Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
Most mosquitoes biting you in West Palm Beach were born within a few hundred feet of your door, so the inspection maps every container, drain, and puddle on the lot. That map becomes the treatment plan.
- Time
- 30–60 minutes
- Best for
- Every yard; finds where mosquitoes actually breed
Source Reduction and Larviciding
$75–$150 per visit
Because larvicide works on mosquitoes that can't fly away yet, it's the foundation of most plans in West Palm Beach. Adult spraying is the follow-up, not the fix.
- 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
Crews should skip blooming plants and vegetable beds when spraying a West Palm Beach property to protect bees and food crops. A careful applicator treats resting cover, not the whole yard.
- Time
- 20–45 minutes per visit, repeated every 3–4 weeks
- Best for
- Shaded yards with shrubs, ivy, and dense landscaping
Misting Systems and In2Care-Style Stations
misting $2,000–$4,500 installed plus refills; stations $200–$500 per season
For a West Palm Beach 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.

- Best for
