I may have found the cause of your problem Churak.
This picture was taken via my satellite spy cam early this morning outside your house. Looks like their hav'in a party. I can only imagine what they did last night on your pillow.
I think you need to keep your bedroom windows shut at night for safety. My dog interpreted some of their squirrel chatter and "barked" to me something about using a pine cone. It sounded very ruff ruff. He also mentioned the one on the left appears to be the leader. Be careful.
But yes, Surrey soap should do the trick. Good luck.
