This is really going to sound stupid but it does work. Where you find evidence of a rodent, sprinkle baking soda in the area, enough so when the mice come back to the same area, they will run through the baking soda.
At some point, the mouse will start cleaning himself by licking the baking soda off his paws and that is how he will "ingest" the "poison".
Since mice cannot pass gas, the baking soda will be trapped in his stomach and he will implode from within resulting in death. One of the best things about using baking soda compared to real poison is that if you have a cat or dog that runs across the mouse, it can't hurt them.
I never knew that mice don't fart. :laughing:
