Evacuation Order issued for Trozzo Creek wildfire and Octopus Cree wildfire - Evacuation Alerts issued for multiple areas »
There is a scheduled aerial application of Bacillus thuringiensis israelensis (Bti) granules to the Portion of Electoral Area D mosquito Control Service Area, probable to occur Sunday June 6, 2021; if for any reason the application is not able to commence, Monday, June 7, 2021 is the most probable back-up date.
Some properties have indicated no flyovers, and the pilot has been directed as such. The aerial application will likely start at the head of the lake and move north.
Mosquito season is upon us again. Within Meadow Creek and Pine Ridge, mosquito eggs laid in previous years along the banks and seepage sites of the Lardeau River (below Duncan Dam) and Kootenay Lake are hatching with the rising waters. Floodwater mosquitoes are triggered to hatch in the presence of water, typically from the freshet, and when the weather starts warming up.
Morrow BioScience Ltd. (MBL), the mosquito control contractor for the Regional District of Central Kootenay (Meadow Creek, Pine Ridge Program), has been conducting mosquito control within BC for over 40 years, and for over 20 years within the Meadow Creek and Pine Ridge region.
Residents may notice mosquito control contractors in brightly coloured vests sampling the flood and seepage waters for mosquito larvae – the targeted life stage for mosquito control. Once the mosquito eggs have hatched and the larvae have started to develop, mosquito control contractors apply a bacterial larvicide to the seepage water to kill the larvae. The larvicide is made up of bacterial spores targeting mosquitoes. When the mosquito eats the bacteria, it dies quickly. Mosquito development sites within the service areas will be monitored once or twice weekly through early August.
Mosquito control contractors have been applying the bacterial larvicide by ground since mid-May. Weather permitting, helicopter treatments will likely occur during the week of June 7-11. Both aerial and ground treatments may continue into August, as dictated by environmental conditions necessary for floodwater mosquito development. Because the larvicide is not toxic to people, wildlife, or pets, there are no safety restrictions following treatments.
We are doing our very best to reduce floodwater mosquitoes in your area. There are additional ways that residents can reduce container mosquito breeding sites around their properties. To reduce mosquito habitats, please remove or refresh standing water daily. These areas include bird baths, old tires, clogged gutters, animal troughs, and kiddy pools, to name a few. We also encourage residents to reduce their exposure to mosquito bites through personal protective measures such as wearing long-sleeved shirts and pants, choosing light-coloured clothing, using insect repellent, deploying mosquito netting at home, and ensuring window screens are properly installed and maintained.

The RDCK is renewing a Pest Management Plan and will submit the plan for approval under the Integrated Pest Management Act. This Plan will describe a Mosquito Control Program using Integrated Pest Management, including the use of insecticides.
Purpose: Mosquito Control for the purpose of nuisance control.
Application Method: Treatment of mosquito larval development sites by hand and aerial application.
Location: The areas to be included in this Pest Management Plan (PMP) application are limited to public and private lands within the following existing program areas:
Pesticide: Yearly totals up to, but not exceeding:
A selection of insecticides has been chosen to increase the ability to target mosquito populations in the most environmentally responsible method possible. All products listed are registered in Canada for the intended use. Bacillus thuringiensis var israeliensis has been chosen to control larval mosquitoes in their development sites. These pesticides are target specific, non-residual, and non-toxic.
The RDCK will not treat the total area of all the products listed above but will choose the best method to treat with the least environmental impact. All products are registered for mosquito control in Canada.
This project will begin April 30, 2021 and be completed by April 30, 2026.
A person wishing to contribute information about a proposed treatment site, relevant to the development of the pest management plan, may send copies of the information to the applicant at the address below.
Any member of the public wishing to view the application or associated material can do so online or by requesting a digital copy at the contact number below (arrangements can be made if digital access is not possible). If clarification is required regarding this application, please contact the applicant:

Since 2001 the RDCK has coordinated a mosquito control program in a portion of Electoral Area D (Duncan Dam) Service Area and the Pineridge Subdivision Service Area. Detailed information on the Mosquito Control Program. Here are some simple actions you can take right in your own backyard to help reduce local mosquito populations and make summer a little more comfortable.
The 2020 Final Report prepared by Morrow BioScience summarizes the 2020 mosquito control season.
The goal of the Program is to minimize the nuisance mosquito population to a tolerable level in the Area D-Duncan Dam and Pineridge Sudivision service areas. Contracted nuisance control activitied are undertaken in an effort to avoid negative impacts to the local economy and quality of life of our residents which can result from a high nuisance mosquito population. The RDCK's program is primarliy focused on larval mosquito control through ground and aerial application of biological larvacides, but may also involve additional work related to West Nile Virus surveillance and control.
