Talking about spiders probably isn’t the most popular topic with people who have arachnophobia or fear of these eight-legged creatures. However, they are beneficial for the environment because they get rid of pests and insects. You may not associate Minnesota with spiders, but the state has quite a few, over 500 to be exact.

You can put spiders into two main groups, web-building and hunting. There are seven species of poisonous spiders in Minnesota among them. Of course, spiders, like many animals, can sometimes find their way outside of their range, a term scientists call vagrants. We’ll cover some of the most common and unusual species of the state.
