to mosquito problems — but they solve different problems. Netting protects an enclosed space; barrier spray protects an entire yard. Here’s how to decide which one (or both) fits your situation.
The Quick Comparison
| Factor | Mosquito Netting | Barrier Spray |
|---|---|---|
| Coverage | Enclosed area only | Entire yard |
| Effectiveness inside | 100% bug-free | 90%+ population reduction |
| Effectiveness outside the zone | 0% (not protected) | 90%+ population reduction |
| Initial cost | $200–$15,000 (depending on scope) | $0 |
| Annual cost | $0 (after purchase) | $549–$2,049 |
| Setup | Permanent or seasonal install | None — we come to you |
| Aesthetic impact | Visible structure / mesh | Invisible |
| Movement freedom | Confined to enclosure | Use entire yard |
| Best for | Defined dining/lounging zone | Whole-yard use (kids, pets, gardening) |
When Mosquito Netting Wins
- You only need one bug-free spot. A single screened patio or porch is all you need; the rest of the yard isn’t actively used.
- Renting / can’t modify the property permanently. A freestanding $400 gazebo packs up at season end.
- Camping or cottage use. Portable mosquito netting tents protect a campsite without needing yard treatment.
- Babies under 6 months. Stroller/crib netting is the only mosquito protection Health Canada recommends for infants.
- You want zero pesticide exposure. Netting is purely physical — no chemistry involved.
When Barrier Spray Wins
- You actually use your entire backyard. Kids playing on the lawn, dogs running, gardening, BBQ near the trees, lawn games — netting confines you to one spot.
- You have moderate-to-high mosquito pressure. Ravine-adjacent, creek-adjacent, conservation-adjacent properties have so many mosquitoes that a single screened area still means an unusable rest of yard.
- You don’t want to set up and tear down a structure. Spray is invisible and continuous.
- Your yard has features that don’t fit under a gazebo. Pool, large patio, mature trees, garden beds — these can’t be enclosed easily.
- You also have ticks. Netting does nothing for ticks (ticks live on grass, not in the air). Barrier spray controls both.
The Combination That Works for Most Ontario Homeowners
For Ontario yards under significant mosquito pressure (ravine-adjacent, near a creek or marsh, or just generally heavy in May–July), the most-comfortable setup is:
- Barrier spray for the whole yard. Population reduction across all the lawn, garden, and play areas. Standard plan = continuous coverage May–September.
- A screened gazebo or pergola for evening dining. 100% bug-free zone for dinner, conversations, evening drinks.
- Mosquito netting for sleeping areas in cottages or camping. Portable, zero pesticide.
This costs around $1,000–$2,000 in year one (gazebo + first season of spray) and $549–$994/year after.
The Real Cost of Doing Nothing
The most common Ontario homeowner choice is “put up with it” — citronella candles on the patio, swatting between bites, cutting outdoor time short. The hidden cost: you stop using your backyard. A 1,500 sq ft yard you don’t use is the most expensive square footage on your property.
If you’re reading this guide, you’re past the “put up with it” phase. The honest question is whether netting (defined zone protection) or spray (whole-yard protection) fits your specific outdoor lifestyle.
