$0–$150 (often bundled with a first treatment)

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

Local mosquitoes conditions in Florence.
A provider who works Florence and Kentucky 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. Florence 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. Across Florence, 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. An inspection in Florence usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Florence'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.

When a bite needs a doctor.
Most people infected with West Nile virus never feel sick. About one in five get a fever, headache or body aches. See a doctor for high fever, stiff neck or confusion. Spreading swelling or an infected-looking bite needs a check too. Most bites just itch for a few days.
