New applications of forensic entomology include urban entomology, used in civil actions relating to insects and human-built structures, and stored product entomology, used in civil actions related to insect infestations of products such as food.
Forensic engineers determined that a design flaw and construction modifications caused the collapse of a wall at an upstate New York sewage plant which caused a release of nearly 600,000 gallons of wastewater to spill into a creek feeding the Susquehanna River.

An average of three people in North America die in attacks by black bears or grizzlies each year. Researchers collect hair and scat samples for DNA analysis for grizzly research and to identify bears that have been involved in an attack.
Connecticut Governor Dannel Malloy appointed a 17-member panel of experts and legislative leaders to develop a plan to address the problems of the state crime lab in Meriden. The lab recently failed two federal audits leaving it unable to upload DNA profiles to the national DNA databank and lost its national accreditation.
