Thanks for all the good suggestions. Appreciate it.
For now I'm going with Bobbex spray, comb of galic etc, supposed to stick the best and a Guardian ultasonic sound/ strobe that covers 5000sq ft. I was told they get used to the spray odors so you need to switch out the sprays every few months to be affective.
Will let you know how they work.
If none of it works I will offer you my bowhunting pest removal services for free.....
