Cattails and bulrush, both in the Typha genus, can be beneficial to an aquatic environment when carefully controlled. But given just a couple years of unmanaged growth, these plants will quickly cover the shallow water of an average-sized pond, often ringing the entire shore with stalks that can reach 10 feet high.
This type of takeover can create monocultures by pushing out other desired plant species, cause the formation of floating tussocks, harm the stability of the aquatic environment by reducing aeration and stifling the good bacteria, and hinder the aesthetic and recreational purposes of the pond or lake.
CattZilla is a pioneering adjuvant for chemical treatments of cattails, bulrush, and similar plants that grow in marshy areas. CattZilla will not kill anything but aids herbicides like glyphosate while also speeding degradation of the dead plant matter after herbicidal treatment. The degradation powers of CattZilla are especially helpful in knocking down cattail stalks that are standing up even after being killed.
This product has been tested extensively and proven to work in cattail management all over the country, having success from Florida to Wisconsin to Texas.

* This product is not for use in the State of Michigan. In California, Oregon and Washington use Cattzilla California. Cattzilla California is used 1 day to 1 week after aquatic herbicide treatment. Rules for application must be followed in each state. Some states will not allow the use of this product and others have special permits. Call us, 888.757.9577 for more information.
NOTE: CattZilla DOES NOT kill aquatic plants or algae


Lab Development

Over the past few years we have been experimenting at our facilities with different application methods of CattZilla and herbicides in cattail management plans. This is an ongoing experiment to optimize the effect CattZilla has on the dead matter of the plants. The progress will be updated periodically on our Natural Lakes blog.

Cattail Treatment


This neighborhood pond in Wisconsin was one of the first tests for CattZilla. Applicators added CattZilla to the herbicide in their mixing tank. Two months later the unsightly cattails were dead and had fallen over, ensuring that the dead stalks wouldn’t become an eyesore for the neighborhood.



A mixture containing a glyphosate herbicide and CattZilla was able to knock down the patches of cattails found all around this manufacturing plant’s cooling pond.


Overall, I believe through my visual observations that CattZilla provides more efficient capabilities of not only acting as a surfactant but also in relieving a pond owner of the unsightly dead cattail view at a much faster rate than normal.” – Zach, researcher and pond manager in WI

Dosage Rates

CattZilla works over a wide pH range, but for best results adjust tank mix to pH of 4 to 6.
Regular Dose:  (mixed with herbicide) 3 gallons per acre OR 8 ounces per 1,000 square feet
Super Dose: (mixed with herbicide) 15 gallons per acre OR 40 ounces per 1,000 square feet

Mix Rate: 16 oz per gal of herbicide solution

Q: Is this product hazardous?
A: No.

Q: How do you apply this product for cattail management?
A: Cattzilla can be mixed directly in the tank with the herbicide**.

Q: What pH should the mixing tank be at?
A: 4-6

Q: Can it be used alone?
A: Applications of Cattzilla alone may help to knock over dead standing cattail stalks.

Q: Does this product hurt fish?
A: CattZilla will only harm fish at 200-300 times the label rate.

**CALIFORNIA, OREGON, AND MICHIGAN APPLICATORS: apply algaecide first, then return and add CattZilla
