Search engine listing deleted file

Hallo everyone
I’m making a lot of rookie mistakes and my latest one is that I made a copy of my site at a “staging” file in my public_html file and recently deleted it after it broke, but now I find that Google is listing it, now I know that I can redirect it in the .htaccess file but my question is:
Is it possible to write a code that will just redirect all URL to the corresponding live URL?
I mean like mysite.com/home instead of mysite.com/staging/home
So it will just ignore the “staging/” part?
Thanks ahead
