What to look for
In summer heat, eggs become biting adults in about a week. Often the source is a neighbor's yard or a storm drain. Mosquitoes breed in standing water, even a bottle cap's worth.

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 Roanoke.
For Roanoke homes, 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. First, find and remove the water where they breed. Then spray where the adults rest.

A year of mosquitoes in Roanoke.
- Summer: peak season in Roanoke, especially July and August. - Fall: activity fades with cooler nights. - Winter: fix drainage and store containers upside down. - Spring: dump water and clean gutters before May.

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.

Protecting your pets.
Ask your vet about year-round heartworm prevention. Change pet water bowls daily. Keep pets inside while a yard spray dries. Dogs get heartworm from mosquito bites. Cats can too.

Larvicide goes in water you can't drain. 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.
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.
Questions to ask before you sign.

Questions people ask
When should mosquito treatments start each year?

How do I choose a mosquito control company?
Check that they're licensed in Virginia. Ask what products they use and how often they visit. Ask what happens if bites come back.
Will mosquito treatment kill bees and butterflies?
It can if spray hits flowers. Ask them to skip blooming plants. Spraying when bees rest helps too.

For a few homes, yes. They're costly to install and need refills. Most yards do fine with source removal and regular spraying.
Why are there so many mosquitoes in my yard specifically?
Usually there's water nearby, like a clogged gutter or tarp. Shady, damp plants give them a place to rest.
