how to kill & preserve large crickets

[francisento]

my question is, how can I instruct an unexperienced collector on how to kill and preserve large, fat crickets?
killing: -is it best to place the specimen in a freezer?
-or throw it in boiling water?
(Ethyl Acetate = complicated for instructing)
preserving: when it's dead, how shall it be preserved to obtain the
colours and for oversea shipping?

Thanks in advance for any advice!

How come? Just put some nail polish remover on a piece of cotton, it will work similarly.
Sorry, can't give you specific instructions for large crickets since I've never collected them. When I collected medium size grasshoppers I just killed them with Ethyl acetate and dried.

There's already similar topic in Mantodea and Phasmida. All Orthoptera can be killed and preserved the same way. Freezer is the best way to kill them.
