Yes like most rhizome type plants, bamboo, bindweed, knotweed they are all the same, easy to deal with in small outbreaks and capable of some dormancy then again sudden bursts.
Unfortunately by the time your aware its normally too late, your into medium infestation and the only way to deal with them is constant knock back and treatment.
If they originate from outside your boundary you have no chance your down to treating the symptom and not the cause.
