Zequanox Overview

Using the Power of Nature to Control Invasive Zebra and Quagga Mussels

A scientific breakthrough, Zequanox® is a highly effective, environmentally compatible solution for controlling invasive zebra and quagga mussels (Dreissena species), with measured mortality rates greater than 90% in targeted colonies. Zequanox is proven effective in a broad range of water conditions and temperatures, and it can be used to control mussels at all stages of maturity—from veliger to adult.

The onset of mussel mortality typically occurs within a few days of the treatment day, but ongoing mortality can be observed for several weeks thereafter, with the timing of peak mortality varying based on mussel activity and water temperature.

Zequanox …Simple and Flexible

A biological solution, Zequanox is simple to administer and offers unmatched application flexibility. Compared to traditional solutions Zequanox offers a number of advantages:

  • Treatments can occur during the workday and can be completed within hours—without having to schedule downtime.
  • Can be used as a control agent for mussel in all life stages.
  • Effective in broad range of water temperatures.
  • Applies with standard injection equipment.
  • Applicators need only minimal personal protective equipment.
  • Detoxification is NOT required before discharge.
  • Zequanox is noncorrosive and nonvolatile.
  • Constant equipment maintenance is NOT required to ensure efficacy.

When you choose Zequanox, you benefit from its ease of use and effective control of mussel populations, without incurring the risks commonly associated with harsh chemicals or the additional operating costs of maintaining mechanical solutions.

How Does it Work?

Derived from a naturally occurring microbe (Pseudomonas fluorescens), Zequanox is highly selective and has been proven to be lethal to zebra and quagga mussels, without harming humans, infrastructure, nontarget species, or the environment. The product, composed of dead cells, is recognized by the mussels as a nonthreatening food source and is readily consumed. Once ingested, Zequanox destroys the mussel’s digestive system.
