Program Information
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
Morrow BioScience Ltd. provides the program in Golden and Electoral Area A and BWP Consulting Inc. provides the program for Revelstoke/Electoral Area B.
There had previously been a nuisance mosquito control program in the Scotch Creek and Lee Creek communities within Electoral Area F. Following a 2019 decision from the Little Shuswap Lake Indian Band to refuse to allow the CSRD to treat for nuisance mosquitos on their lands in the Hilliam Road area, the CSRD Board agreed to suspend the mosquito control program for the 2020 season. The Little Shuswap Indian Band’s decision, coupled with another recent decision from BC Parks to deny the CSRD’s application to conduct mosquito control in Shuswap Lake and Tsútswecw Provincial parks, would have made the program ineffective. Without the inclusion of these areas, the CSRD’s contractor recommended that the mosquito treatment program be abandoned.
The CSRD Board voted to suspend the program for the upcoming season only. CSRD staff will update the Board on the issue in the fall of 2020 to determine the next steps for the program in 2021.

Policy and the program
Mosquito 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.
Mosquito Facts
- Mosquitoes need standing water to develop.
- Mosquito habitats include ponds, sloughs, river flood plains, and tidal marshes.
- Man-made habitats include ditches, tires, bird baths, unused swimming pools, boats, eaves troughs.
- Only females bite because a blood meal is required for egg production.
- Some female mosquitoes take multiple blood meals and produce several generations during a single season.
- Only one mating is required to fertilize a lifetime of egg production.
- Mosquitoes can live from one to two months and others over winter to live up to a year or more.
- Mosquitoes can travel up to 20 miles.
- In the Canadian Arctic, mosquitoes can bite at the rate of more than 1,000 per minute.
Myths about Mosquito Control
Repellents
- Sound and Electric units are marketed with no test results and these devices have no repellent effects
- Citronella (plants and candles) - there is no data to support claims - pleasant odour does not guarantee results
- Skin Moisturizing Oil - field tests do not support claims
- Mosquitoes are 30 times more sensitive to DEET than to skin moisturizers
Control
- Bug Zappers - mosquitoes comprise less than 50% of the catch and usually kills more beneficial insects than mosquitoes. Bug Zappers actually attract mosquitoes.
- Birds - ornithologists state Purple Martins and other swallow-like birds do not like to eat mosquitoes which make up less than 3% of their diet.
- Bats - bat diets consist mainly of beetles, wasps, ants, flies, stoneflies, mayflies, moths and grasshoppers. Mosquitoes make up less than 10% of their diet.
Tips to Reduce Mosquito Annoyance
Since mosquitoes need water to complete their life cycle, the source of a mosquito problem can be just about anywhere water can collect. You can help reduce mosquito populations around the home by eliminating these sites and by:
- removing discarded containers from around your property;
- replacing water in bird baths and livestock troughs regularly;
- cleaning clogged eavestroughs, drain pipes and ditches; and storing boats, canoes and other objects so they do not collect rain water.
Mosquitoes are attracted to humans because of the heat, the carbon dioxide we exhale and fragrances in items such as soaps, perfumes, lotions, hair treatments and other personal-care products. To reduce the annoyance of mosquitoes:
- install and maintain tight-fitting window and door screens to help keep mosquitoes out of the home;
- wear light-coloured, loose-fitting clothing; and remember that heat and moisture from barbeques attracts mosquitoes;
- after cooking, move away to enjoy your meal.
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, 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.
