LAWRENCE COUNTY, Ohio (WSAZ) -- If you've driven through southern Ohio lately and wondered about those purple boxes hanging in the trees,well, mystery solved!
They're insect traps, specifically for a pest called the emerald ash borer. The Ohio Department of Agriculture has 75 hundred of the purple traps scattered all across the state. Once the insects infest an ash tree, it dies within five years. That represents a significant threat to Ohio's 5 billion ash trees.
The bugs come from Asia and were first discovered in Michigan in 2002. Since then they've continued to spread south. The state placed the traps where the bug has not yet been sighted. Emerald ash borers are attracted to the color purple.
Experts say the bug is often spread through firewood and say it's best if campers buy their wood locally and not haul it from place to place.
