Important Points and Resources on Emerald Ash Borer

Important Points!

  • EAB was detected in Peoria and Tazewell counties in 2014.
  • Once a county is added to the quarantine list additional sightings don't need to be reported. IL Dept of Ag would be flooded with these calls. The important find is the first one - after that assume all ash trees within that county need some type of attention.
  • Due to the volume of contacts, site visits will not be conducted by University of Illinois Extension.
