I can speak to that a little bit. This is Erin from CKISS.
We've done some eDNA work here in British Columbia on invasive bullfrogs. At this point, eDNA is mostly a monitoring tool. It's used to measure the residual DNA that's left in the environment when a specific species inhabits that environment. You can take water samples and measure specific DNA patterns and assess it for the presence or absence of a species, but there's no known technique for treatment using that.
