A method for controlling zebra mussels in ship ballast tanks comprising treating ballast water which contains zebra mussels or which is prone to zebra mussel infestation with an effective amount of a water-soluble dialkyl diallyl quaternary ammonium polymer (polyquat). A preferred polymer is a poly(quaternary ammonium) compound having the recurring structure [DMDAAX-] resulting from the polymerization of monomeric dimethyl diallyl ammonium X-, wherein X- is any suitable anion.
