The top trap in the picture is a rat trap and the one on the bottom is a mouse trap. There is no change in how the traps work, but mice are much smaller than rats, so a mouse could be light enough to steal the cheese, and not set off the the rat trap. Rats are bigger and hardier, so even though it sets off the mouse trap, it doesn’t die. Therefore, you have to get a rattrap if you have rats, and a mousetrap if you have mice. You want to use a mousetrap or rattrap because mice and rats can get to the foundations of your house and will eat and chew the foundations into oblivion, which will make your house come crumbling down, which is not good. They can also carry disease, both directly and indirectly. They can spread disease directly by biting you, which will cut open a hole in your flesh, then their saliva will get in your cut and then you get sick. Another direct method is their urine. Their urine can evaporate and become a cloud of disease. An indirect method mice/rats use is their fleas. Their fleas live in their back fur and will hop off of them, jump onto you, bite you, and infect you with whatever disease they have. There have been thousands of mousetraps before the modern trap became commercially successful. Some of them did not kill the mice/rats but this is bad because it could scare the mouse into peeing which will cause disease and if you let the mouse/rat go, it will just get back in you house.
