What can we do to remove owls from our warehouse?

We have had owls move in to replace the pigeons which we thought was a real pain, but the owls are leaving even a bigger mess. They are damaging product with their droppings and it is every where. We need to keep cleaning it up after them, but as I said the mess is far bigger than the pigeons.
So what can we do to have them removed and relocated?
