I have so many baby mice its not even funny, and I am going to switch over to frozen thawed and am looking for an ethical and easy way to kill my mice that is not cruel in any way. So i can vacuum seal them and freeze them. Any ideas on how to do this>? Someone told me to soak a sponge in ether starter fluid and stick it in a box with the mice and they will die instantly, but will this harm my snake when she consumes them? any ideas will be helpful. And no, I am not slapping 38 mice on my counter top.
