How to request service

What they will and won't do

Public education and removing standing water are common parts of mosquito programs. Larval control may target public water, ditches and catch basins. Adult mosquito treatment follows local program criteria; a complaint is not a promise of spraying. Inspection eligibility, fish availability, pickup or delivery, response times and seasons vary. Public programs generally do not provide routine yard spraying or event protection on demand. Confirm your address with the agency: ZIP codes and county names do not establish district coverage.
