Also, accumulated pigeon excrement signals to pigeons "this is a safe
place". So cleaning helps to deter nesting.
Politically incorrect message follows:
However, I've had the most success leaving a dead pigeon where they want
to roost. Of course there is some short term olfactory nuisance, but it
worked for years afterward.
I'll leave it to the reader to find a dead pigeon, but it is amazing how
accurate a scoped air rifle can be at 100'. YMMV and firearms laws
usually apply. Of course, falcons are the "correct" (and considerably
more expensive) way to dispose of live pigeons, but the result is the
same in either case.
