I can't think of any critter that will only kill HH'ers you don't
want. Anything that will kill and eat a mantis shrimp will likely eat
damn near anything. There are precious few things that commonly show
up in good quality LR that could be called undesireable, and a slew
of good ones. Myself, I just take the chance, and trap the occasional
mantis or crab.
