Identify a Pest By Its Droppings

Sometimes we don’t know we have pests until we find their droppings inside our homes and not only can this be gross to find but also concerning, especially when you’re unsure what it is you’re dealing with. Cut the curiosity and identify the pest in your home by their poop with our handy infographic. And see below for more details on determining the type of pest in your home.

Identifying pests by their droppings infographic


Rats excrete much more than any other pest, as much as 25000 pellets in one year. Should you have rats, you will notice these droppings all over as they go to the toilet as they scurry around, so it’s unusual to see a mass of excrement in one place.  

Rat poop is dark and soft when newly deposited but after a couple of days, the stool hardens and becomes lighter in colour. The droppings of a rat can be as big as ¾ of an inch long and ¼ inch thick. This being said, rat poop does vary depending on the species but it is predominantly the same long, spindle-shape.

Norway Rat

  • Size: ¾ inches long
  • Shape: rectangular and blunt at the ends
  • Found in small scattered clusters  

Roof Rat

  • Size: ½ inch long
  • Shape: curved pellets
  • Found scattered around in lots of locations



Mice are also frequent toileters and deposit lots faecal matter, as much as 27,000 pellets a year! If you have found mice poop, you will see small seed-like droppings that range between ⅛ and ¼ of an inch. Mouse excrement is always found near where they like to adventure, usually where food is, so your kitchen is a likely place to find mouse poop.

House Mice

  • Size: between  and ¼ inches long
  • Shape: small and pointed
  • Brown/black in colour



When identifying cockroach poop, you will find matter that looks like coarsely ground pepper and not only will you find it sprinkled across the floor but on your walls too. Unfortunately, cockroach excrement is sticky and will stay wherever they deposit it. Cockroach dropping are highly toxic and can cause a number of illnesses to humans including salmonella, asthma and many other serious problems.  


Bed bugs

Similar to cockroach excrement, bed bug deposits tiny specks – like the size of a pinhead. Their poop can be found in all soft furnishings in the home but the first place to recognise these are of course, in your bed. Their droppings are usually rust coloured and you will notice small flecks covering your mattress. 



Squirrel poop is oblong and thick, it looks quite a lot like rat excrement but slightly bigger. Their deposits are rounded at the ends and their stool turns white over time. If you have squirrels, you’re likely to find it high up in your attic and scattered around because they can poop on the move.



Like cockroaches, bat excrement is also toxic and can carry disease. Bat excrement is also pellet-like but much rougher in appearance because of their diet that consists of bugs and undigested exoskeletons. Bat poop is found in clusters underneath where they reside, so look up and see if you have this pest.  



Bees release tiny deposits that contain both their wee and their poop combined. Their excrement is dark yellow in colour, which is generally deposited on flowers. However, if you see this in and around a beehive, don’t mistake it for honey.
