Rat droppings: identification and what they tell you
Droppings are often the first proof of rodents. Size, shape and where they sit tell you whether you are looking at rats or mice, and whether the activity is current.
What they look like
Brown rat droppings are typically 12–18 mm, spindle or capsule shaped with blunt ends. Mouse droppings are much smaller, like grains of rice, and often scattered.
Fresh versus old
Fresh droppings are dark and slightly soft. Older ones dry, fade and crumble. A mixed pile can mean ongoing use of the same run.
Where they collect
Rats leave groups along walls, in lofts, under decking and near food stores. Finding them in a kitchen and a garden shed on the same site often means a travel route between the two.
Hygiene
Do not sweep dry droppings without damping them first. Wear gloves and wash surfaces with detergent. If you are unsure, leave the evidence in place for the survey.
