Mosquito populations in Edmonton potentially decreasing due to heat wave, suggests expert
In the city of Edmonton, the dry conditions experienced since spring have resulted in a significant reduction in mosquito populations, a welcome development that also lowers the risk of mosquito-borne diseases, such as West Nile virus, in the area.
The decrease in mosquito numbers is due to the fact that these pests require standing water to complete their life cycle. With the lack of moisture, fewer mosquitoes develop and survive, creating a more mosquito-free environment.
Interestingly, the mosquito species prevalent in Edmonton tend to prefer biting birds over humans. This preference decreases the immediate risk to people, as the mosquito that carries West Nile virus usually bites birds to get the blood needed for egg growth. However, it's important to note that while the species caught by the city are not known to vector West Nile virus, there are species in the area that could potentially carry the virus.
To further reduce the risk of mosquito-borne diseases, homeowners should take preventative measures. Eliminating standing water around homes is crucial, as it is a breeding ground for mosquitoes. This includes regularly emptying bird baths, watching for flowerpots and other items that may collect standing water, and ensuring there is little standing water in their backyard.
The first human case of West Nile virus was recently confirmed in Toronto, serving as a reminder of the importance of these preventative measures. For those concerned about West Nile virus, the best defense starts at home. By taking simple steps to eliminate standing water and reduce mosquito populations, residents can help protect themselves and their communities from this mosquito-borne disease.
The decrease in mosquito populations in Edmonton, while beneficial for health and wellness, does not exclude the presence of West Nile virus-carrying species in the area. Thus, the implementation of health-and-wellness practices, such as eliminating standing water, becomes crucial in environmental-science to minimize the risk of mosquito-borne diseases.
