Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)

- 30–60 minutes
- Best for
- Every yard; finds where mosquitoes actually breed
Source Reduction and Larviciding
$75–$150 per visit
Expect some tips on this visit too, since you can clear most breeding sites on a New Orleans lot yourself. A pro points them out so they stay gone.

Misting Systems and In2Care-Style Stations
misting $2,000–$4,500 installed plus refills; stations $200–$500 per season

- 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

Local mosquitoes conditions in New Orleans.
A provider who works New Orleans and Louisiana every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Knowing New Orleans's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. An inspection in New Orleans usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around New Orleans, the area is mostly urban, so mosquitoes pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. New Orleans sits in a humid subtropical climate, and that sets the pace for mosquito activity here: late spring through early fall; year-round in the deep south.
Mosquitoes that bite indoors usually slip in through gaps around doors or torn window screens.Which mosquitoes bite around New Orleans.

Keep animals inside until a yard treatment dries.
