There are approximately 150 different species of mosquitoes that can be found in Canada.

A few mosquito species can be vectors of disease. Culex Pipiens is the principal vector of West Nile Virus and Saint Louis encephalitis and is one of the main vectors of dog heartworm. To the naked eye, it is tough to distinguish one mosquito species from another.

The most common species found in the urban environment is the Culex pipiens. This species has a unique venation and striping on its abdomen. Adult female mosquito deposits multiple eggs in “rafts” in a variety of aquatic situations. The larval development time and survival rate depends on temperature, diet and population densities. Once the larvae complete their development they will molt into C-shaped pupae. The pupae molt into adults which then mate and the female begins her search for a blood meal so that she may deposit her eggs.

Male mosquitoes do not bite. Only the female mosquito will bite as it needs a blood meal to deposit its eggs. Female Mosquitoes locate people by detecting CO2 and lactic acid that people emit. Mosquitoes are attracted to certain colours of clothing and are attracted to light blue more than any other colour.

The Mosquito larvae can be found breeding in artificial containers such as gutters, sewers, swimming pools, bird baths, rain barrels. It is highly recommended that any pesticide applications be left up to a licenced pest control applicator. You can assist in the control process by removing the breeding water sources mentioned.
