Written by

Today, almost every house suffers from a pest infestation. Unfortunately, some pests, like roaches, pose some dangers to home occupants. Cockroaches are not only a health hazard to people with asthma but also carry disease-causing germs.

When these pesky insects come to your home, they leave behind some evidence. One of the most common signs of a full-blown infestation is the presence of roach poop in your home.

Apart from invading your home, roaches will also make it their toilet. However, while cockroach poop in your home can make you disgusted and angry, it can help you determine where these insects are hiding. You can then use this knowledge to take the necessary measures and get rid of them.

Continue reading this guide to help you identify cockroach poop and how to differentiate it from termite poop, mouse droppings, and rat poop.

What’s Inside Cockroach Excrement?

All kinds of things that the insects have eaten is inside cockroach excrement. These can be cardboard boxes, garbage, rotting meat, dead insect, or food.

In addition, these insect pests do not urinate. Instead, they secrete both solid and semi-solid waste—all of which vary depending on size, appearance, roach species, and the age of the cockroach.

Identifying Cockroach Droppings

Cockroach droppings can help you tell the size and type of roach you are dealing with. Additionally, by examining the poop, you can rule out the presence of other pests in your home and improve your mitigation strategies.

Roach poop has various characteristics. For instance:

Shape and Size

The size and shape of the poop you see can help you know the size of cockroaches you have in your home. Needless to say, small roaches excrete small droppings, and large roaches produce bigger droppings.

Small Cockroach Poop

Small roach species like the German cockroaches and brown-banded roaches have small poop. The roach droppings are like tiny black crumbs sprinkled across the area. At a distance, these droppings might appear like ground pepper or coffee grounds spilled on the floor.

However, after inspecting it closely, you will notice that the cockroach droppings are rounder in shape.

Large Cockroach Poop

Oriental, American, and smoky brown cockroaches are all large species of cockroaches. They usually are one inch long and produce solid, cylindrical droppings resembling rice grains.

Since this cockroach poop can be confused with mice or rat droppings, you must do a close inspection.  Otherwise, you will end up chasing after imaginary rats leaving behind a roach infestation to grow.

Color

All cockroach feces have a definite dark brown color which might sometimes look more black, depending on what the roach ate, its age, and any adjacent contaminant.

While you can determine the species and size of the roach by analyzing its poop size, you cannot do the same with the color.

The poop color is the same in all cockroach types. Thus, color does not help you tell whether you have German, Asian, or American cockroaches in your home.

Texture

Roaches do not urinate; instead, they excrete semi-solid or solid droppings. So, if the poop is not whole, look for stains or smears.

Additionally, the feces are semi-solid and will not soak onto other surfaces. Instead, they will leave behind raised marks.

That said, you must carefully examine the cockroach poop by:

  1. Wearing latex gloves
  2. Lightly smearing the cockroach droppings
  3. If it is cockroach poop, it will not be evenly smooth and will smear in a waxy texture. Conversely, mice or rat poop will smear in a greasy or wet manner.

You might be confused if you have recently seen other pests in your house. For instance, you are wondering whether the roach droppings belong to a rat you saw last week or a roach you came across in the kitchen at night.

Cockroach Poop vs. Termite Poop

Termite droppings are somewhat similar to roach dropping in terms of texture and size. However, you can tell them apart because:

  • Termite poop has different colors, while roach poop is either brown or black, depending on its age, what it ate, or any surrounding contaminants.
  • Termite droppings are mostly found near lumber, but you can find roach poop anywhere else in your home.
  • Termite droppings have six sides, while a roach’s poop has a cylindrical shape with edges.
  • Their droppings look more like pellets, not cylindrical, or like black pepper, coffee, or rice grains.

Remember that the color of termite droppings will depend on the wood they eat.

Large Cockroach Poop vs. Rat Droppings

While cockroach poop might resemble rat poop, various characteristics can help you tell the difference. For instance:

  • Rat poop has a pointed edge, while cockroach poop is rounded
  • Rat poop is thicker than cockroach poop, no matter how big the roach is.
  • Rat feces are wider, while cockroach poop will be the size of coffee ground, black pepper, or rice grain.
  • It is almost the same length as mice’s dropping but much longer than cockroach poop.

Mouse Droppings vs. Cockroach Poop

There is a big difference between a cockroach’s size and a mouse’s. Thus, roaches can squeeze their bodies into smaller spaces compared to mice.

That said, if you find poop in a place where a mouse cannot fit, chances are that it belongs to a roach. On the other hand, mouse droppings look more like mammal poop, while roaches’ poop is more regular and uniform, like rice grains.

Places in Your Home You Can Find Cockroach Poop

Cockroaches don’t have a designated bathroom in your home and will defecate anywhere. In addition, they tend to poop where they spend most of their time. This can be near their nesting area or water and food sources, which can play a significant role in getting rid of them.

Knowing where the roaches eat or drink water will allow you to cut off the supply and leave them starving. Besides, you can follow that with a homemade roach control remedy to get rid of them.

In addition, knowing where roaches are nesting in your home will allow you to target a larger roach population and have a successful roach eradication process.

So, if you have spotted signs of cockroach infestation like shed exoskeleton, you can start tracking them down using their droppings.

The following are common places in your home to find cockroach droppings:
