Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
Around your New Iberia home, the inspector also checks where adults rest: dense shrubs, ivy, under the deck and along shady fences. Knowing where adults hide shows where barrier spray matters.
- Time
- 30–60 minutes
- Best for
- Every yard; finds where mosquitoes actually breed
Source Reduction and Larviciding
$75–$150 per visit
Most breeding sites on a New Iberia lot can be cleared by hand, so this visit is also a chance to learn what to look for. A pro points them out so they stay gone.
- Time

- Best for
- Specific yards: heavy outdoor use or spray-averse owners
