Mosquitoes

Managed by Metro Vancouver, the goal of Surrey's Nuisance Mosquito Control Program is to regulate mosquito populations to tolerable levels using environmentally friendly integrated pest management techniques.

The program primarily targets the control of floodwater mosquitoes that can emerge in large numbers in the spring and early summer, usually following the spring freshet caused by snow melting in the mountains.

Monitoring Mosquito Habitats

Mosquito habitats are identified through targeted routine monitoring and responses to citizen concerns. Monitoring occurs during the mosquito season (May through September). This involves strategic sampling of wetted areas suspected to be occupied by mosquito larvae.  Monitoring of the identified areas is performed regularly throughout the season by qualified contractor mosquito technicians.

Control of Mosquito Larvae

If larvae numbers become too high, population management may be done using bacterial Bacillus larvicides. The larvicide toxins are highly specific and will not affect humans, pets, birds, fish and other non-target organisms. They provide long-term residual control of mosquito larvae. Larvicides are regulated in Canada and the products are used according to provisions of the product label.

The larvicide used for mosquito control in Surrey is Aquabac. The mosquito control contractor for the Nuisance Mosquito Control Program is Morrow BioScience. They're responsible for the program on behalf of Metro Vancouver and the five member municipalities.

West Nile Virus

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. Through biting different animal hosts, a few species are capable of transmitting certain diseases and parasites to which mammals, including humans, are potentially susceptible.

Due to the lack of any serious outbreaks of WNv in the Lower Mainland and Fraser Valley, and following directives from the BC Centre for Disease Control and Fraser Health Authority in 2012, municipalities are no longer conducting WNv risk reduction programs.

Reduce the Risk of Mosquito Bites

The best protection is to avoid mosquito bites and reduce mosquito populations in your home and yard. We recommend:

  • Use insect repellent when outdoors
  • Avoid mosquito-laden areas during dawn and dusk
  • Wear loose, light coloured clothing when outdoors, including long-sleeved shirts and pants
  • Apply tight-fitting, well maintained screens to doors and windows
  • Keep your lawn regularly mowed to decrease mosquito rest areas
  • Eliminate or regularly changing any sources of stagnant water around your home such as saucers under flower pots, bird baths, wading pools, boat tarpaulins, and other areas where rainwater may collect

Prevent Mosquito Breeding

In order to prevent mosquito breeding, follow these tips:

  • Dispose of tin cans, old tires, buckets, plastic sheeting, or other containers that collect and hold water
  • Clean bird baths regularly
  • Repair leaky plumbing and outside faucets
  • Clean out leaves and other debris blocking and holding water in roof gutters
  • Empty your pets' water dishes daily
  • Water lawns and gardens carefully to prevent water from standing for several days
  • Empty or cover swimming and wading pools when not in use
