Why Sprays and Zappers Fall Short

Citronella candles, bug zappers, and chemical sprays are the go-to mosquito solutions for most homeowners. But they all share the same weakness: they reduce mosquitoes without eliminating them. One bite is all it takes to ruin an evening outdoors.

Chemical sprays also carry health concerns — especially for children, pets, and anyone sensitive to DEET or permethrin. And they need constant reapplication.

The Screen Enclosure Advantage

A physical barrier is designed to keep mosquitoes out rather than just reduce them. Retractable screens are designed to close off an outdoor room with insect mesh, keeping airflow and visibility while screening out bugs.

Unlike permanent screen rooms, retractable systems let you open up completely on bug-free days. Motorized operation means switching between open and enclosed in under 30 seconds.

Best Applications

Retractable screens work on virtually any outdoor structure:

Patios — wall-mount to the house and post supports for a flush seal
Decks — mount to railing posts or overhead beams
Gazebos — enclose all four sides with independently controlled screens
Porches — convert a three-season porch into a screened room

Mesh Options

Not all screen mesh is the same. For mosquito control specifically, you need a mesh density of at least 18x14 (18 horizontal threads per inch, 14 vertical). Ask for the mesh count of any insect screen you're quoted.

For areas with black flies or no-see-ums, we offer finer mesh options. There's a slight trade-off in airflow, but it's often worth it for lakefront and rural properties.

Cost vs. Chemical Treatments

Professional mosquito spraying is a recurring seasonal cost and needs regular reapplication, with ongoing chemical exposure.

A retractable screen system is a one-time purchase, covered by the manufacturer's warranty. When closed, it screens insects out of the enclosed area and makes the space more usable through bug season.

Common Questions

Mosquito Screen FAQ

Can retractable screens help with mosquitoes on a patio?

Yes, retractable screens provide insect screening without sprays or candles. When lowered, insect mesh closes the opening, side tracks hold the fabric edges in a closed channel, and a weighted bottom bar sits at the base. Those details matter as much as the fabric, and every open side needs its own screen. Raise the screens when you want open air back. Learn more about our retractable privacy screens.

What screen mesh size is used for mosquitoes?

Insect screens for mosquitoes are commonly specified at a mesh count of about 18x14, meaning 18 threads per inch one way and 14 the other. Finer mesh is available for smaller insects such as black flies and no-see-ums, which can matter on lakefront and rural properties, with a slight trade-off in airflow. Ask any installer for the mesh count of the insect screen they are quoting.

Retractable screens or mosquito spraying: what's the difference?

Spraying reduces mosquitoes for a period and needs regular reapplication, which makes it a recurring seasonal cost with ongoing chemical exposure. A retractable screen is a one-time purchase that physically screens the opening with insect mesh whenever it is lowered, but it only covers the enclosed area, not the rest of the yard. The product carries the manufacturer's warranty, and Canada Shutter Pros adds a 1-year labour and installation warranty.

Can you add mosquito screens to a gazebo or deck?

Yes. Retractable screens can mount to gazebo posts and beams, to deck railing posts or overhead beams, or to the house wall and post supports on a patio. A gazebo can be enclosed on every side with independently controlled screens, and a three-season porch can become a screened room. Mounting details are confirmed during a free onsite visit. See our gazebo screens for examples.

Can one screen provide both privacy and insect screening?

It can, depending on the fabric. Screen fabrics are designed for several jobs at once, including insect control, shade, ventilation and privacy. A denser mesh, such as a 5% openness fabric, adds daytime privacy along with insect screening, while an open insect mesh keeps more view and airflow but offers essentially no privacy. Our guide to privacy screens at night compares the fabric options.
