Zequanox®
Effective and Environmentally Safe Control of Zebra and Quagga Mussels
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.

Zequanox for recreational and environmental rehabilitation in:
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

The Future: Great Lakes Could be Altered by an Invasive Species
Quagga mussels, an invasive species, are widespread across Ontario, Quebec, and Manitoba. Victoria Fenn Alvarado explores their impact on the Great Lakes.
Invasive Mussel Collaborative: Good Harbor Reef Project
Mussels invaded the Great Lakes in the 1980s, arriving via ballast water. They form dense colonies, clogging pipes and damaging infrastructure.
Invasive Mussels?
Responding to the first sign of them can prevent serious damage and permanent establishment. Treat the effected areas with Zequanox ASAP.
If discovered at the veliger stage you can treat with a low dosage or at adult stage with a higher dosage both for approximately only 6 hours.
Approved for drinking water and water treatment facilities.
