2005 Schedule of Adult Mosquito Control throughout Southern Manitoba under Ministerial Order

Several communities in southern Manitoba were issued a Ministerial Order in 2005 to undertake adult mosquito control to prevent or alleviate the threat of West Nile virus to human health. The Orders required that adult mosquito control be undertaken within a specific community and approximately a three kilometer radius zone around the community.

Adult mosquito control can be completed when weather conditions are conducive, i.e. when temperature is greater than 13 degrees Celsius and wind is less than 15 km/hr. If weather conditions are not conductive 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.

Health Canada finds the ultra-low volume application of malathion a safe practice for the control of adult mosquitoes that pose a nuisance or public-health hazard. However, general precautions are suggested any time pesticides are used 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,
washing any household items or toys left outside before using them, and
ensuring fruits and vegetables are washed.

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