Our Ladybugs

​​​​​​​39154326922_130d5ec646_b.jpg​The heather ladybugs are beneficial insects in our campus. They help us control the population of scale insects and other pests which voraciously feed on our plants, and help us encourage others to use native predators as a sustainable practice for pest control.​
