Homeowners and renters in Chesapeake who want their yard back.
What to look for
Often the source is a neighbor's yard or a storm drain. Mosquitoes breed in standing water, even a bottle cap's worth. In summer heat, eggs become biting adults in about a week.
- 1Standing water in low spots a week after rain.
- 2Ornamental pond with no fish or pump.
- 3Dogs testing positive for heartworm.
- 4Welts on ankles and calves after yardwork.
- 5Whining near your ears at night indoors.
- 6Egg rafts floating on stagnant water.
Why it’s worth acting soon
- Each new generation is bigger than the last.
- Bites can spread West Nile virus.
- Itchy welts, especially for kids.
- Heartworm risk for dogs.

Adult mosquitoes spend the day in shady, leafy beds like this one, so that's where a barrier treatment goes.How mosquito treatment works in Chesapeake.
First, find and remove the water where they breed. Then spray where the adults rest. Across Chesapeake, the season runs from about May through September, so a plan usually starts in spring and runs to the end of the season. Larvicide handles water you can't drain, like ponds or drains. Barrier spray covers shady shrubs and leaves. Treatment has two parts.
Which mosquitoes bite around Chesapeake.
Near the coast, salt-marsh mosquitoes can fly into Chesapeake from miles away. Asian tiger mosquitoes are common around Chesapeake. They're black-and-white and bite by day. They breed in small containers. House mosquitoes (Culex) bite from dusk into the night. They breed in storm drains. They're the main West Nile carriers.
Mosquitoes that bite indoors usually slip in through gaps around doors or torn window screens.Mosquito season in Chesapeake.
Numbers usually peak in July and August. West Nile cases usually peak in late summer.
A year of mosquitoes in Chesapeake.
- Spring: dump water and clean gutters before May. - Summer: peak season in Chesapeake, especially July and August. - Fall: activity fades with cooler nights. - Winter: fix drainage and store containers upside down.
The weekly water walk.
- Saucers and pots: empty them or add sand. - Toys and buckets: store them upside down. - Tarps and covers: pull them tight so water runs off. - Birdbaths: change the water twice a week. - Pet bowls: refresh daily. - AC drip lines and downspouts: make sure water drains away. - Tree holes: fill them with sand. - Gutters: clear leaves so water drains.
Avoiding bites.
- Clothing: long sleeves and pants help at dusk. - Fans: a patio fan keeps weak-flying mosquitoes away. - Screens: repair holes in window and door screens. - Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus.
Low-cost ways to cut mosquitoes.
- Mosquito fish: they eat larvae in ornamental ponds. - Pumps and fountains: moving water breeds far fewer mosquitoes. - Trimming: thin out dense shrubs and tall grass. - Lights: yellow bug lights attract fewer insects to the porch. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds.
Mosquito or look-alike?
- Non-biting midges: swarm near water at dusk. Harmless, just annoying. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh. - Mosquitoes: slim, long legs, and a needle-like mouth. - Crane flies: look like giant mosquitoes. They don’t bite.
When a bite needs a doctor.
Most people infected with West Nile virus never feel sick. About one in five get a fever, headache or body aches. See a doctor for high fever, stiff neck or confusion. Spreading swelling or an infected-looking bite needs a check too. Most bites just itch for a few days.
Protecting your pets.
Heartworm reaches dogs through mosquito bites, and cats can get it as well; Chesapeake's June–October season is long enough that most vets advise year-round prevention. Talk to your vet about year-round prevention. Refresh pet water bowls daily; with about 48 inches of rain a year in Chesapeake, bowls and plant saucers refill themselves. Keep animals inside until a yard treatment dries.
What a treatment visit looks like.
Then they spray shady shrubs, where adults rest. Most plans repeat every three to four weeks. A visit usually takes 20 to 45 minutes. The tech walks the yard first. They dump or treat standing water. Larvicide goes in water you can't drain.
Rain barrels and ponds.
- Ponds: fish and moving water keep larvae down. - Bird baths: change the water every few days. - Gutters: clear them so water drains away. - Tarps: shake out any that hold rainwater. - Pool covers: drain standing water after rain. - Barrels: cover openings with fine mesh.
