The pollen are carried for great distances (DOWNWIND!),
but again, if planted in isolation the problem is really
non-existent.  A female about four blocks off-campus here
NEVER sets seeds.  The only male in the area that I know
of is a new specimen on our campus, so four blocks with
some big academic buildings in-between does not result in

Even if the female IS pollinated, you can eliminate the
problem by picking up the seeds as they fall.  The fleshy
arils don't really stink until they have been on the
ground for least in my limited experience.
