An SFU entomologist answers our questions about a bad bug season and what to do about it
Carl Lowenberger is a professor in Simon Fraser University’s department of biological sciences who specializes in bugs, parasites and how they can be vectors for diseases that negatively affect animal and human health.
The other species, and the troublesome one this summer — Aedes — lays eggs that overwinter instead. They don’t lay them in water but just above it, such as on riverbanks. In spring, when the weather warms, the snowpack melts and rivers rise, the water activates the eggs into action. Cue the swarm. The current forecast for warm to hot, dry weather through the last part of July is exactly what mosquitoes don’t need to continue hatching. “Probably by mid-August most will be gone, I expect.”
In theory, we could see disease transmission from mosquitoes on the coast, but there just aren’t enough of those problematic pathogens around. Someone could, for instance, catch Dengue fever while travelling to an area where it’s endemic and bring it back. It just doesn’t occur here except in exceedingly rare cases.This advertisement has not loaded yet, but your article continues below.That’s not the case everywhere in Canada.
