MINNEAPOLIS, Minn. (KARE) - A group of Minnesota third graders got a unique science lesson at a special Earth Day event at the Mall of America.

On Monday, 72,000 ladybugs were released inside of the mall, and Visitation School's Sheriya Wentzlaff was there to see it.

"Before I got to hold these lady bugs, I was pretty scared of them," she said. "I overcame my fear and helped the lady bugs."

The bugs take the place of pesticides. The red and black insects are brought in to combat pests like aphids that would otherwise eat away at the mall's tropical plants.

"Ladybugs are what I like to call, sort of a biological defense system," said MOA's Senior Manager of Environmental Services Lydell Newby.
