Assisting People with Delusional Infestation (DI)

  • Dirty hands
  • close up of an insect on a leaf

UNH Extension, in partnership with health care professionals, is developing this resource to help pesticide applicators, health care workers, educators and others who may encounter patients and clients who suffer from a delusional infestation disorder.   Over time, we will update this webpage with resources and updates to provide research-based best practices on this issue.
