Robin Problem

We have had a robin problem for more than a week. There are a pair of robins determine on building a nest on top of our garage door opener. They wait until they see the door open and have been inside as we get the car backed out. That is how I noticed her first. There were sticks and etc. on top of the opener and it was the first time the door had been open that day. Pop has blown off the nesting materials numerous times. We keep the door shut most of the time. They poke around the yard awaiting their chance to get in. I would think they would soon be needing their nest and would have another spot picked. I don't know how to suggest a different nesting site!_________________________________ Update---Pop put a plastic owl up beside the nesting area. Didn't scare Mrs. Robin one bit! She was up beside/ under the owl before it even cooled off from Pop's hands!!! Now going to try oil and screen.
