Barrie Mosquito Bylaw - Abatement Program & Complaints

Public Health and Welfare Ontario 3 Minutes Read · published May 24, 2026

· By Daniel Roy

Barrie, Ontario operates a municipal mosquito abatement program to reduce nuisance biting and vector risk while following provincial pesticide rules and public-health guidance. This page explains the program schedule, how to report concerns or complaints, the roles of By-law Enforcement and Public Works, and what to expect about inspections, permits and appeals.

Program scope, schedule and methods

The City schedules larviciding and targeted control during peak season based on surveillance and complaints. Treatments typically focus on known breeding areas and public health priorities; the City posts seasonal notices and maps for planned work ^[1]. The program uses larvicides and source reduction rather than broad adulticiding unless required by public-health advice.

Check the City schedule pages before planning outdoor events.
