If you want to disable wget to grab your site pages then simply add the code below
in the .htaccess file under public_html directory for which you wish to disable the wget grabbing.
SetEnvIfNoCase User-Agent “^Wget” bad_bot
<Limit GET POST>
Allow from all
Deny from env=bad_bot
Now, if anybody tries to grab info from your website using wget, he will receive a 403 error.
That’s all you are done.
