If your husband’s aversion to the glue trap is that they are inhumane and kill the animal- they don’t have to be/do either. Once a mouse or rat gets stuck in the glue, you can take a stick or broom and push the stuck animal and the whole trap into a box or bucket, then take it somewhere far away (hopefully not to someone else’s house to be someone elses problem but maybe a park,etc). gently push the rat and trap out, and just pour plain vegitable oil over the trap’s sticky surface. Doesn’t matter if you get it all over the rat-won’t hurt him a bit. Then stand back! Like magic, the oil somehow completely neutralizes the glue and the rat is free! It’s a neat trick and you don’t have to touch the trap or rat if done as suggested, and the rat will be happy as a …well, rat!
I’m sure lots of people will say its crazy to save a rat and I must admit I probably wouldn’t. But glue traps are one of the most effective ways to catch a rat and it sounded like the cruelty or lethality is why (maybe) your husband doesn’t want to use a glue trap. Anyway, crazy or not just wanted you to know its an option. Good luck!
