Zequanox
Zequanox® Controls Invasive Zebra Mussels and Quagga Mussels Without the Use of Harmful Chemicals
Since the 1980s, the question of how to get rid of zebra mussels and quagga mussels in a way that is safe for other aquatic life has been an important topic in our water systems. Zequanox molluscicide is the industry’s only selective and environmentally compatible control of invasive zebra and quagga mussels (Dreissena spp.) at all life stages — from veliger (larva) to adult. The product delivers efficacy comparable to chemical solutions, but does not endanger employees, damage equipment, or result in harmful impacts to the environment or other aquatic organisms when used as directed.

Open Water Systems
- Lakes, reservoirs, ponds
- Rivers and streams
- Marinas
- Docks, piers, swimming platforms, submerged infrastructure, buoys
- Watercrafts
- Ballast water
- Shorelines and beaches
- Other open water systems
As zebra or quagga mussels colonize open water bodies, they disrupt the natural ecosystem by impacting the filtering behavior of native freshwater mussels, causing the proliferation of toxic blue-green algae, decreasing game fish populations, and causing risk or injury to swimmers from sharp shells. In addition, these invasive species block water intakes, damage boats and other recreational equipment, and decrease lakefront property value.
Zequanox for open water systems:
- Highly effective rapid response tool to prevent against large-scale zebra or quagga mussel infestations
- Highly selective with no significant effect on water quality or non-target organisms
- USDA certified as BioPreferred and Biobased – biodegradable, not persisting in the environment
- Minimal regulatory restrictions when compared to chemical alternatives
- Non-corrosive – no risk to boats or recreational equipment
- Zero-hour re-entry interval (REI), so water can be used continuously for recreational purposes
