What Does It Mean When a Species is Listed as Injurious
Wildlife?
Species listed as injurious (including their gametes and
viable eggs) may not be imported into the United States
or transported between the continental United States,
the District of Columbia, Hawaii, the Commonwealth of
Puerto Rico or any territory or possession of the United
States by any means without a permit issued by the
Service.
It later goes on to talk about animals use within a state is up to the state.
I hope that's the right bit of info.
