Hello Rusty!
   The best cricket removal tool of course is someone, who captures or kills 
it.
   The next best thing could be playing with phase inverted signals. If you 
have two microphones, you could connect them both, use one for your recording 
and direct another away from your own noise production. If possible as 
striahgt as you can towards the offender. I'm not absolutely sure about all 
the mechanics of such a process, but it shold work, if the signals are 
synchronous. Others might have to say more about that.
   the other option is filtering and EQ'ing. If th cricket doesn't cover too 
much sonic space or doesn't interfere too much with your intended frequencies, 
you could try an equaliser. You can sweep the bands and find the sweet spots 
for the cricket and lower them as much as possible. If the cricket offers a 
lot of high frequencies you could probably even work with some more drastic 
lowpass fitlering. that doesn't work for every instrument.
   The third - and from a technical point easiest - method would be to compose 
a lullaby or other nature-friendly music and claim, that the cricket is 
intentional and from your personal sound library. :-)
   Chirping regards
