Alert Issued in Washington After Zebra Mussels Discovered at Renton Pet Store

The recent discovery of zebra mussels on Marimo moss balls in Renton, Washington has raised concerns among wildlife officials and pet store owners alike. Zebra mussels are highly invasive mollusks native to Eastern Europe and western Russia, known for their rapid reproduction rate and ability to clog pipes and other intakes. The Washington State Department of Fish and Wildlife (WDFW) is urging pet stores and aquarium owners to be vigilant and report any sightings of zebra mussels immediately.

The incident in Renton occurred when a local wholesale aquarium company found zebra mussels on a shipment of Marimo moss balls. Upon notification, the WDFW Aquatic Invasive Species team quickly responded, collected the contaminated moss balls, and confirmed the presence of multiple adult zebra mussels. This discovery highlights the importance of early detection and prevention efforts to stop the spread of invasive species.

Zebra mussels were first detected on Marimo moss balls in retail pet stores in Seattle back in 2021, leading to an international response as contaminated moss balls were found in 41 states and nine Canadian provinces. The potential impact of zebra mussels in Washington is significant, with officials estimating a cost of over $100 million annually to maintain the state’s power and water facilities if the mussels become established.

Justin Bush, aquatic invasive species policy coordinator, emphasized the role that individuals can play in preventing the spread of invasive species. He encouraged aquarium owners to use online reporting options such as the Washington Invasives app or online reporting form to report any potential sightings of zebra mussels. By being aware and proactive, individuals can help protect the economy and environment from the devastating effects of invasive species.

In addition to zebra mussels, another invasive species of concern in the Pacific Northwest is a small beetle capable of wiping out entire species of trees. Officials are warning the public to be on the lookout for this beetle, which poses a significant threat to the region’s forests.

By working together to identify and address these threats, we can help protect our environment and prevent costly damage to infrastructure and native species.
