Unlike other pests, spiders do not spread diseases; however, if provoked, they bite. The venom of some of these spiders are highly toxic and can cause deadly consequences. Canada is a home to some of the most deadly spiders in the world. Here is a list of a couple of deadliest spiders found in this region:

1. Black Widow

These spiders are mostly found in the areas near to southern Canada and the USA border. These spiders are highly venomous and their venom is considered 15 times stronger than the venom of a rattlesnake. The black widow spider can be recognized by its round black abdomen with a striking red stripe. The spider is smaller in size. It comes in two varieties- one with a red stripe and the other is completely black. These spiders only bite human beings when provoked. The bite of the female black widow is considered deadly than the male and is a threat to human health. However, this doesn’t result in deaths. The bite feels like a pinprick and pain is felt after a few minutes. It spreads rapidly to other parts of the body and causes nausea, abdominal pain, hypertension, and paralysis of the diaphragm resulting in breathing difficulties.

2. Brown Recluse

The Brown Recluse is also known as fiddle-back spider and violin spider. These spiders bite humans when they feel threatened. These spiders can be found in homes and usually build their web in old furniture and boxes. The bites are often painless and that is why it goes unnoticed. However, the effect shows up after a few hours. The area where the spider bites, turns red. The person experiences fever, itching, convulsion, nausea and intense muscular pain. In extreme cases, a brown recluse spider bite can even cause necrosis. In other words, it eats up the flesh and can result in a condition called Loxoscelism. In this case, painful wounds will appear in the area which won’t heal quickly. The wound gradually turns purple and can be life threatening. There is no treatment for the bites and wounds can take months to heal completely.

3. Hobo Spider

Though the effect of its venom on human beings is widely debated but, when tested on lab rats, it was found that the spider venom resulted in necrosis. The bites can cause open wounds that take a long time to heal. This spider is known to be very aggressive and is one of the most common house spiders.
