The three most poisonous species of spider in Ontario are the black widow, the yellow sac and the brown recluse.
Black widow spiders
Black widows are actually rare in Ontario but they are by far the most toxic and bites from any one of the five species that exist in our province can result in hospitalization and will even be fatal in 1% of cases. The most recent reported cases of black widow sightings in the last few years occurred in Port Hope, Oakville, Mississauga and Bolton.
Black widow venom is a neurotoxin that can almost instantaneously affect the nervous system, causing victims to sweat profusely and experience raised blood pressure, fever and blurred vision.
Most bites occur while people are out working in their back yards as they garden or remove the piles of firewood and brush that black widow spiders like to nest in. They also like secluded garages, basements, crawl spaces and other areas where they are generally left undisturbed.
How to identify a black widow spider
They are small, shiny black in colour with red markings shaped like an hourglass on the underside of their abdomen. An adult black widow only measures about the size of a paper clip.
This species of pale yellow spider is notable for its darker coloured fangs and cocoon-like webs. In southern Ontario they like to spend the warmer spring and summer months nesting in and around porches and decks and then migrate inside during the winter months. They are nocturnal creatures, coming out to hunt for insect food at night. Their bite is very painful and can cause swelling and blistering.
This spider can easily be identified by the violin-shaped markings on its thorax – hence its nickname ‘fiddleback’. It doesn’t actually live in Ontario but is occasionally transported in from warmer southern climes in shipped-in goods such as fruit and vegetable containers.
Brown recluse bites cause intense pain, fever, swelling, blistering and necrosis – ie, they can make your flesh rot. Although not usually fatal, brown recluse bites can take up to two months to heal and are extremely painful.

All this being said, most of Ontario spiders do not pose a huge danger to people and are actually beneficial, playing a vital role in the ecology by eating other insect pests and helping to pollinate plants and trees. They are also an important source of food for other wildlife such as birds, small mammals and fish.
Interesting spider facts
- Spiders are part of the Arachnid family which is comprised of more than 30,000 species.
- Most spider species have either six or eight eyes.
- However, despite their large number of eyes, many spiders are short sighted. They rely on their hairy bodies to sense when predators lurk nearby and to feel their way around.
- Not every species of spider spins webs. Only those that have spinnerets (specialized spinning glands located at the end of the abdomen) can spin webs.
- Spiders often replace their webs on a daily basis – or whenever they get torn or dirty. They recycle the old web silk by rolling it into a ball and eating it!
- Most spider species have fangs through which they eject their venom.
- They are oviparous – ie egg laying creatures.
- Spiders are not insects. They have 2 body parts (the thorax and the abdomen) and 8 legs, compared to the 3 body parts and 6 legs of insects.
- Females are usually larger than males.
- Sometimes spiders are confused with opiliones (also known as harvestmen, harvest spiders or shepherd spiders) which are harmless to mankind, have no venom, fangs or spinning glands and are often seen during the summer harvest (hence the name).
- Fear of spiders (Arachnophobia) is one of the most widespread animal phobias in humans.
