"Co2 bombs" for slugs.
I have recently found what I believe to be baby slugs in my largest viv (four years old 36x36x18). I have been reading about eradication techniques and it seems that a couple "Co2 bombs" is the most widely accepted method. I am having a hard time finding info on exactly how to do this/where to get Co2. Does anyone have a suggestion for alternate methods or perhaps can anyone provide some guidance on how to properly use this method? Please send help! Thank you much.
