Most people know about summer allergies thanks to pesky pollen and weeds. But we regret to inform you that fall allergies in Canada are a thing. Here's everything you need to know about it.

According to The Weather Network, the main fall allergens are ragweed, mold and dust mites. However, these are probably not the first things that come to mind when you think about fall. 

Instead, it's usually the leaves changing colours, Thanksgiving, pumpkin spice lattes and Halloween that are on your mind. But it would be worth it to keep allergies at the forefront during the season. Especially since these environmental allergies can last way past spring and summer in Canada.

"Grass, tree and ragweed pollens, molds, dust mites, and cats and dogs [affect Canadians the most]," Harold Kim, president of the Canadian Society of Allergy and Clinical Immunology told The Weather Network.

In fact, because ragweed blooms late in the year, it is one of the most prolific fall allergens in Ontario, Quebec and the Maritimes.

While ragweed is the biggest concern it's not the only risk. If warm temperatures persist through the end of summer and into fall, dust mites could have a big impact on allergy sufferers as it thrives in warm and humid places.

Yet another allergy risk is mold, which develops in damp environments like fallen leaves and it could make for less than pleasant walks in the woods in the fall.  

While these allergens pose a risk all across the country, in B.C. and the prairie provinces specifically, grass pollen is also a prominent allergen until the end of September.

Fortunately, there are steps you can take to avoid a miserable fall. The Weather Network suggests washing your hands, monitoring local pollen counts, using dehumidifiers and routinely cleaning air filters and fabrics to limit the effect ragweed, mold, and dust mites have on you in the upcoming season. 

So, if you're prone to allergies you might want to think twice before jumping into that pile of leaves.
