According to Section 116125 of the California Health & Safety code, California citizens aren’t just allowed to trap rats and mice, they are encouraged to for health and safety concerns: “Every person possessing a place that is infested with rodents, as soon as their presence comes to his or her knowledge, shall at once proceed and continue in good faith to endeavor to exterminate and destroy the rodents, by poisoning, trapping, and other appropriate means, and to abate the conditions listed in Section 17920.3 that are causing the infestation.”

Calm down, now you know and hey I respect it if you don’t want to kill them and hope you alleviate your problem same as the rest of us that came here. Please just bear in mind that your ethics aren’t the same as mine just like mine differs from the other 2 posters and just because you said ‘inhumane’ doesn’t inherently make your stance the moral high ground and serve as justification to tell others they are wrong.
