Bad bots may be from google bot or any other bad bots. To reduce the same first you need to find which bot is affecting the bandwidth and memory. 

Find the log from below command: 
sudo grep "05/Nov/2015:0[1-2]" /usr/local/apache/domlogs/ulifeqxj/ulifephoto.com | grep -i "googlebot" | wc -l
sudo grep "05/Nov/2015:0[1-2]" /usr/local/apache/domlogs/ulifeqxj/ulifephoto.com | grep -i "bot" | wc -l

Once you found which bot is causing the issue, you can block it by adding rule in .htaccess.
