Notice: Aerial Treatment for Nuisance Mosquitos in Lower Nicola and Douglas Lake Areas

Kamloops, BC – June 7, 2024 – The Thompson-Nicola Regional District (TNRD) Nuisance Mosquito Control program will be administering aerial treatments for nuisance mosquitoes in the Lower Nicola and Douglas Lake areas during the week of June 10, 2024. Application involves the use of a low-flying helicopter that will apply Vectobac to infested areas.

Vectobac is an organic water-dispersible granule formulation of Bacillus thuringiensis, a bacterial larvicide that is used to control of mosquito larvae. Vectobac is not harmful to fish, mammals, amphibians, reptiles, insects, livestock or human.

Management activities will be carried out in accordance with the TNRD’s Mosquito Surveillance  & Reduction Pest Management Plan.

About the TNRD’s Nuisance Mosquito Control Program

The TNRD Nuisance Mosquito Reduction Program includes mosquito reduction with organic pesticides, mosquito surveillance, and outreach to the public. The TNRD began its mosquito reduction program in 1971. At first, the program consisted of aerial applications to control adult populations of mosquitoes. With the advancement of new products such as biological larvicides, which do not harm fish habitats, the program has shifted over time to an environmentally-safe practice: controlling mosquito larval populations before they become adults.

Nuisance Mosquito Reduction is conducted in the following areas of the TNRD:

  • A portion of Electoral Area “A;”
  • Electoral Areas “J,” “L,” “M,” “N” (excluding lands adjacent to the Coquihalla Recreation Area), “O” and “P;” and
  • Member municipalities including Barriere, Chase, Clearwater, Kamloops, Logan Lake and Sun Peaks.
