Barnacle Stop®/Mussel Stopper
Barnacle Stop®/Mussel Stopper is an EPA registered pesticide, 89825-1. Although it is a registered pesticide, it doesn’t kill anything. It prevents Barnacles, Zebra Mussels and Quagga Mussels from attaching to underwater surfaces. Although these three organisms are quite different they have something in common that allows Barnacle Stop®/Mussel Stopper to work. The mussels attach themselves using a proteinaceous extrusion called the Byssal Thread. Barnacle Stop®/Mussel Stopper prevents the Byssal Thread from attaching.
Barnacle Stop®/Mussel Stopper is made from a patented (10,053,584) blend of pharmaceutical grade Capsaicin, which is in wax form. It is carefully blended with natural waxes in an industrial size steam kettle. When thoroughly blended, the molten product is cast in the applicator, bars and tubs. Tests by Mote Marine Laboratory show that Barnacle Stop®/Mussel Stopper is essentially insoluble in water. That is why it can be applied UNDERWATER like a crayon. That is also why it stays put on the underwater surfaces.
