KMVTBOISE, Idaho (AP) — The invasive quagga and zebra mussels have a $100,000 bounty on their “heads.”

The U.S. government is offering the six-figure prize for the best suggestion on how to stop their relentless and destructive spread because scientists say they are stumped.

“We might as well give it a try,” said Sherri Pucherelli, a biologist with the U.S. Bureau of Reclamation. “Open water. That’s really where the challenge is. Nothing has been developed right now that causes complete eradication in a large water body.”
