So you did the work and excluded those pigeons but wait they are still hanging out. Annoying? Yes it is.
Sometimes they just won’t move and the second part of the battle begins. May I suggest a tube of PIGNX, designed to get on their feet and they won’t like it much.
I think of it similar to when we get Super Glue on our fingers, that stuff won’t come off and it is very annoying. Isn’t it?
