August is Tree Check Month! 🌳🔍

Take 10 minutes to walk around your yard and look at your trees for signs of the Asian longhorned beetle. This destructive invasive pest threatens our maples, birches, willows, and other favorite trees. Look for round exit holes (about the size of a dime), shallow divots in the bark, where the beetle lays its egg (may weep sap), sawdust‑like shavings on the ground or around tree bases, the beetle itself (shiny black with white spots and long antennae). If you see something unusual, report it right away to your state plant health officials. You can help protect America’s trees!

Tree Check Month is a great reminder to check your trees for invasive pests and damage. The Spotted Lanternfly lays its eggs on trees and other hard surfaces; most egg masses appear to be a tan/brown color once dried, and older masses will appear gray. Report any life stage to clemson.edu/invasives.

Spotted lanternflies, accidentally introduced to the U.S. in 2014, are munching their way through the Northeast and Midwest. These invasive insects pose a serious threat to farmers' crops and the w**e industry, potentially costing some state economies over half a billion dollars. While some people are still squashing them on sight, others are turning to a more unexpected ally to help stop the spread.

Tree Check Month is designed to combat the activity of woody invasive pests in the late summer. However, the Spotted Lanternfly life cycle overlaps during this time. Adult and instar spotting can occur. For more identification, life cycle information and reporting, visit our website at clemson.edu/invasives.
