The District of Sparwood has overseen the control of mosquitoes for many years. Businesses and recreational activities can suffer when the numbers of aggressive, daytime biting mosquitoes (known as ‘nuisance’ mosquitoes) rise to intolerable levels. The goal of the Nuisance Mosquito Control Program has been to reduce their numbers to tolerable levels using integrated pest management measures. Report nuisance mosquitos using the form on the right side of this page.
The program targets the aquatic stages of the mosquitoes (larvae and pupae), which are found in relatively discrete bodies of water, as opposed to mosquito adults, which once they emerge can spread over many square miles. Potential larval development sites are sampled at least once every seven days from May through June to determine if any larval treatment is required. In July and August, the frequency of surveillance is usually reduced to once every ten to fourteen days.
If the number of mosquito larvae found exceeds prescribed threshold levels, larvicide treatment is initiated using Bti (Bacillus thuringiensis israeliensis) (VectoBac ® 200G) which is extremely specific to mosquito larvae and has been shown to have minimal effect on other (non-target) organisms. The larvicide is applied as granules that have been impregnated with bacterial spores which emerge on contact with water. Mosquito larvae filter feed and ingest the bacteria with their food. The bacteria kill the mosquito larvae within a few hours. Bti persists in the environment for only a few days and is reapplied if necessary at ten day intervals. Mosquito larvae are one of the few organisms that possess an alkaline gut, and are capable of activating Bti. This is why Bti is specific to mosquitoes, and harmless to other organisms (dragonflies, ducks, dogs, birds, etc.) Treated sites will be checked within a few days after Bti treatment to determine if a new mosquito hatch has occurred.
To report instances of nuisance mosquitoes, get more information about the program or about mosquitoes in general, please contact the District of Sparwood at 250.425.6271, by email at firstname.lastname@example.org or use the online form. Please include your name, instance location and contact information when reporting instances of nuisance mosquitoes.
West Nile virus (WNv) is a mosquito-borne disease that cycles between mosquitoes and birds and can infect people and other animals through mosquito bites.
If you would like to report an unusual cluster of dead birds, please call the BC Interagency Wild Bird Mortality Investigation at 1-866-431-BIRD (2473). Reports will be recorded, assessed to determine if further investigation is warranted, and if so, guidance will be provided on a case by case basis.
