“If it’s rice, it’s mice.”
Remember this rhyme and you’ll always be able to tell the difference between mice and rat droppings. As you might guess, mice droppings are roughly the size and shape of a grain of rice, with a dark brown/black colour.
Rat droppings have more of a sausage shape and are much larger, between ¼ and ½ an inch. Rats also defecate in smaller quantities, around 40 times a day, while mice leave behind 50-80.
If you’re unsure whether you have found droppings or something else, you can gather them with a wet paper towel. If they leave a brown stain, they’re droppings.
Both rats and mice urinate and defecate almost constantly as they explore, and even more so when they’re feeding or marking their territory.
This means that if rats or mice have been in your home or business, they’ll almost always leave behind evidence. The more droppings you find, the more rodents are about, or the longer they’ve been there.
To find droppings, you should check along the routes which rats and mice prefer to take through a building, such as along the edges of walls and skirting boards or behind/beneath kitchen units and furniture.
Mice leave their droppings in lines behind them as they move, while rats are more likely to cluster theirs together.
