Thank you for your reply.
Unfortunately the monkeys are protected, so getting rid of them is a problem. I know they are petrified of guns with red lasers, so I will have a toy gun with a red laser left in the unit to scare them. The one monkey stole my toast out my hand as I was eating breakfast, so I understand.
There used to be a stairwell down to the ocean from cascades, but thieves were using it to housebreak, so they closed it. As usual they spoil it for all of us.
