An invasive zebra mussel that poses a serious threat to Wyoming’s natural resources and water systems has been found in moss balls, a product sold at many aquarium and pet supply stores. If you have a moss ball, we need your help to stop zebra mussels. All moss balls are impacted.
Never pour aquarium water or plants or release unwanted pets into any natural waters.
Dispose of any moss balls you have using the Game and Fish step-by-step guide.
Do not flush or pour water down drains if it's been in contact with moss balls.
Do not buy new moss balls to add to your tank.
Once zebra mussels become established in reservoirs, lakes or even city water systems, they wreak havoc. They remove nutrients from water, clog pipes and waterways, damage boats and out-compete native mussels. Further, in many cases, zebra mussels are impossible to remove and could have costly impacts for Wyoming.
THANK YOU FOR HELPING TO STOP THE SPREAD OF ZEBRA MUSSELS TO OUR WYOMING WATERS.
IF YOU HAVE A MOSS BALL
Please follow these steps to keep Wyoming’s waters free of zebra mussels.
Remove any pets from the water and tank.
Remove the moss ball, other plants and any water from the aquarium and put them into a heat-safe pot. Do not dispose of any water down the drain or toilet.
Inspect the moss ball and tank for zebra mussels and if you find any contact your local Game and Fish regional office.
Boil the moss balls, plants and any water it’s been in contact with at least five minutes
Dispose of the moss ball and other plants in trash.
Pour out the boiled water on a semi-permeable surface. That could be a houseplant or outside — like grass or soil — that is not located near standing water or a storm drain.
