Swarms of tiny bugs are invading Toronto as part of their annual mating frenzy

It's officially that time of year again, when stepping outside for a stroll near Toronto's waterfront doubles as a mission to avoid inhaling swarms of tiny flying insects known as midges.

Whether you're running errands outside, biking through a park, or just simply trying to enjoy some fresh air, chances are you've already had an up-close encounter (or possibly, even an accidental taste) of the pesky insects over the past few days.

Midges belong to the family known as Chironomidae, and emerge in large numbers every spring, typically starting in mid-April.

Although the tiny bugs don't pose any danger to us, their sheer volume during this time of the year makes them hard to ignore, especially since they have a knack for flying straight in your face, getting caught in your hair, and interrupting conversations in the most unpleasant way.

While the sudden midges takeover might feel random, it's actually part of their annual life cycle. The insects begin their lives underwater, feeding on organic matter and sediment, before rising to the surface all at once as adults and taking flight in massive swarms.

The annual phenomenon hits Toronto like clockwork, especially along the waterfront, and if social media is any indication, the initial wave has already arrived.

As annoying as they are, these tiny insects actually play an important role in Lake Ontario's ecosystem by serving as a key food source for fish, birds, and other aquatic creatures.

Most of the midges you see flying around are males, gathering in large groups as they wait for females to pass through so they can mate. It's a short-lived, but intense mating frenzy, and once it's over, their brief adult lives quickly come to an end, often leaving piles of dead bugs on balconies, sidewalks, and window ledges.

The good news is that their adult lifespan is short and only lasts a few days to a couple of weeks at most. The slightly less good news is that different species emerge at different times, meaning Toronto can see multiple waves of swarms throughout the spring, and sometimes even into late summer.

Rest assured that even though they might look like mosquitoes at first glance, these insects pose absolutely no danger to humans (besides serving as an unpleasant, unintended snack). If you're committed to avoiding them, your best bet is to keep your windows and doors closed, limit outdoor lighting at night, and steer clear of waterfront areas during peak swarming times, typically from mid-April to May.

If you live further from the waterfront, consider yourself lucky, because these insects typically tend to stick close to the water, meaning you're less likely to deal with their overwhelming, full-swarm effect.

Until their mating frenzy passes, your best defence might just be walking a little faster and getting used to breathing through your nose.
