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

- 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

Local mosquitoes conditions in Medford.
An inspection in Medford usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Around Medford, the area is mostly suburban, 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. Medford sits in a mediterranean climate, and that sets the pace for mosquito activity here: late spring through early fall; year-round in the deep south. A provider who works Medford and Oregon 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 Medford'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.

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.
