Though they may look similar at first glance, rats and mice are actually quite different creatures. And when it comes to your home, you definitely want to know which one you’re dealing with. Here’s a quick breakdown of the main differences between rats and mice so you can be sure to identify which pest is invading your space—and how to get rid of them!
One of the most obvious ways to tell rats and mice apart is by their size. Adult rats typically weigh in at around 500 grams, while adult mice usually don’t exceed 30 grams. This size difference can be helpful in determining which rodent is causing damage to your home, as rats are more likely to gnaw through tougher materials like wood, insulation, and wiring. Mice also have smaller feet, which means their footprints will be correspondingly smaller than those of a rat.
Another way to tell rats and mice apart is by looking at their droppings. Rat droppings are typically much larger—around 18 mm long—whereas mouse droppings max out at around 8 mm. And because mice produce more waste per day than rats do, you’re likely to see larger amounts of mouse droppings near areas where they’re active. Mouse droppings are also more pointed at the ends, while rat droppings are more blunt.
Different Behaviors and Habits
Mice tend to be more active during the daytime hours, whereas rats are most active at night. And while both rodents will nibble on food scraps and other bits of human garbage, rats are much more likely than mice to gulp down their food whole without chewing first. Rats are also better climbers than mice, which means they’re more adept at getting into hard-to-reach places like attics and crawlspaces. Finally, rats tend to be loners, while mice are social creatures that will often live in large colonies.
