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 New Brunswick 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

- 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

Questions people ask
What if the mosquitoes are coming from my neighbor's property?
Your local mosquito control district or health department can also help. Treat your own yard and talk to your neighbor. That's common.
Will mosquito treatment kill bees and butterflies?
Spraying when bees rest helps too. Ask them to skip blooming plants. It can if spray hits flowers.
What is the difference between larvicide and barrier spray?
