Scratchings in the middle of the night, chewed wires and unexplained droppings are all signs that you have a rodent problem. But how do you know for sure and how can you tell, in the first instance, what type of rodent it is? We take a look at how to tell if you have rats or mice.
Noises in the Night
If you hear unexplained noises in the night, the chances are it is a rodent. They are mostly nocturnal which is why you will hear them when you are trying to sleep. Rats are larger and may make more noise than mice however, in the dead of night, any noise can sound loud. Noise alone will not tell you what kind of rodent you have living in your house, only that you need to carry out further investigation.
Physical Appearance – Rats or Mice?
If you have seen a rodent but aren’t sure what it is, a quick Google search may help you to determine whether it is a rat or mouse. However, there are a few key differences between the two:
- Rats are usually larger and a bit more serious looking than mice
- Mouse tails tend to be pink and skinny – rats have darker, fatter tails
- Rats are often darker in colour than mice – mice tend to be brown in colour
- Mice ears are large and round – the size of their ears is big in comparison to their heads. While rats have large ears, proportionately they are small in relation to their head
- The eyes – rats eyes are narrower than the wider eyes of a mouse
- Mice smell musky – you will usually smell something before you see it
The exception can be when an adult mouse is compared with a young rat. The mouse will have larger ears and a longer tail compared to its body length than the rat.
Their Droppings
Examining rodent droppings may not be something that you want to consider but it will help you to identify the source of your rodent issue and whether it’s rats or mice.
Rat Droppings
Measuring between 1/2 and 3/4 inch long, rat droppings are shiny black. This is fresh poop – older poop will be grey and dry
Rat and squirrel droppings are the same size however which is worth considering. The difference between rats and squirrels is that rats will spread out their droppings and squirrels will go in the same spot.
Mice Droppings
These are small and smooth, measuring around a 1/4 of an inch and they have pointed ends. Like rat droppings, new mouse droppings will be shiny, older droppings will be chalky and grey. Similar to grains of rice and you will see more droppings – 40-100 throughout the day in comparison to 20-50 from a rat.

Even if you don’t have a rodent problem, we can put your mind at rest, just like we did for Brenda:
“Matthew came out this morning as we had spotted a mouse – he checked the property and quickly assured us we do not have a problem and it was probably a one-off, very honest as he could have said anything!! He also took time to advise us on how to prevent any further visitors! Also Kerry on the phone was really lovely. Excellent customer service all round which can be rare to find these days. Thank you both.”
