The Most Dangerous Spiders In Canada That Will Soon Be Returning For Spring

We're not ready.

With spring time just around the corner, most of the country will soon be going under a massive melting period. The changing of seasons will be accompanied by the blossoming of trees and other plants, warmer temperatures, and the return of most animals that disappear during the cold months. But, it's not just the cute and furry creatures that will be returning. Spiders, too, make a comeback during the spring and summer months.

Yes, the creepy-crawly eight-legged arachnids may have been missing over the last few months, but warm temperatures will welcome the unwanted pests back into your life. In some cases, you might even start seeing them scurry around your home.

Of course, common house spiders aren't something to worry too much about, but what about the spiders that are actually dangerous? Even life-threatening? Well, look no further for a complete list of all the most dangerous spiders in Canada.

Some reports suggest that spiders are growing larger as climate change extends the warm season in Canada, so keep your eyes peeled!

Thankfully, the government of Canada has an enitre page dedicated to spiders and tips to keep them from entering your home. The page advises that "keeping your house clean reduces the number of pests, which are food sources for spiders. To prevent pests from entering your home, weather strip or caulk windows and doors, and repair screens."

TL;DR With spring about to return, many spiders species will also begin to become common across the country. Below is a list of the most dangerous spiders in Canada that you may come across.

Brown recluse spider

Probably one of the more common of dangerous spiders in the country, these tiny critters are known to have a seriously powerful bite. This spider's venon kills a small area of skin that can remain painful for several weeks.

Luckily, these spiders are quite shy and prefer staying out of the way of humans. They're commonly found in dark spaces and mostly in BC.

These spiders return to Canada from May to July.

Yellow sac spider

Native to California, Mexico, and parts of Central America, these spiders often end up across the border and living in Canada after catching a ride on grape imports.

Surprisingly, these spider bites are not that painful on impact and can feel similar to a wasp bite. Unfortunately, symptoms such as swelling and muscle pain can take weeks before going away.

Yellow sac spiders are known to hide in buildings and cars during the late spring and early fall when temperatures are cool.

Recall that last year, yellow sac spider sightings in government buildings forced workers to evacuate not once but twice.

Black widow spider

The black widow has to be one of the most well-known dangerous spiders in the world. Easy to identify thanks to their black, round body with two reddish triangles on their abdomen, these spiders usually arrive in Canada on grape shipments, as well — though they maybe be found "in southern regions along the Canada-United States border."

Surprisingly, many people who are bitten by these spiders show no symptoms of a poisonous bite, as the spiders likely won't inject any venom. When they do release venom during a bite, effects can include mild muscle pain that lasts over several days. The bites can turn fatal in extreme cases.

But this pest control service adds that "Black Widows are actually quite docile and will not attack humans unless provoked, even going so far as playing dead."

Female black window spiders often live up to 3 years.

Last year, several Black Widow Spiders were spotted in Canada.

Wolf spider

These critters are definitely the most terrifying on the list, but mostly harmless according to one Canadian pest control service. They're called "wolf" spiders as they don't spin webs to catch their prey, but instead chase them down like a wolf would attack prey. 

These spiders are native to Canada, chances are you've even seen them quite a few times if you have a cottage or go camping during the summer. Luckily, these spiders aren't that aggressive, and will only bite when they feel threatened. Their venom causes mild redness and swelling.

These spiders are often found hiding out in garages, basements, windows, and doors during winter months.

Though, the government adds, "wolf spiders are especially helpful to farmers and gardeners because they prey on common crop pests like caterpillars, plant bugs, and aphids."


Needless to say, it's time to start preparing to see these horrifying critters once again.
