Hello Sherry,
Michigan has experienced large numbers of boxelder bugs in recent years. They are more prevalent when the previous summer is dry and the next year's spring is very wet. They feed on flowers and female boxelder tree seed pods. They are mostly nuisance pests as they don't do much damage to trees, wood, cloth, and food products. The following article from MSU contains some important information about boxelder bugs. (Boisea trivittata). https://www.canr.msu.edu/resources/boxelder-bug

Since boxelder management depends on correct timing, it's important to understand what to use and when to apply specific control measures.  The following article from the University of Minnesota Extension explains boxelder bugs and the variety of measures to control them.
