Firewood Pests and Diseases

  • Emerald ash borer is a non-native insect that has killed millions of ash trees since 2002 when it was accidentally introduced into Michigan from China. This invasive insect is spreading to other states and Canadian provinces due to the movement of infested firewood and nursery stock. Emerald ash borer has been found in Minnesota and firewood could further spread this destructive pest across the state.
  • Spongy moth is among America’s most destructive tree pests. The moths have caused millions of dollars of damage to forests in eastern states and now threaten Minnesota forests. Spongy moth eggs can be transported on firewood.
  • Oak wilt is a disease that kills large numbers of oak trees in Minnesota every year. Oak wilt can be spread by insects that carry the fungal spores from infected firewood to healthy trees.
  • Dutch elm disease has devastated our elm population and continues to kill more elms every year. It can be spread when insects carrying the fungal spores travel from infected firewood to healthy trees.
  • The Asian longhorned beetle, a threat to hardwood trees (e.g., maples, birch, elm and ash), has been detected and quarantined in New York, New Jersey and Ontario, where eradication efforts are underway. It was also detected in Illinois but was eradicated.
