How to get rid of mosquitoes in Marietta yards

Warm evenings, late-day storms, and mature tree canopy around Marietta Square, East Cobb, Sope Creek, Kennesaw Mountain, and Whitlock Heights create perfect conditions for mosquitoes. This post highlights the seven yard habits that keep bites coming back — plus quick fixes that actually work. If you’re ready for a season-long plan, see our mosquito control in Marietta page.

1) Irrigation Overspray That Mists Walls & Patios

• 1
  Why it’s a problem: Overspray keeps surfaces damp along the home’s perimeter/foundation, creating shaded, humid resting zones where adult mosquitoes linger.
• 2
  Fix: Re-aim heads so they don’t mist walls or hardscape, shorten run times in shaded beds, and water early mornings so surfaces dry quickly.

2) Mulch Mounded Against Exterior Materials

• 1
  Why it’s a problem: When mulch is piled against brick ledges or touches exterior siding, it traps moisture. After rain or irrigation, water lingers and small damp pockets form—creating ideal conditions for pests and moisture-related damage to exterior materials.
• 2
  Fix: Maintain a 6 inch clearance between mulch and any exterior surface. In areas that stay damp, replace the mulch directly against the foundation with a narrow strip of stone or gravel to improve drainage and drying.

3) Ignoring “Small Containers”

• 1
  Why it’s a problem: Items like plant saucers, buckets, toys, tarps, clogged gutters, or even bottle caps can collect water. These small, overlooked containers can hold enough water for pests to breed, especially after rain.
• 2
  Fix: Do a weekly sweep of the yard and outdoor areas. Empty, flip over, or remove any items that can collect water. Drill drainage holes in planters and routinely clear gutters and low spots where water tends to pool.

4) Missing Gutter & Downspout Problems

• 1
  Why it’s a problem: Clogged gutters and short downspouts hold water and feed low-spot puddles near the house.
• 2
  Fix: Clear gutters after storms and add splash blocks/extensions so water moves away from the home’s perimeter/foundation.

5) Letting Vegetation Hug the House

• 1
  Why it’s a problem: Dense hedges create cool, humid resting zones on leaf undersides—prime spots for adults.
• 2
  Fix: Trim shrubs 12–18 inches off exterior walls; raise canopies for airflow and quicker dry-out.

6) Overlooking Low Spots in the Lawn

• 1
  Why it’s a problem: Shallow depressions can hold puddles for days after rain or irrigation.
• 2
  Fix: Fill and re-sod low spots; add a small drainage cut or channel where patios hold water against the house.

7) Treating Everywhere, Instead of Where It Works

• 1
  Why it’s a problem: Broad, unnecessary spraying wastes time and materials while often missing the true hotspots where pests rest and breed. This approach can reduce effectiveness and lead to recurring activity.
• 2
  Fix: Focus treatments on key resting areas (such as shaded vegetation) and specific breeding sites. Pair targeted applications with consistent yard practices—like moisture control and routine inspections—for longer-lasting, more reliable results.
