Mosquito abatement schedule and notices

Halton Region publishes planned larviciding and adulticiding schedules, nightly operational summaries, and interactive maps for targeted treatments. Notices typically include dates, target neighbourhoods, product names, and the reason for treatment. Schedules are subject to change for weather and surveillance results; residents within treated zones are notified before operations when possible. For the official notification list and details on how the Region decides spray areas, see the regional notifications page cited aboveHalton Region mosquito program[2].

Spray decisions are based on surveillance data and public-health thresholds.
