CLEAN, DRAIN AND DRY
Zebra and quagga mussels can survive out of water for up to two weeks. AIS, such as zebra
mussels, are invisible to the naked eye during the larval stage and
can be spread through drops of water that live up to 27 days in cooler
temperatures. Aquatic plants can be spread by tiny fragments as well.
After boating and before launching your boat in a different water body:
• Rinse boat and all equipment with hot tap water ideally more than
140 degrees F to kill zebra and quagga mussels.
• Spray boat, live well, engine and trailer with a high-pressure sprayer;
• Pull plugs from bilge, live wells and engine
to drain upon leaving a water body.
• If washing the boat away from the water
body you are leaving, do not allow runoff to
enter a drainage. Control your runoff.
• Dry boat and all equipment for at least five
days. Use a towel to speed up the drying process.
• Visit stopaquatichitchhikers.org for more information on procedures and AIS on
watercraft.
