My vinyl outdoor window blinds are fasten to the siding with plastic screws.
After a heavy wind the other night, one of the blinds was blown off because the
heads of the plastic screws snapped. I need to remove the headless plastic screws.

I have a screw extractor that I could use. Also, since the screws are plastic,
I could just drill them out. Any ideas on the best approach to extract the screws?
