Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
The inspector checks resting spots too: dense shrubs, ivy, under decks, and shaded fence lines around your Brentwood home. Knowing where adults hide shows where barrier spray matters.
- Time
- 30–60 minutes
- Best for
- Every yard; finds where mosquitoes actually breed
Misting Systems and In2Care-Style Stations
misting $2,000–$4,500 installed plus refills; stations $200–$500 per season
For a Brentwood yard that hosts a lot of outdoor living, a fixed misting system releases insecticide from nozzles on a timer. It is the highest-cost option and needs regular refills.
- Time
- Misting: half a day. Stations: under an hour.
- Best for
- Specific yards: heavy outdoor use or spray-averse owners
Source Reduction and Larviciding
$75–$150 per visit
Where water cannot be drained, a pro applies a larvicide such as Bti or methoprene to stop larvae from becoming biting adults. Bti products are approved for rain barrels, ponds, and birdbaths.
- Time
- 45–90 minutes
- Best for
- Yards with standing water, clogged gutters, ponds, or drains
Barrier (Residual) Yard Treatment
$75–$200 per visit; $350–$900 per season

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 Brentwood.
Treatment has two parts. First, find and remove the water where they breed. Then spray where the adults rest. In Brentwood, 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.

A year of mosquitoes in Brentwood.
- Spring: dump water and clean gutters before May. - Summer: peak season in Brentwood, especially July and August. - Fall: activity fades with cooler nights. - Winter: fix drainage and store containers upside down.
The weekly water walk.
- 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. - Tree holes: fill them with sand.
Avoiding bites.
- 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. - Timing: tiger mosquitoes bite by day; house mosquitoes at dusk.
Low-cost ways to cut mosquitoes.
- 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. - Lights: yellow bug lights attract fewer insects to the porch.
Mosquito or look-alike?
- 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. - Mosquitoes: slim, long legs, and a needle-like mouth.
When a bite needs a doctor.
Most bites just itch for a few days. 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.
Protecting your pets.
Dogs get heartworm from mosquito bites. Cats can too. Ask your vet about year-round heartworm prevention. Change pet water bowls daily. Keep pets inside while a yard spray dries.
What a treatment visit looks like.
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. Then they spray shady shrubs, where adults rest. Most plans repeat every three to four weeks.
Rain barrels and ponds.
- 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. - Pool covers: drain standing water after rain.
Questions to ask before you sign.
- What product will you spray? - How often will you come? - Do you treat standing water too? - What happens if bites come back between visits? - How do you protect bees and flowers? - When can kids and pets go back outside?

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
The biggest win is free: dump standing water every week. Use repellent and run a fan on the patio. A pro adds larvicide for water you can't drain. They also spray where adults rest, every few weeks.
Mosquitoes in Brentwood
Brentwood gets about 50 inches of rain a year, so containers and low spots refill constantly through the season. Summer highs around 90°F in Brentwood speed up the life cycle, and average humidity near 69% keeps adults active. In Brentwood's neighborhoods, the usual sources are gutters, plant saucers, kids' toys and birdbaths. Brentwood has a humid subtropical climate, and mosquitoes activity here tends to pick up late spring through early fall; year-round in the deep south. In Brentwood, most of the housing is suburban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. In Brentwood, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Brentwood and Tennessee can point out the specific conditions that matter most here before you commit to a plan. In Brentwood, before you book, ask whether the inspection is included, what the treatment plan covers, how many visits to expect, and what the written quote includes. In Brentwood, getting the scope, the prep steps, and any follow-up terms in writing makes it much easier to compare providers fairly, and a good provider will walk you through each of these without pressure.

Questions people ask
What is the difference between larvicide and barrier spray?
It stops larvae from maturing. Barrier spray goes on leaves where adults rest. Most plans use both.
What does a mosquito inspection involve?
The tech walks the yard looking for standing water. They also check shady spots where adults rest. Gutters, saucers, tarps and low spots get checked first.
Is mosquito spraying safe for pets, kids, and bees?
Applied by the label, it's considered low risk once dry. Keep kids and pets inside until it dries. Ask them to avoid flowers.
What are In2Care stations and do they work?
They're small water traps. Mosquitoes visit, then carry larvicide to other water. They work best against container breeders like tiger mosquitoes.
Are misting systems worth it?
For a few homes, yes. They're costly to install and need refills. Most yards do fine with source removal and regular spraying.
What do most homeowners do about yard mosquitoes?
In Brentwood, mosquito control works by removing standing water, treating the water that cannot be drained, and applying barrier treatments where adults rest. In Brentwood, because they keep breeding through the season, an ongoing plan usually works best.
