Recent heavy rainfall in Edmonton has led to a surge in mosquito activity, with the city expecting a significant increase in mosquito populations soon. According to Mike Jenkins, a senior scientist from the City of Edmonton, this spring already witnessed the highest local mosquito numbers in years. The continuous heavy rains, especially in early June, have created ideal conditions for mosquito breeding, with the ground saturated and forming temporary habitats for mosquito development.
After years of drought, dormant mosquito eggs are now hatching due to the moist soil and standing water. Female mosquitoes, depending on the species, will soon be ready to draw blood after hatching. The increase in mosquito numbers is a result of the activation of dormant eggs by the recent precipitation.
City crews are actively targeting known mosquito breeding habitats to control the population. The increase in mosquito numbers is a concern, especially with the arrival of a new mosquito species, Culex pipiens, known to carry the West Nile virus. To combat the mosquito population, the city’s program focuses on killing larvae before they hatch, using biological larvicides rather than spraying for adult mosquitoes.
While the risk of disease transmission remains a concern, research shows that mosquitoes tend to bite birds rather than humans. The most common mosquito species in Edmonton, Aedes vexans, is expected to be the prevalent pest this summer, known for its biting activity during dawn and dusk. Residents are advised to cover up and eliminate standing water on their properties to reduce mosquito breeding grounds.
Mosquito numbers have already begun to climb, with traps capturing a significant increase in mosquitoes over a short period. Edmontonians are urged to take precautions to avoid mosquito bites as the city braces for a potentially challenging mosquito season ahead.
