Mosquitoes in Brunswick, New Hanover, Pender & Surrounding Counties: What Homeowners Need to Know.

If you live in southeastern North Carolina—especially in Brunswick, New Hanover, or Pender County—you already know mosquitoes are not just a summer nuisance. Thanks to our coastal climate, marshlands, and frequent rainfall, mosquito activity can last most of the year.

Understanding the most common mosquito species in our area—and how to control them—can make a big difference in protecting your home, yard, and family.

Most Common Mosquitoes in southeastern North Carolina:

• Asian Tiger Mosquito (Aedes albopictus)

  One of the most aggressive and common mosquitoes in residential neighborhoods.

  • When they bite: Daytime (morning & late afternoon)

  • Where they breed: Small containers (gutters, flower pots, birdbaths)

  • Health concerns: Can transmit Zika virus, Dengue fever, and Chikungunya

• Southern House Mosquito (Culex quinquefasciatus)

  A major issue in urban and suburban areas like Wilmington and Leland.

  • When they bite: Evening and nighttime

  • Where they breed: Storm drains, ditches, and stagnant water

  • Health concerns: Known carrier of West Nile virus and Eastern equine encephalitis

• Eastern Saltmarsh Mosquito (Aedes sollicitans)

  A major problem in coastal Brunswick County and areas near marshes and the Intracoastal Waterway.

  • When they bite: Day and night (very aggressive)

  • Where they breed: Salt marshes and tidal flooding areas

  • Why they’re a problem: Can travel miles inland, affecting entire neighborhoods

• Inland Floodwater Mosquito (Aedes vexans)

  Common after heavy rains and storms across all three counties.

  • When they bite: Evening and night

  • Where they breed: Temporary standing water (puddles, low spots, fields)

  • Why they’re a problem: Populations explode quickly after rain events

    
    

Reducing the mosquito population around your property:

In coastal North Carolina, mosquito control requires more than just occasional spraying. Long-term prevention is key.

• Eliminate Standing Water

Mosquitoes can breed in as little as a bottle cap of water. Focus on clearing out gutters and downspouts, flower pots and planets and refresh birdbaths weekly.

• Maintain Your Yard

  Be sure to keep grass trimmed, reduce dense shrubs and shaded area and improve drainage in low spots.

• Consider Long-Term Mosquito Control Solutions

Homeowners across Brunswick, New Hanover, and Pender counties are increasingly choosing:

• Mosquito trapping systems for continuous population reduction.

• Targeted larval treatments in problem areas.

• Barrier treatments for immediate relief when needed.

Mosquito Season in Southeastern NC

In our area, mosquito activity typically starts in early spring (March-April), peaks during the summer months (May-September) and continues into the fall (October & November) due to the mild temperatures and continued storms.

Mosquitoes are a fact of life in Brunswick, New Hanover, and Pender counties—but they don’t have to take over your yard. By understanding which species you’re dealing with and focusing on long-term prevention strategies, you can significantly reduce their impact.

Whether you’re dealing with daytime biters in Wilmington, saltmarsh swarms near the coast, or post-storm outbreaks inland, the key is consistent control and eliminating breeding sites.
