What We Do

The Regional Nuisance Mosquito Control Program provides effective management of the insects through control of mosquito larvae in an environmentally friendly manner and to reduce the potential risk of West Nile Virus.

The Regional District administers this ongoing program on public lands in Kelowna, Lake Country and the Central Okanagan East and West Electoral Areas and a small area of West Kelowna Estates in the District of West Kelowna. 

From April through September, known breeding locations throughout the participating areas of the region are inspected for signs of mosquito larvae. If active breeding is found, environmentally-friendly larvicide pellets are spread into the water, which kills the larvae within 24 hours. The areas are visited to ensure there are no new hatches.  Roadside catch basins in the Electoral Areas, City of Kelowna and District of Lake Country are also inspected and treated as a pre-emptive approach to aid in West Nile Virus prevention.   

The areas that can be treated are specifically licensed under Provincial regulations. For example, larvacide pellets are not to be used in water that is connected to fish bearing water bodies.  The Regional District is in contact with public health officials and those from member municipalities to monitor the breeding conditions.

To report nuisance mosquito areas on public lands please call 1-866-679-8473. Please note that this number is to report mosquito problems only on public lands.

If you wish to report a dead raven, crow, magpie or jay (Corvid) that doesn't have any sign of injury or decay, please follow this link to complete an ONLINE REPORTING FORM

What Action Can You Take To Reduce Nuisance Mosquitoes and the risk of West Nile Virus?

  • Containers of water should be emptied or covered. This includes things like rain barrels, old tires, even saucers under plant pots! 
  • If you have a birdbath or wading pool you should change the water at least twice a week. 
  • If you have a pond, put fish in it so they'll eat the larvae.  Install a device to keep water circulating. 
  • Drain any areas of standing water.  Ensure eves troughs are clear and that water doesn't collect in them.
  • Water on top of pool covers can be a potential breeding source.  By placing a basketball or some other floating object underneath the cover, water won't gather on top of the cover.
