Two mosquito species dominate Hampton Roads: the Asian Tiger Mosquito, an aggressive daytime biter that breeds in containers, and the Southern House Mosquito, the primary evening biter and carrier of West Nile Virus in Virginia.
Identification
How to Identify Mosquitoes in Hampton Roads
The Asian Tiger Mosquito (Aedes albopictus) is the most visible daytime biter in Hampton Roads. It is small — roughly 2 to 10 mm — with a distinctive black and white striped pattern on its body and legs. Its single white stripe running down the center of the thorax is the easiest field identification mark.
The Southern House Mosquito (Culex quinquefasciatus) is the primary nighttime biter and is the species most associated with West Nile Virus transmission in Virginia. It is a medium-sized, brown mosquito with banded legs and a blunt abdomen tip. It is most active from dusk until midnight.
Both species produce a characteristic high-pitched whine from wing beats. Female mosquitoes — the ones that bite — have a long, needle-like proboscis. Males have bushy, feathery antennae and do not bite.
Behavior & Diet
Behavior and Breeding Habits
Female mosquitoes require a blood meal to produce eggs. They locate hosts using a combination of carbon dioxide exhaled during breathing, body heat, and certain body odors. A single female can lay up to 300 eggs per batch and produce multiple batches in her lifetime.
Asian Tiger Mosquitoes breed in any container holding as little as a teaspoon of standing water. Clogged gutters, bird baths, plant saucers, children's toys, and tarps are the most common breeding sites in Virginia Beach and Hampton Roads yards. They rarely travel more than a few hundred feet from where they hatched.
Southern House Mosquitoes prefer larger, organically rich standing water — drainage ditches, storm water ponds, swampy areas, and clogged storm drains. They can travel up to a mile from breeding sites. Hampton Roads geography, with its tidal waterways, drainage infrastructure, and high rainfall, provides ideal conditions.
Threats & Damage
Health Risks in Hampton Roads
Mosquitoes are the deadliest animal genus on Earth by human mortality. In Hampton Roads, the primary disease risks are West Nile Virus, transmitted by Culex species, and Eastern Equine Encephalitis (EEE), a rare but high-fatality virus confirmed periodically in Virginia.
The Virginia Department of Health monitors mosquito-borne disease activity across Hampton Roads and issues public alerts when positive West Nile detections are confirmed in mosquito pools or dead birds in a region.
For pets, mosquitoes transmit heartworm. A single bite from an infected mosquito is enough to transmit Dirofilaria immitis larvae. Heartworm infection without treatment is fatal in dogs and can affect cats as well.
Prevention & Treatment
Prevention and Treatment
Elimination of standing water is the most effective source reduction strategy. Walk your property after every rain and tip out or cover any container holding water. Clean gutters at least twice yearly — in Hampton Roads, leaf and debris accumulation in gutters is the single biggest residential mosquito breeding site.
Professional barrier spray treatments apply residual insecticide to all vegetation on your property — shrubs, ground cover, fences, and tree lines — where adult mosquitoes rest during daylight hours. A single treatment remains effective for 21 to 28 days. Monthly treatments from April through October maintain active protection.
For standing water that cannot be drained — catch basins, ornamental ponds, or permanent drainage features — we use BTi (Bacillus thuringiensis israelensis), a naturally occurring bacteria that kills mosquito larvae without harming fish, pet, or beneficial insects.
