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.

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 Atlanta 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
Neither option replaces the basics. A pro should still dump and treat standing water every visit.
- 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, an Atlanta 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
Relief usually shows within a day or two.
- Time
- 20–45 minutes per visit, repeated every 3–4 weeks
- Best for
- Shaded yards with shrubs, ivy, and dense landscaping

Leaf-clogged gutters and downspouts hold water out of sight. Clearing them in fall means fewer places to breed in spring.How mosquito treatment works in Atlanta.
Barrier spray covers shady shrubs and leaves. Larvicide handles water you can't drain, like ponds or drains. Around Atlanta, the season runs from about April through October, so a plan usually starts in spring and runs to the end of the season. Then spray where the adults rest. First, find and remove the water where they breed. Treatment has two parts.

A year of mosquitoes in Atlanta.
- Spring: the first wave arrives early in Atlanta. Start treatments then. - Winter: a good time to fix drainage and low spots. - Fall: numbers stay high. Keep gutters clear of leaves. - Summer: with highs near 89°F in Atlanta, check water twice a week.
The weekly water walk.
- Saucers and pots: empty them or add sand. - Gutters: clear leaves so water drains. - Tree holes: fill them with sand. - AC drip lines and downspouts: make sure water drains away. - Pet bowls: refresh daily. - Birdbaths: change the water twice a week. - Tarps and covers: pull them tight so water runs off. - Toys and buckets: store them upside down.
Avoiding bites.
- Clothing: long sleeves and pants help at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus. - Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Screens: repair holes in window and door screens. - Fans: a patio fan keeps weak-flying mosquitoes away.
Low-cost ways to cut mosquitoes.
- Mosquito fish: they eat larvae in ornamental ponds. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds. - Lights: yellow bug lights attract fewer insects to the porch. - Trimming: thin out dense shrubs and tall grass. - Pumps and fountains: moving water breeds far fewer mosquitoes.
Mosquito or look-alike?
- Non-biting midges: swarm near water at dusk. Harmless, just annoying. - Crane flies: look like giant mosquitoes. They don’t bite. - Mosquitoes: slim, long legs, and a needle-like mouth. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh.
When a bite needs a doctor.
Spreading swelling or an infected-looking bite needs a check too. See a doctor for high fever, stiff neck or confusion. About one in five get a fever, headache or body aches. Most people infected with West Nile virus never feel sick. Most bites just itch for a few days.
Protecting your pets.
Talk to your vet about year-round prevention. Heartworm reaches dogs through mosquito bites, and cats can get it as well; Atlanta's season runs roughly May into December, so year-round prevention is the usual advice. Refresh pet water bowls daily; with about 50 inches of rain a year in Atlanta, bowls and plant saucers refill themselves. Keep animals inside until a yard treatment dries.
What a treatment visit looks like.
They dump or treat standing water. The tech walks the yard first. A visit usually takes 20 to 45 minutes. Most plans repeat every three to four weeks. Then they spray shady shrubs, where adults rest. Larvicide goes in water you can't drain.
Rain barrels and ponds.
- Ponds: fish and moving water keep larvae down. - Barrels: cover openings with fine mesh. - Pool covers: drain standing water after rain. - Tarps: shake out any that hold rainwater. - Gutters: clear them so water drains away. - Bird baths: change the water every few days.
Questions to ask before you sign.
- How often will you come? - What product will you spray? - When can kids and pets go back outside? - How do you protect bees and flowers? - What happens if bites come back between visits? - Do you treat standing water too?
What affects the price
- Standing water requiring larvicide.
- Travel distance from the company's base.
- Special-event timing and rush scheduling.
- Ponds, creeks, or wetland edges on the property.
- Misting system installation and refills.
- Re-treatment policy between scheduled visits.

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