North Carolina is releasing wasps to fight an invasive beetle in ash trees.
Forestry officials say the particular species of wasp is a natural enemy of the emerald ash borer. The beetle was first found in North Carolina earlier this year. It invades ash trees and kills them in two to three years.
Kelly Oten of the North Carolina Forest Service released 900 wasps, which naturally do not have stingers, Thursday morning. She says the USDA is breeding them.
"They lay eggs in the larvae of the beetles and basically eat it from the inside out," Oten says.
