Canada’s waters are under threat from aquatic plants, fish and invertebrates including Eurasian Water-milfoil, Purple Loosestrife and Zebra Mussels, which are not native to our country. These species have no natural predators, and can often reproduce quickly. They can rapidly take over waterways and wetlands, and can be seriously harmful to Canada’s wildlife and habitats. 

Boaters can play a huge role in the spread of invasive species. Plants and wildlife can easily become stuck on boats and equipment, and can easily be spread if your boat is moved to a new waterway. It’s important for boaters to make sure they clean their boat and equipment thoroughly before moving to a new waterway. 

Use one (or all) of the following methods to clean your boat of invading species: 

• Rinse with hot tap water (at least 40° C)
• Spray with high pressure water (250 pounds per square inch)
• Dry your boat and equipment before moving to another body of water

Always inspect your boat, trailer, and equipment and remove any visible plants or animals. Remember, some species can survive outside of the water, so if you need to drain water from your boat’s motor, live wells, bilge, or transom wells do so on land away from any water source.
