Black Widow Spider
With more than two thousand hospital visits annually for black widow bites in the US, I’d say humans definitely need to be cautious of this spider. You can find them among vegetation or woodpiles. Thankfully, the invention of the widow spider antivenom has prevented deaths. Though, getting care is crucial because their venom is speculated to be fifteen times stronger than the rattlesnake’s venom! Again, they pose the most lethal danger to children, sick and elderly people.
Wolf Spider
Although not fatal, it is crucial to seek medical attention if bitten by the wolf spider. They inject their venom when threatened. There are over 125 species of the wold spider in the United States alone and about fifty in Europe. Just their hairy appearance and strange eyes alone are enough to send me to the hospital! Unsurprisingly, they got their name from an early belief about the wolf-like way they hunt for prey in groups. Actually, since they are busy hunting for food, they are not known to spin webs.
