Nuisance Mosquito Control Program

The City participates in the Metro Vancouver Regional Nuisance Mosquito Control Program. This environmentally-sensitive program is designed to reduce nuisance mosquito populations to tolerable levels by aiming to control mosquitoes at the larval stage of the mosquito life cycle.

Larval Mosquito Control

The primary emphasis is to target mosquito larvae confined to a specific location (i.e. found in stagnant bodies of water such as sloughs, seasonal wetlands, detention ponds, and/or roadside ditches). The program involves:

  • surveillance
  • identification
  • data collection
  • monitoring
  • treatment of mosquito-producing sites

When sites meet regulated levels, specific identified surface water is treated with environment-friendly larvicide Bacillus thuringiensis israelensis coated pellets by these two effective scientific methods:

  • hand or backpack spreader via foot or boat access
  • aerial spreading dropped from a helicopter

Nuisance mosquito species are not typically associated with the spread of West Nile virus.

Other Control Methods

Adulticiding, the spraying or fogging of insecticide to control adult mosquitoes, is considered an extreme last resort option and is not used as a primary means of mosquito control.

It is important to note that due to human health and environmental risks associated with airborne distribution of insecticide, adulticide mosquito control methods have not been used in the City since 2004. This method would likely only be used under specific direction of the Medical Health Authority, such as in an outbreak of West Nile virus.
