twitterdrip on "How to stop httrack and more"

Hello i was wondering how would i include this code

RewriteEngine on
RewriteBase /
RewriteCond %{HTTP_USER_AGENT} almaden RewriteRule ^.* - [F,L]

in wordpress htacess file that contains

# BEGIN WordPress

# END WordPress

# BEGIN wtwp_cache
# END wtwp_cache

# BEGIN wtwp_security
# END wtwp_security

so i can prevent people from scraping me
