Which Spiders in Canada Are Poisonous?
WouterWhile most spiders are harmless, there are a few types that are harmful. A few spider species are known to bite humans and have been found in Canada. Depending on the species, a bite can be painful and sometimes life-threatening. Some species are more common than others. If you’re afraid of being bitten, it’s best to avoid the area where these creatures are likely to live.
If you’re concerned about being bitten by a spider, it’s a good idea to wear gloves and protective clothing. You’ll also want to avoid areas where the spider’s web is likely to be. Especially in secluded locations, you’ll want to be cautious.
Wolf spiders are medium-sized brown spiders that inhabit grasslands and woodlands. They don’t spin their own webs, but instead are found chasing down their prey. While the venom they produce isn’t dangerous, it can cause mild swelling.
Another poisonous spider found in Canada is the black widow. Females have a distinctive red hourglass marking on the underside of their shiny black abdomen. These spiders can be found in southern Ontario. They are not very common in the Canadian home, and if they do find you, they rarely bite. However, they can travel outside their range by eating fruits and vegetables.
Funnel web weavers are another type of spider. These are native to Nova Scotia and can be a source of severe reactions to their bites. Their webs can cause painful and uncomfortable soreness and a slow healing process.
