Spotted lanternflies, originally from Asia , have been spreading across parts of the U.S. Virginia Tech researchers have found a new way to use ants to detect invasive insects.

Ants that foraged in areas with spotted lanternflies carried traces of the bugs' DNA in their bodies.

The researchers are developing a field-ready antDNA kit that allows analysis to be done faster and faster.
