Controlling Cattails in a Pond with Nesting Ducks

By July, ducklings are on the water, so herbicide treatment won’t disturb nesting. Two aquatic herbicides control cattails:

• Glyphosate (Rodeo, Eraser-AQ)
• Diquat (Reward, Weedtrine)

Non-Chemical Option

Repeatedly clip stems at or below water level to starve the roots. Effective for small patches if you don’t mind getting muddy.

Always follow label directions for aquatic herbicides.
