Treatment options and typical costs
Property Inspection for Breeding Sites

- 30–60 minutes
- Best for
- Every yard; finds where mosquitoes actually breed
Monitoring and Seasonal Plans
$50–$150 per follow-up visit; $350–$900 per season bundled
A good pro checks landing counts between visits. Numbers climbing early means a missed breeding site.
- Time
- 15–30 minutes per check; season runs spring through first frost
- Best for
- Anyone who wants the yard usable all summer
Misting Systems and In2Care-Style Stations
misting $2,000–$4,500 installed plus refills; stations $200–$500 per season
Stations suit small Auburn lots, townhome yards, and properties where the owner would rather not have spray. They work slowly, so pair them with source reduction.

- Specific yards: heavy outdoor use or spray-averse owners
Barrier (Residual) Yard Treatment
$75–$200 per visit; $350–$900 per season
Crews should skip blooming plants and vegetable beds when spraying an Auburn property to protect bees and food crops. A careful applicator treats resting cover, not the whole yard.

- Best for
- Shaded yards with shrubs, ivy, and dense landscaping

A treatment visit covers the shaded plants and beds where adults rest, along with any standing water that can't be drained.How mosquito treatment works in Auburn.
First, find and remove the water where they breed. Then spray where the adults rest. Across Auburn, the season runs from late May until the first frost, 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 Auburn.
They breed in storm drains. They're the main West Nile carriers. Floodwater mosquitoes hatch in big waves after heavy rain or snowmelt. They can travel a long way from where they hatch. House mosquitoes (Culex) bite from dusk into the night.
Mosquitoes that bite indoors usually slip in through gaps around doors or torn window screens.Mosquito season in Auburn.
The season is short, but numbers can spike after rain. West Nile cases usually peak in late summer.
A year of mosquitoes in Auburn.
- Winter: store containers upside down and plan for spring. - Spring: clean gutters and dump water as snow melts. - Summer: short but busy in Auburn. Watch for swarms after rain. - Fall: the first frost ends the season.
The weekly water walk.
- Tree holes: fill them with sand. - Gutters: clear leaves so water drains. - 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.
Avoiding bites.
- Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus. - 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.
Low-cost ways to cut mosquitoes.
- Lights: yellow bug lights attract fewer insects to the porch. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds. - 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.
Mosquito or look-alike?
- Mosquitoes: slim, long legs, and a needle-like mouth. - Crane flies: look like giant mosquitoes. They don’t bite. - Non-biting midges: swarm near water at dusk. Harmless, just annoying. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh.
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.
Talk to your vet about year-round prevention. Refresh pet water bowls daily, dump saucers after Auburn's summer storms, and keep animals inside until a yard treatment dries. Heartworm reaches dogs through mosquito bites, and cats can get it as well; Auburn's June–October season is long enough that most vets advise year-round prevention.
What a treatment visit looks like.
The tech walks the yard first. They dump or treat standing water. 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.
Rain barrels and ponds.
- Pool covers: drain standing water after rain. - Barrels: cover openings with fine mesh. - 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.

What's your biggest concern about mosquitoes?
When to call for help
early in the season, before the first big wave. Ponds, drains and dense shrubs are hard to handle yourself. Call if bites still keep you indoors. Dumping water should come first.
What you can do yourself
A pro adds larvicide for water you can't drain. They also spray where adults rest, every few weeks. The biggest win is free: dump standing water every week. Use repellent and run a fan on the patio.

Questions people ask
When should mosquito treatments start each year?
Before the first big wave. Around Auburn, the season runs from late May until the first frost, so start a few weeks before.

Applied by the label, it's considered low risk once dry. Keep kids and pets inside until it dries. Ask them to avoid flowers.
