My BF had a mouse in his apartment. He put down sticky traps. Then, of course, he gets called to Manitoba for work for three weeks. Naturally, I'm the one who is assigned the duty of watering all his plants.
First time I go for my plant watering, I notice the whole place smells like poo. As I'm doing my rounds of the plants, I almost step in a sticky trap with a dead mouse that I didn't realize he had placed by the plants. Naturally, I freaked out but managed to get the mouse and the trap into a garbage bag, then downstairs into the garbage disposal bin. Yuk!!!
I went back today to do the plant watering duty, and the place smelled normal again.
Lesson here: dead things stink and are gross.
One time, Fred caught a mouse that disapeared. Less than a week later, my whole house started smelling of baby poo. yuk. I found a rotting mouse under some furniture that cats couldn't access. After I disposed of it the place smelled okay again. Yuk, Yuk.
