News Releases

The Office of the Chief Medical Officer of Health reports that preliminary analysis from adult mosquito traps for the week of June 23 has identified low numbers of Culex tarsalis mosquitoes in several communities in southern Manitoba.

 

Culex tarsalis larvae are beginning to be identified. Manitoba Health is advising participating municipalities in southern Manitoba to begin their Culex tarsalis larviciding programs.

 

The numbers of nuisance mosquitoes, which do not carry West Nile virus, have increased in the traps this week.

 

Culex tarsalis mosquitoes are the mosquitoes most likely to carry the West Nile virus. At this time, the risk of being bitten by a mosquito carrying West Nile virus is considered low but is expected to increase with the warm weather. 

 

The numbers of Culex tarsalis mosquitoes are expected to increase over the coming weeks.

 

To date, no human cases of West Nile virus have been identified in Manitoba in 2008.

 

Manitobans can reduce mosquitoes around their home by reducing standing water. To prevent the development of Culex tarsalis mosquitoes, homeowners can: 

·         clean eavestroughs and regularly empty bird baths and other items that might collect water,

·         ensure rain barrels are covered with mosquito screening or are tightly sealed around the downspout,

·         clear yards of old tires or other items that collect water, and

·         improve landscaping to prevent standing water around the home.

 

Manitobans can reduce the risk of mosquito bites by:

·         reducing the amount of time spent outdoors during peak mosquito hours between dusk and dawn;

·         using appropriate mosquito repellent;

·         wearing light-coloured, loose-fitting clothing; and

·         maintaining door and window screens so they fit tightly and are free of holes.
