Illinois is joining several Midwest states in lifting an internal quarantine of the Emerald Ash Borer. It is an invasive beetle native to Asia that has been destroying ash trees around the state.
Restriction of firewood movement helped contain the pest, but the number of affected Illinois counties still increased.
Scott Schirmer is the Plant and Pesticide Specialist Supervisor for the Illinois Department of Agriculture. He says discovery of the beetle in 10 new counties led to the decision.
