Summary of Mosquito Provisions Amendments

The mosquito provisions in the Minister's and Administrator's regulation were amended to address the following issues:

Mosquito control activities in response to a BC Centre for Disease Control advisory of a West Nile Virus (WNV) outbreak:

  • Allow application of bacterial pesticide to permanent fish bearing waters under a PMP confirmation.
  • Allow application of bacterial pesticide or methoprene to a storm drain that drains directly to fish bering waters.
  • Allow for reduction in 30 days public consultation period required for a permit if a Medical Health Officer believes that a delay in pesticide use will cause negative impacts to human health.

Requirements relating to all mosquito control activities:

  • Treatment of storm drains with methoprene (growth regulator) and bacterial pesticides requires a service licence; no longer requires a permit.
  • Requires contact with Drinking Water Officers to determine the locations of water intakes prior to applications of methoprene to storm drains in order to prevent the contamination of drinking water.
  • Requires notification to registered bee keepers when adulticiding to prevent bees being exposed to pesticides.
  • Include Bacillus sphaericus in Schedule 4 (does not require permit for aerial application).

The amendments are available on the ministry website:
