Mosquito Control

Close Up of a Mosquito

The CSRD currently administers mosquito control programs for the reduction of the nuisance effect of mosquitos in:

  • Golden and Electoral Area A
  • Revelstoke and Electoral Area B
  • Scotch Creek (Program reinstated for 2023)

Morrow BioScience Ltd. provides the program in Golden and Electoral Area A and BWP Consulting Inc. provides the program for Revelstoke/Electoral Area B and Scotch Creek/Lee Creek.

Mosquito Control in Scotch Creek - 2023

The CSRD, BC Parks and the Skw'lax te Secwepemcúl̓ecw (Little Shuswap Lake Band) will restart the mosquito control program in the Scotch Creek/Lee Creek Service Area area in 2023.

In 2022, the CSRD and Skw'lax te Secwepemcúl̓ecw partnered to cover the cost of an independent study conducted by Simon Fraser University, led by the Skw'lax te Secwepemcúl̓ecw. The study concluded there were no adverse impacts of Aquabac on fish or their habitat. Based on the conclusions of the independent research, the Skw'lax te Secwepemcúl̓ecw are now willing to move forward with the nuisance mosquito program on a one-year basis.

The purpose of the one-year basis is to allow for testing on amphibians during the 2023 season.  Based on test results, the program will be re-evaluated and long-term agreements may be negotiated.

BC Parks is also on board with the mosquito control plan and issued a letter of authorization for the treatment of habitat in Shuswap Lake Provincial Park between April and August 2023. BC Parks no longer authorizes treatment in Tsútswecw Park, impacting the effectiveness of program delivery in the Lee Creek area.

Policy & the Program

Helicopter Over TruckMosquito control programs administered by the CSRD are developed and delivered to address the control of nuisance and annoyance factors associated with mosquito activity. The Regional District's mosquito program is not directed at controlling or addressing the health impact of mosquitoes, including in relation to the West Nile Virus. The Regional District will not be investigating, responding to or in any way addressing the potential health impact of mosquitoes as part of this program.

Break the Cycle

A pro-active control program concentrates efforts on the physical and biological control of larvae before they become a nuisance. The most permanent prevention of adult mosquito annoyance is through the physical reduction of the problem, at the source. Where draining and filling of wetlands and other mosquito habitats is impractical and undesirable, an overall reduction of adult mosquitoes is best achieved through larval control. 

Biological control using the product VectoBac 200G and Vectobac breaks the cycle by controlling larvae. This material contains a naturally occurring bacterium commonly known as Bti (Bacillus thuringiensis var. israelensis). It has no harmful effects on beneficial insects, frogs, fish, birds or mammals.
