Become an Early Detector
How to Become an Early Detector:
  1. View the training slideshows below: Learn how to scout for emerald ash borer, Asian longhorned beetle, and thousand cankers disease of walnut.
  2. Choose an area in your community to survey: Search for damage by these pests on trees in your yard, lining the streets in your town, or in public parks.
  3. Report your findings​: Even if you don't see damage, please report where you've been searching for these tree killers.

Early detection of new invasive pest infestations is important. It decreases the damage pests cause and can make controlling them easier.


By becoming an early detector of forest pests in Indiana, you increase the chances of detecting new infestations before they destroy your community's trees.
