You'll have a lot more success using something like snort or tcpdump to 
catch them.  For example, you could easily write a couple of rules that 
would catch any IRC communications, regardless of the port used.

alert tcp $HOME_NET any -> any any (msg:"IRC communications"; content: 
JOIN; sid: 1000000; rev:1;)
alert tcp $HOME_NET any -> any any (msg:"IRC communications"; content: 
PRIVMSG; sid: 1000001; rev:1;)
