This aquatic species clogs waterways and is considered ecologically invasive over most of N. America. Its sale and transportation have been prohibited in 8 states.

It is obvious from its current distribution that it is much hardier than indicated above. Naturalized populations have been reported in all lower 48 states except South Carolina, and in at least 7 Canadian provinces.

It is native to much of Asia and Africa.

It is easily spread on boat hulls and other recreational equipment.
