How to Disable /cPanel and /whm and /webmail

I just want to disable:
example.com/cPanel
example.com/whm
example.com/webmail
Basically I am looking at any external direct access to hosting account. This is for SEO purpose as I don't want Google bots to directly land up on this since I am using another IP at the front end which is different from the actual server IP.

There is a host control option in whm and with that you can disable all the above.

Edit: But Googlebots can still land up on those pages as they still show a no access page on those URLs. I think you may need to do template edits.
