Mosquito season in St. Louis can be brutal, with warm temperatures and high humidity creating the perfect breeding ground for these pesky insects. Not only do mosquitoes cause irritating bites, but they also pose health risks by carrying diseases such as West Nile virus and Zika virus.

The good news? You can take proactive steps to mosquito-proof your home and enjoy your summer bite-free. In this guide, we’ll cover proper screening techniques, yard maintenance tips, and how STL Pest Control’s expert treatments can help keep mosquitoes at bay.


1. Screening Doors and Windows Properly

One of the easiest ways to keep mosquitoes out of your home is by securing all entry points, including doors and windows. Here’s how:

Inspect for Gaps and Tears

Even the smallest hole in a window or door screen can be an open invitation for mosquitoes. Check all screens and replace or repair any damaged sections to keep your home protected.

Use Proper Screen Mesh Size

A fine mesh screen with a 16–18 mesh count is ideal for blocking mosquitoes while still allowing fresh air into your home. Avoid larger mesh sizes that might let tiny mosquitoes slip through.

Install Weather Stripping and Door Sweeps

Even with good screens, mosquitoes can sneak in through gaps under doors or around windows. Weather stripping and door sweeps help seal these small openings.

Consider a Screened-In Porch

Love spending time outside but hate mosquito bites? Screened-in porches offer a comfortable outdoor space where you can relax without worrying about pests.


2. Yard Maintenance Tips for Reducing Mosquito Populations

Since mosquitoes breed outdoors, proper yard maintenance is essential to keep their populations under control.

Eliminate Standing Water

Mosquitoes lay their eggs in standing water, so it’s crucial to remove any potential breeding grounds from your property. Be sure to:

  • Empty birdbaths, plant saucers, and pet bowls at least once a week.

  • Check for clogged gutters that may hold stagnant water.

  • Keep pool covers and tarps dry and free of puddles.

Keep Grass and Shrubs Trimmed

Mosquitoes rest in shady, damp areas, such as tall grass and overgrown bushes. By keeping your lawn mowed and trimming shrubs, you reduce hiding spots for these pests.

Use Mosquito-Repelling Plants

Certain plants naturally repel mosquitoes, including:

  • Citronella

  • Lavender

  • Marigolds

  • Basil

Plant these around patios, walkways, and outdoor sitting areas to help deter mosquitoes naturally.

Encourage Natural Predators

Mosquitoes have several natural predators, such as:

  • Birds

  • Dragonflies

  • Bats

Setting up birdhouses or bat boxes can encourage these helpful creatures to stick around and reduce the mosquito population in your yard.


3. How STL Pest Control’s Treatments Create a Mosquito-Free Zone
