Dear Valued PetSmart® Customer,

Zebra mussels are regarded as one of the most destructive invasive species in North America. They can quickly take over once they get established in a waterbody and cause significant damage including disrupting the food chain, changing the chemistry of the water and clogging water intake and delivery systems. The concern is that live mussels released into a storm drain or flushed could be introduced into a waterway.

If you have an impacted moss ball product at home, please bring it back to your local PetSmart store for a full refund, and we will dispose of it safely and responsibly.

If you are not able to return the product to the store, we strongly recommend following the instructions outlined by the U.S. Fish and Wildlife Service for proper disposal and aquarium sanitation. The U.S. Fish and Wildlife Service website can be found here.

Our top priority is supporting the health and wellness of people, pets and our ecosystem. For any questions about this withdrawal, please contact our Customer Care team at 888-839-9638 between the hours of 8 a.m. and 9 p.m. EST.
