From what we have researched, these appear to be a wasp spider, however not native to MN. Any thoughts about what may have attracted them? They are in the hundreds at the back of several yards in our neighborhood and are causing some consternation. We would also appreciate advice on what to use to at least reduce numbers. Thank you!!!

Don't worry about reducing the number. These spiders are doing you a favor by catching other insects. Your spider is a banded argiope. It is harmless and quite common. You will find it on our spiders page under common orb weaver spiders. It is also called a garden spider. https://extension.umn.edu/insect-relatives/spiders#web-building-spiders-52360
