Idaho Targets Quagga Mussels with New Copper Treatments | Boise News

Idaho’s fight against invasive quagga mussels in the Snake River just got a major upgrade—this September, crews are deploying a targeted copper-based chemical treatment from floating barges to reach mussel havens up to 30 feet deep. After four years of battling these invaders, officials are refining their strategy with a new combo: EarthTec QZ for the first 72 hours, followed by Natrix, plus granular treatments in mesh bags near colonies. While the chemicals can harm fish—a known trade-off—they’re seen as essential to prevent catastrophic damage downstream, especially to salmon and steelhead. Scuba divers are already reporting dead adult mussels, a hopeful sign the treatment is working. With each year’s adjustments, Idaho remains laser-focused on protecting its river ecosystem from these destructive invaders.
