When Does Mosquito Season Start in Virginia Beach?

If you live in Virginia Beach or anywhere in Hampton Roads, you already know mosquitoes are part of the deal. What catches most people off guard is how early they show up and how long they stick around. Mosquito season here is not a two-month summer problem. In most years, it stretches from April through October, and warmer years push it even longer.

At Precision Pest Management, we start getting calls about mosquitoes in late March and early April, right as temperatures climb and spring rains fill every low spot, gutter, and drainage ditch across the region. By mid-May, populations are fully established. By July, they are at their worst. Homeowners who wait until they are getting bitten to think about mosquito control are already behind.

Here is a practical, month-by-month look at what to expect so you can plan ahead and actually enjoy your outdoor space this year.

Month-by-Month Mosquito Activity in Hampton Roads

January and February: Mosquitoes are dormant or inactive. Temperatures are too low for breeding or significant activity. This is the best time to address standing water sources, clean gutters, and fix drainage issues before the season begins.

March: As temperatures start reaching the mid-50s consistently, overwintering mosquito eggs begin hatching. You will not notice much biting activity yet, but the cycle is starting underground and in standing water. Early-season preparation pays off here.

April: This is when mosquito season officially begins in Hampton Roads. Daytime temperatures in the 60s and 70s combined with spring rain create ideal breeding conditions. The Asian tiger mosquito, the most common and aggressive daytime biter in our area, starts showing up in yards. This is when we recommend starting professional treatments if you plan to use a seasonal service.

May: Populations ramp up fast. A single female mosquito can lay 100 to 200 eggs at a time, and in May's warm conditions those eggs develop into biting adults in about a week. If you have standing water on your property that has not been addressed, this is when it starts producing mosquitoes at volume.

June: Full mosquito season. Activity is high throughout the day, especially in shaded areas and near vegetation. Evening outdoor activities become noticeably uncomfortable without some form of protection in place. Barrier treatments applied monthly are keeping populations suppressed for our customers by this point.

July and August: Peak season. This is when mosquito pressure in Hampton Roads is at its most intense. High temperatures, sustained humidity, and accumulated breeding from the spring months all converge. These are the months when mosquito-borne illness risk is also highest, including West Nile virus and Eastern equine encephalitis, both of which are reported in Virginia.

September: Mosquito activity remains high through most of September, especially during warm stretches. Many homeowners make the mistake of dropping their guard or skipping treatments because summer is over. In Hampton Roads, September mosquitoes can be just as aggressive as July mosquitoes.

October: Activity begins declining as nighttime temperatures drop into the 50s and below. Depending on the year, you may still see significant biting through mid-October. Late-season treatments ensure populations do not surge during warm spells.

November and December: Mosquitoes become dormant as temperatures fall. Adult mosquitoes die off or seek sheltered overwintering spots. Eggs laid in fall can survive the winter and hatch the following spring, which is why eliminating standing water in fall matters for next year's season.

What Drives Mosquito Season in Hampton Roads

Mosquito populations in Virginia Beach are not random. Three factors drive the timing and intensity of every season.

Temperature is the primary trigger. Mosquitoes become active around 50 degrees Fahrenheit and breed most efficiently between 70 and 85 degrees. Hampton Roads hits that sweet spot earlier in spring and holds it later into fall than most of the Mid-Atlantic, which is why our season is longer than what you would experience even an hour or two inland.

Standing water is where they reproduce. Every mosquito you swat started as an egg laid in standing water. It does not take much. A bottle cap, a folded tarp, the corrugated downspout extensions found on homes throughout Norfolk and Portsmouth, a plant saucer, a clogged gutter. The Asian tiger mosquito in particular thrives in small containers of water close to homes, which means the mosquitoes biting you are almost always breeding somewhere on or very near your property.

Common breeding sites on Hampton Roads properties include:

• Clogged or slow-draining gutters
• Bird baths that are not refreshed weekly
• Plant saucers and flower pot trays
• Old tires, buckets, wheelbarrows, and kids toys that hold water
• Tarps and pool covers with collected rainwater
• Low spots in the yard that puddle after rain
• Corrugated downspout extensions and drainage features

Storms accelerate everything. Hampton Roads sits in a hurricane and tropical storm corridor. After major rain events, standing water spreads across neighborhoods on a massive scale, and mosquito populations can explode within a week. Post-storm surges are some of the worst mosquito events of the year, and they can extend the active season well past its normal October wind-down.

Why Virginia Beach Mosquitoes Are Worse Than Most Places

Hampton Roads is not just another Mid-Atlantic metro when it comes to mosquitoes. Several factors specific to our geography make the problem more persistent here.

Tidal wetlands and coastal proximity. The marshlands along the Lynnhaven Inlet, the tributaries feeding into the Chesapeake Bay, and the Great Dismal Swamp to the southwest all provide large-scale mosquito breeding habitat that feeds populations across the region.

Dense residential neighborhoods. Homes close together mean more combined standing water sources within the flight range of a single mosquito. The Asian tiger mosquito typically stays within 200 to 300 yards of where it emerged, so your neighbor's clogged gutter can absolutely be producing the mosquitoes that are biting you.

Military installations and travel hubs. The movement of people and goods through Norfolk Naval Station, Joint Expeditionary Base Little Creek, Langley, and other installations means new mosquito species and disease vectors can be introduced to the region more easily than in less connected areas.

Mild winters. Hampton Roads winters rarely sustain temperatures cold enough to kill off mosquito eggs completely. Overwintering eggs survive in leaf litter, soil, and containers and are ready to hatch at the first sustained warm spell in spring.

How PPM Keeps Your Yard Comfortable All Season

At Precision Pest Management, our mosquito control program is built around the way mosquitoes actually behave in Hampton Roads, not around a generic national playbook.

We start with your property, not just a spray. Every service begins with an assessment of your yard's specific breeding sites and harborage zones. We flag standing water sources and make specific recommendations for each one, because eliminating breeding habitat is the single most effective thing you can do to reduce mosquito populations on your property.

Barrier treatments target where mosquitoes rest. We apply ultra-low volume treatments to the vegetation, shaded areas, fence lines, under decks, and garden beds where adult mosquitoes spend most of their day. A single barrier treatment typically reduces adult mosquito populations by 70 to 90 percent for two to three weeks.

Larvicide treatments stop them before they bite. For standing water sources that cannot be drained, like retention ponds, ornamental water features, and storm drainage, we apply targeted larvicide treatments using Bti (Bacillus thuringiensis israelensis). Bti is a naturally occurring bacterium that stops larvae from developing into adults and is safe for fish, birds, pets, and beneficial insects.

Monthly service through the full season. We recommend starting treatments in April and continuing monthly through October. That cadence keeps populations suppressed through every phase of the season, including the late-summer peak and the September surge that surprises homeowners who stop too early.

Our Premium Protection plan includes monthly mosquito control built into the service, alongside residential pest control and termite control. For homeowners who want mosquito service as a standalone, we offer seasonal mosquito plans as well.

If mosquitoes come back between treatments, so do we, at no additional charge. That is our satisfaction guarantee.

What You Can Do Before the Season Starts

Professional treatment works best when paired with a few practical steps on your end. Here is what we tell every homeowner before mosquito season kicks in.

Walk your property and eliminate standing water. Do this in March, before mosquitoes start breeding. Dump anything holding water. Fix gutters. Level low spots. Refresh bird baths weekly. This step alone removes more mosquitoes than any spray can.

Trim vegetation and clear leaf litter. Mosquitoes rest in dense, shaded vegetation during the hottest parts of the day. Trimming shrubs, mowing regularly, and clearing leaf litter from fence lines and garden beds reduces harborage and makes your barrier treatments more effective.

Check your screens. Make sure window and door screens are intact and fit tightly. The Asian tiger mosquito is small enough to get through damaged screens, and one mosquito indoors can ruin a night.

Schedule your first treatment in April. If you are planning to use professional mosquito control this year, do not wait until June. Early-season treatments disrupt breeding before populations build, and that head start carries through the whole season.
