Why mosquito season hits harder here.

Mosquitoes need standing water to breed and humidity to thrive, and the Tidewater region — Hampton Roads, the Chesapeake Bay shoreline, and everywhere in between — has both in abundance. Compared to Richmond, Northern Virginia, or the Shenandoah Valley, this region simply gives mosquitoes more of what they need for a longer stretch of the year.

What makes this region different

• Coastal humidity keeps conditions favorable for mosquito activity later into the evening and later into the season than drier inland areas
• Tidal and marsh areas throughout the region create natural standing water sources that don't exist the same way further inland
• Waterfront neighborhoods — common throughout Norfolk, Portsmouth, Suffolk, and Virginia Beach — sit closer to breeding sources than most inland Virginia housing

Why yard treatment matters more than most people think

Adult mosquitoes rest in shaded vegetation during the day and only need a small amount of standing water to breed — sometimes as little as what collects in a clogged gutter or a forgotten planter. Fogging kills what's flying at the moment but does nothing about the resting population or the breeding sites that will simply replace them within days.

What actually works in this climate

• Eliminating standing water around the property — the single highest-impact thing a homeowner can do themselves
• Barrier treatment on shaded vegetation and resting areas, not just open-air spraying
• A recurring seasonal schedule, typically April through October in this region, since rainfall washes out single treatments within a few weeks
• Extra attention near water-adjacent properties, which generally need more frequent treatment than inland properties on the same plan

Because the season runs longer here than in most of Virginia, timing a treatment plan to start early in spring — rather than reacting once mosquitoes are already a problem — tends to make a bigger difference in this region than almost anywhere else in the state.
