- Larvicide handles water you can’t drain.
- Use repellent with DEET, picaridin or IR3535.
Anyone in Orlando tired of mosquito bites at home.
What to look for
Often the source is a neighbor's yard or a storm drain. In summer heat, eggs become biting adults in about a week. Mosquitoes breed in standing water, even a bottle cap's worth.
- 1Corrugated downspout extensions that never drain.
- 2Mosquitoes indoors resting on walls or in closets.
- 3Bites getting worse after each wet spell.
- 4A neighbor's pool turning green and untended.
- 5Being bitten in full daylight, not just evening.
- 6Wriggling larvae in birdbaths, buckets, or saucers.
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.

Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
An inspection in Orlando also gives you a realistic idea of how much a treatment can do on your lot. A wetland yard is a different job from a dry cul-de-sac.
- 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 an Orlando 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
Barrier (Residual) Yard Treatment
$75–$200 per visit; $350–$900 per season
Barrier spray is the workhorse of mosquito control in Orlando, but it is only as good as the coverage of vegetation. Open lawns hold few adults; hedges and ivy hold thousands.
- Time
- 20–45 minutes per visit, repeated every 3–4 weeks
- Best for
- Shaded yards with shrubs, ivy, and dense landscaping
Source Reduction and Larviciding
$75–$150 per visit
This visit often doubles as homeowner coaching, since most breeding sites on an Orlando lot can be eliminated by hand. A pro points them out so they stay gone.
- Time
- 45–90 minutes
- Best for
- Yards with standing water, clogged gutters, ponds, or drains
Prices are typical published ranges. Ask what’s included before you compare quotes.
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 Orlando.
First, find and remove the water where they breed. Then spray where the adults rest. Across Orlando, the season runs nearly all year, 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 Orlando.
They're black-and-white and bite by day. They breed in small containers. Yellow fever mosquitoes live around Orlando too. They also bite by day, often near or inside homes. House mosquitoes (Culex) bite from dusk into the night. They breed in storm drains. They're the main West Nile carriers. Asian tiger mosquitoes are common around Orlando.
Mosquitoes that bite indoors usually slip in through gaps around doors or torn window screens.Mosquito season in Orlando.
There's no real off-season, so steady habits matter more than timing. West Nile cases usually peak in late summer.
A year of mosquitoes in Orlando.
- Fall: the season keeps going. Keep gutters clear of leaves. - Winter: activity drops but doesn't stop. Keep dumping water. - Spring: numbers climb fast. Start treatments early. - Summer: with highs near 92°F in Orlando, check water twice a week.
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; with about 52 inches of rain a year in Orlando, bowls and plant saucers refill themselves. Keep animals inside until a yard treatment dries. Heartworm reaches dogs through mosquito bites, and cats can get it as well; Orlando's season runs roughly May into December, so year-round prevention is the usual advice.
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.
Questions to ask before you sign.
- When can kids and pets go back outside? - 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?
What affects the price
- Lot size and total acreage treated.
- Re-treatment policy between scheduled visits.
- Amount of shade and dense vegetation.
- Misting system installation and refills.
- Standing water requiring larvicide.

What's your biggest concern about mosquitoes?
When to call for help
Call if bites still keep you indoors. Dumping water should come first. early in the season, before the first big wave. Ponds, drains and dense shrubs are hard to handle yourself.

Mosquitoes in Orlando
Orlando gets about 52 inches of rain a year, so containers and low spots refill constantly through the season. Summer highs around 92°F in Orlando speed up the life cycle, and average humidity near 74% keeps adults active. In denser parts of Orlando, storm drains, catch basins and gutters are big breeding spots. Orlando has a humid subtropical climate, and mosquitoes activity here tends to pick up late spring through early fall; year-round in the deep south. Across Orlando, most of the housing is urban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Across Orlando, 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 Orlando and Florida can point out the specific conditions that matter most here before you commit to a plan. Across Orlando, 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. Across Orlando, 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
How long does a mosquito treatment last?
A barrier spray usually lasts three to four weeks. Heavy rain can shorten that.
What should I do before the pro arrives?
Dump standing water. Move toys and pet bowls. Tell them where you get bitten most.
