@Frillylily, the slugs die and do not come back. Many little creatures don't have sensory feelings but all little creatures and big creatures do not want to die and they will use what ever measures they have available to live. Being smashed is to physically damage them, being wrapped carefully in a napkin or tissue is not to physically harm them and the freezer would first put them in a sort of hibernation and then they would die in their sleep so to speak. That's is just the way i feel best about things, but drowning in beer doesn't sound so bad either. Honestly, beer has never worked for me to keep the slug population down. The beer always disappears and so do the slugs. I must have been doing something wrong. Then i learned about copper and i haven't had slug problems since.
