The purpose of Pest Management Plan (PMP) No. 141-Mosq-24/29 is to reduce overall mosquito annoyance for Regional District of North Okanagan (RDNO) residents, workers and visitors by controlling larval development using an Integrated Pest Management (IPM) approach to control. The PMP focuses on larval mosquito control initiatives and uses public education, physical site modification and biological controls to reduce larval mosquito populations and conserve or enhance natural mosquito predators wherever possible.

The proposed duration of the PMP is from 01 April 2024 to 31 March 2029. Larvicide products proposed for use include VectoBac 200G (PCP # 18158) or equivalent, which contains the natural-occurring soil bacterium Bacillus thuringiensis var. israelensis, and VectoLex CG (PCP # 28008) or VectoLex WSP (PCP # 28009) made with the related bacterium Bacillus sphaericus. These products are classified as bio-rational products, they are non-persistent, do not accumulate in the environment and provide species- specific control of mosquito larvae. They are non-toxic to other organisms including insects, fish, birds, amphibians, reptiles, wildlife, man and domestic animals.

Mosquito larvae require stagnant or non-flowing waters, temporary or permanent, to develop. Development habitats include river or lake level influenced floodwaters, marshes, ponds, ditches and catch basins. When physical alterations (drainage, filling) are neither practical nor desirable, developing larvae will be treated using the appropriate larvicides. Applications of the granular larvicide products VectoBac and VectoLex will be made using aerial (helicopter) and ground-based, hand- broadcast, or backpack applicator methods. All applications will be conducted within, and adjacent to, the RDNO communities of Mabel Lake, Grindrod, Ashton Creek, Kingfisher and Lumby. Included are all crown, provincial, municipal, regional district, First Nation and private lands, with permission of the applicable landowners, authority or agency. Total treatment area may exceed 500 hectares of public lands in each year of the PMP.
