If you want to disable wget to download your site pages you need to declare wget as bad_bot. For that you need to add the following code in the .htaccess file located under website’s public_html directory.
after you inserted this code, if anybody tries to download your site pages using wget will receive a 403 error.
#Declare Wget a bad_bot
SetEnvIfNoCase User-Agent "^Wget" bad_bot
Allow from all
Deny from env=bad_bot
