Winnipeg, MB - In response to the recent significant rainfall of up to 180 mm in the City, the Insect Control Branch has aggressively larvicided to control mosquito populations. These measures alone are no longer sufficient to control the nuisance mosquito population so an adult nuisance mosquito fogging program will be implemented. Fogging will begin on Saturday, July 27, 2019, between 9:30 p.m. and 6:30 a.m.
Adulticiding Factor Analysis (AFA)
Based on the Adulticiding Factor Analysis (AFA) factors, which include trap counts, the city-wide AFA rating moved from MEDIUM to HIGH on Friday, July 26, 2019.
Today, the city-wide New Jersey Light Trap count is 104.
In order for a nuisance mosquito fogging program to occur, the City of Winnipeg Adult Nuisance Mosquito Control Policy and the Provincial Pesticide Use Permit define three conditions that must be met:
- The Adulticiding Factor Analysis, which is one city-wide rating, must be HIGH; and
- A minimum city-wide average trap count threshold of 25 female mosquitoes for 2 consecutive nights; and
- One or more of the quadrants of the city are in the range of 100 female adult mosquitoes.
At this time, all of these conditions have been met.
Daily public service announcements
Public Service Announcements (PSAs) will be released daily at least eight hours in advance of fogging. These PSAs will identify the Insect Management Areas the Insect Control Branch is planning to treat that evening, weather permitting. Until further notice, fogging will be carried out on a daily basis between the hours of 9:30 p.m. and 6:30 a.m. Fogging will not occur when temperatures are below 13 degrees Celsius and/or wind speeds are not conducive to fogging.
The insecticide DeltaGard® 20EW will be used. This insecticide has been approved for use in Canada by Health Canada’s Pest Management Regulatory Agency. DeltaGard® 20EW will be used in accordance with federally approved label directions by licensed pesticide applicators.
Register for notification
The Insect Control Branch offers an automated telephone and email notification system. Residents who register for this service will receive daily phone or email notifications for adult mosquito control activities. To register for the automated email or telephone notification system, residents can go to City of Winnipeg – Register for Notification or contact 311.
Buffer zones
All buffer zones will be respected. Crews will ensure that the sprayer is not treating within 90 metres on each side of a registered property on the front street, side street, and rear lane.
Property owners not wanting insecticides applied on or adjacent to their principal residence may register as “Anti-Pesticide Registrants” (APR) for the adult nuisance mosquito control program. Those who wish to register must provide identification that ties the registrant to the address being registered for a buffer zone. A photocopy or scanned document such as a driver’s licence or a utility bill will suffice as acceptable identification proving primary residence. Remember – a 72-hour turnaround time is required.
There are three different options to register:
- In writing to the Insect Control Branch at 3 Grey Street, Winnipeg, MB R2L 1V2
- Contacting 311
- In person at 1539 Waverley Street
