2007 Schedule of Adult Mosquito Control throughout Southern Manitoba under Ministerial Order

As of September 6, 2007

No new orders under Manitoba’s Environment Act are being issued to control adult mosquitoes at this time. Adult mosquito control based on orders previously issued is not indicated at this time.

---

Mosquito spraying will take place in the evening and at night, weather conditions permitting. Information on adult mosquito control schedules for West Nile virus and a description of the areas to be sprayed are available below. Adult mosquito control cannot occur when weather conditions are unfavourable, i.e. when temperature is below 13 degrees Celsius, when wind speeds are not conducive, and if there is significant precipitation. If weather conditions are not conducive to adult mosquito control on the identified night, alternate arrangements will be made to undertake adult mosquito control usually the next consecutive night, as weather permits.

Communities in southern Manitoba may be issued a Ministerial Order to undertake adult mosquito control to prevent or alleviate the threat of West Nile virus to human health. The Order may require that adult mosquito control be undertaken within a specific community and may include approximately a three kilometre extended treatment area around the community. Mosquito control occurs under the direction of an entomologist designated by Manitoba Health and may target specific population areas within a municipality.

Health Canada has concluded that the use of malathion for adult mosquito control in residential areas using ultra-low-volume applications will not pose a health concern. However, people who wish to reduce their exposure to malathion can take precautions, including:

• closing all doors and windows,
• avoiding trucks while spraying is underway,
• turning off fans and air conditioners or setting them at exhaust,
• removing clothes and children’s toys from outdoor areas,
• rinsing any household items or toys left outside before using them, and
• washing fruits and vegetables.

For more information on malathion, visit the Pest Management Regulatory Agency (PMRA) website.
