Are Marimo Moss Balls Still Banned? What 2025 Buyers Need to Know
Are marimo moss balls still banned? It’s one of the most common questions we get, and for good reason. Following the zebra mussel outbreak in 2021, strict import regulations created confusion across the industry.
At Moss Amigos, we provide clarity, compliance, and confidence. As a fully certified California nursery (CDFA #C3443.001) with Phytosanitary Certificate No. S-C-06085-12649862-CA, our moss balls are 100% zebra mussel–free, pest-free, and legally distributed nationwide.
Backed by over 25,000+ verified customers and an industry-leading compliance record, our company is the trusted partner for hobbyists, wholesalers, and shop owners who want quality without the environmental risk.
Wait, Why Were Marimo Moss Balls Banned in the First Place?
In early 2021, the U.S. Geological Survey and U.S. Fish & Wildlife Service discovered invasive zebra mussels hidden inside marimo moss balls sold at pet stores in over 21 states. These mussels spread rapidly in freshwater systems, clogging infrastructure and destroying native aquatic ecosystems. In response, federal and state authorities launched a nationwide investigation and implemented emergency import bans to stop further ecological damage.

In short, no. They’re not banned across the board. However, the ban still applies to non-compliant, unverified moss ball imports. The good news? You can still legally buy certified, pest-free marimo moss balls from registered nurseries that meet all state and federal guidelines.
