Mosquito crews return to treat roadside catch basins

Mobile crews return for a second round of roadside catch basin treatments in the Central Okanagan. Water-soluble larvicide pouches will be used in catch basins to prevent mosquito development, reducing nuisance levels and lowering the risk of mosquito-borne illnesses such as West Nile virus.

This work complements the RDCO’s broader annual mosquito surveillance and control program, which focuses on identifying and treating standing water sites where mosquito larvae develop. Since April, crews from Duka Environmental Services Ltd. have monitored more than 200 locations, including ponds, marshes, swamps, seepage areas and temporary water accumulations, applying a biological larvicide that specifically targets mosquito larvae.

Residents also play a critical role in limiting mosquito populations. Even small actions can significantly reduce mosquito development habitat around homes.

Reducing mosquito development around homes

Standing water is the primary development habitat for mosquitoes, and only a few millimetres are needed for larvae to develop. Residents are encouraged to inspect their properties and take these steps at home:

• Empty standing water from plant pots, buckets, garbage cans, spare tires, gutters and pool covers
• Ensure rain barrels are sealed with tightly fitting lids or screened openings
• Replace water in birdbaths, pet dishes and wading pools at least twice weekly
• Maintain ponds through aeration or by introducing fish that feed on mosquito larvae

Encouraging natural predators, including birds, bats and dragonflies, can further help manage mosquito numbers.

Regional program delivery

The RDCO mosquito control program is delivered across multiple participating areas, including the City of Kelowna, District of Lake Country, District of Peachland, Westbank First Nation, the Sunset Ranch community in the Central Okanagan East Electoral Area and a portion of West Kelowna Estates.

Field crews use a range of vehicles including pickup trucks, scooters and e-bikes to access treatment sites. Staff will be clearly identifiable, wearing high-visibility safety vests, and all vehicles and equipment will display mosquito control signage. Residents are asked to provide crews with additional space, particularly along roadside curbs and bike lanes.

Residents in participating areas can report mosquito concerns online at rdco.com/mosquitoes or by contacting Duka Environmental at 1-800-681-3472.
