What Do Cockroach Droppings Look Like – How to Identify Cockroach Droppings

Roach infestations in homes are very common. Even if you think you have a clean house, there are many cockroaches. If you are a homeowner, you may not know what to do about this problem.

You can ask a pest control company to come and inspect your home for cockroaches. But this is a very expensive solution. You can also use a roach trap to catch the pests. There are many types of roach traps. A very effective way of catching cockroaches is to use cockroach bait.

This method is very effective. But there is a problem with this method. When the bait is placed in a home, you will attract a lot of cockroaches to the bait.

 The first way to identify cockroach poop is to know that all roach droppings have the same color. However, they come in different sizes, depending on their sizes and types. When identifying cockroach poop, look for 3 main characteristics:


A cockroach’s droppings vary in color from light brown to dark brown, according to its diet. Droppings are usually light brown because the roach’s diet includes vegetable matter. When a roach eats meat, the droppings tend to be darker. The color of a cockroach’s droppings can be used to distinguish the species from other species.

The color of the droppings is often the first clue you will notice about a cockroach infestation. But, like many other insects, cockroaches shed their skin and molt throughout the year. This means the color of the droppings will change over time.

Size And Shape

As you may have already guessed, cockroaches tend to be small in size. Their droppings are usually no more than a few millimeters in diameter. Cockroaches will leave their droppings in dark places.

The places where they are most likely to drop their excrement are behind your refrigerator and under the sink. To prevent roaches from coming into your house, place traps in these areas. You should clean out these traps after a few days. You can also spray cockroach poison throughout your home.

Small Cockroaches

There are many types of animals that poop. Some animals poop when they are eating or drinking. Others have different ways of pooping. Sometimes, they make a small pile of droppings. On the other hand, there are animals that have big piles of droppings. The type of poop they produce can differ too.

Some animals will produce soft feces. Other animals will poop hard. We have mentioned two types of droppings: black and brown. There is another type of poop called mouse feces. It has the appearance of a tiny, white, grainy substance. It can be found on the ground near rodent holes or in the nesting areas of rats and mice.

Large Cockroaches

For large species, such as the American or Oriental roach, their waste will be like rice grains. They’re shaped like solid crystals or cylinders. The ends will be rounded, with ridges along the sides.

These droppings are often confused with rat or mouse droppings. You may require a magnifying glass to notice the differences. While that sounds excessive, putting out mouse traps by mistake will only let your cockroach infestation grow uncontested.


If the droppings are not whole, they may look like smears or stains. Cockroach feces have little water content, so they will not soak into fabric or other surfaces. Instead, the mark will be raised. You may need to inspect them more closely, as small droppings will seem like ink stains. Here’s what to do:

  • Put on a rubber or latex glove for hygiene purposes.
  • Gently smear the dropping. It will wash out of fabric, so don’t worry about damaging your clothes or towels.
  • Upon doing so, you’ll find it’s not entirely smooth, like ink. The poop will smear unevenly with a waxy texture. In contrast, rat or mouse droppings will smear but in a greasy, wet fashion.

Where To Look for Cockroach Droppings

When you are in your home, you may notice that cockroaches sometimes defecate in your home. You will often notice this when you see them near your kitchen counter. Cockroaches are attracted to food and will usually eat or drink anything. The droppings they produce are generally dark brown in color.

This means that they may be using your kitchen sink as a personal toilet. This is why it is important to clean your kitchen sink thoroughly after every meal. The same applies to your refrigerator and garbage disposal. If you don’t clean them regularly, you will end up with a lot of bacteria that can make you sick. Cockroaches are pests and can also carry diseases like typhoid and typhus.

  •  Locating the nest will help you eradicate the infestation.

If it’s one or two cockroaches, knowing their feeding area can help you cut off this food supply. The cockroaches will then leave or starve.

The Oriental cockroach has dark-colored stripes on its back and on top of its head. It also has large legs and antennas. Its back is flat and it has a short snout. The Oriental cockroach is mostly found in warm places. It can be found in both urban and rural areas. It’s also found on the west side of the United States. It prefers moist environments, especially damp environments.

  • Basements, especially if it’s recently flooded or leaked. Even those that experience a lot of condensation build-up will be prime targets.
  • Bathrooms, especially in the nooks and crannies around a shower or bathtub.

Kitchens, especially around the sinks.

While the areas described above may be ideal, cockroaches will still leave these spots to seek food.
