Add to .htaccess file:

SetEnvIfNoCase User-Agent "^Yahoo" search_bot
SetEnvIfNoCase User-Agent "^Googlebot" search_bot
SetEnvIfNoCase User-Agent "^Aport" search_bot
SetEnvIfNoCase User-Agent "^msnbot" search_bot
SetEnvIfNoCase User-Agent "^spider" search_bot
SetEnvIfNoCase User-Agent "^Robot" search_bot
SetEnvIfNoCase User-Agent "^php" search_bot
SetEnvIfNoCase User-Agent "^Mail" search_bot
SetEnvIfNoCase User-Agent "^bot" search_bot 
SetEnvIfNoCase User-Agent "bot" search_bot 
SetEnvIfNoCase User-Agent "^igdeSpyder" search_bot
SetEnvIfNoCase User-Agent "^Snapbot" search_bot
SetEnvIfNoCase User-Agent "^WordPress" search_bot
SetEnvIfNoCase User-Agent "^BlogPulseLive" search_bot
SetEnvIfNoCase User-Agent "^Parser" search_bot
SetEnvIfNoCase User-Agent "^Googlebot-Image" search_bot
SetEnvIfNoCase User-Agent "^StackRambler" search_bot
SetEnvIfNoCase User-Agent "^Adsbot-Google" search_bot
SetEnvIfNoCase User-Agent "^WebAlta" search_bot
SetEnvIfNoCase User-Agent "^Googlebot-Mobile" search_bot
SetEnvIfNoCase User-Agent "^YandexImages" search_bot
SetEnvIfNoCase User-Agent "http://www.google.com/bot.html" search_bot
 
<FilesMatch "^.*$">
Order Allow,Deny
Allow from all
Deny from env=search_bot
</FilesMatch>

And the .htaccess file with this code can be placed in any folder on the server that you want to prevent from indexing.
