Do Cockroaches Poop? How To Identify and Get Rid of It
Yes, cockroaches do poop and their droppings aren’t always easy to spot, especially if there are only one or two in that part of your home. When you finally do find clusters with cockroach droppings all over them – it may be a sign of an infestation!
Cockroach poop is identifiable based on its color, size, and texture. Their droppings will be a dark brown color, waxy in texture, and smear like a thick film. Depending on the species of cockroach, the droppings could be large, like a grain of rice, or smaller in size, like coffee grounds. The droppings could have rounded ends and ridges along the sides.
This type of semi-solid waste material can vary depending upon which species you have, it is important to know which kind and how many so you can apply the best pest control methods.
What Cockroach Droppings Look Like?
Cockroach droppings are small dark brown or black angular-shaped pieces that cockroaches leave anywhere they walk. You can find cockroach droppings on kitchen countertops beside sinks, on the floor underneath appliances, and even inside your cabinets – inside food containers and cereal boxes!
Cockroaches defecate before or just after they eat. Cockroach feces often have a shiny or greasy appearance because cockroaches digest food by liquefying it before they consume it.

What’s Inside Cockroach Droppings?
As cockroaches eat their food, they digest it and excrete any waste products behind them. What is leftover from this process is the cockroach’s feces which will contain undigested pieces of food, pheromones, bacteria, dead cells, and protozoan cysts. Depending on the species these are generally lighter or darker because cockroaches have evolved to match their surroundings.
Since cockroaches can carry a number of pathogens, cockroach feces should be handled carefully. The most hazardous health issues include allergic reactions and internal poisoning from cockroach fecal droppings.
If contaminants are left on surfaces for long periods they may cause adverse health effects on the inhabitants of the infested premises. This is because cockroach poop often contains allergens that can cause various reactions in people who are sensitive to them.
In some cases, cockroach waste has been known to cause severe allergies leading to asthma. In addition, constant exposure to cockroaches can leave a residue that causes gastrointestinal diseases.
How Do You Identify Cockroach Poop?
Cockroach feces are hard or solid, with a waxy texture and a minimal amount of water. Their excrement looks like rat or mouse waste.
Cockroach feces are usually found in cockroach-infested homes. They look like black or dark brown specs that look dusty and a little bigger than a grain of rice.
The cockroach poop is often seen near cockroaches, so they can be identified by the cockroaches themselves. In some instances, cockroaches are seen rubbing their bodies on the cockroach poop, which is how they recognize it.
It’s also important to look for cockroach feces in cockroach-infested areas because an infestation can tell you that your house has cockroaches.
Cockroaches tend to eject feces from their anus, so cockroach poop will vary depending on the cockroach’s age. For example, cockroach nymphs (baby cockroaches) will have very little cockroach feces because they are not old enough to reproduce.
A cockroach that is capable of reproducing will have a darker cockroach poop because it has digested more food before expelling cockroach feces.
Cockroach poop can also vary depending on their diet, so cockroaches that have a higher-carb diet may have darker cockroach poop than cockroaches with a low-carb diet.
What Does Cockroach Poop Smell Like?
Cockroaches love filth and their excrement has a distinct odor that is similar to the meals they consume. They give off an acidic, foul, musty, moldy, or mothball stench.
Where Do Cockroaches Poop?
Cockroach droppings are usually found in dark areas of the home or building where cockroaches hide during the daytime hours. These are typically along, inside, or behind baseboards; underneath the sink; around pipe collars; on ceilings (behind wallpapers or ceiling tiles); and under kitchen appliances like the refrigerator, oven, dishwasher, and garbage disposal. Cockroaches may also nest in sewers and leave droppings on your property.
If the cockroach population is large enough, you’ll start to notice cockroach feces noticeable in areas where cockroaches gather together :
- In the kitchen – behind the stove, underneath the dishwasher & refrigerator, inside cabinets & drawers, around sinks and drain pipes
- In the corner of low-lit rooms – such as attics, storage cupboards, and closets
- In the bathroom – the back of toilets, inside cupboards
- Outdoor hiding places – such as nearby trash cans
- Around cockroach entry points – doors, windows, and cracks in walls
When cockroaches infest a new home, cockroaches typically enter through small cracks by doors or windows. The cockroaches are looking for food and water that is frequently found in kitchens. Cockroach feces will be seen on or around kitchen counters where cockroaches forage food particles left behind by humans. Cockroach feces will also be visible in areas where they frequent most often like under the sink, near drains, etc.
Do Cockroaches Poop on Walls?
It is natural to ask if cockroaches poop on walls since cockroaches crawl along the walls.
When cockroaches walk or fly around, they leave some feces behind which you may see near their nesting areas that are usually hidden in uncertain places where people cannot spot them easily. Sometimes cockroaches poop on floors, tables, or any other surfaces where cockroaches can walk on.
Can There Be Droppings But No Roaches?
It is possible to see cockroach droppings without seeing cockroaches. Even if cockroaches are present, you might not see them at all times. Further, cockroach feces can be located just about anywhere in your home or business that cockroaches frequent.
There might be droppings from roaches that used to live on your property but have died or left (like as a result of past extermination). Unless a roach eats it or you knuckle down and clean it up, the droppings will sit there indefinitely, slowly decaying and sometimes molding for many years.
The best way to find out if you have an infestation is to clean up any cockroach droppings and wait a few days to see if any more appear.

Cockroach Poop Vs Other Pests
Rats, mice, termites, and cockroaches all produce feces that is comparable. There are several types of pests to deal with, but they all need distinct techniques. Examine the waste for these distinctions before taking action.
Difference Between Rat And Large Cockroach Poop
Even if your roaches are huge, rat poop will be significantly bigger. It will be much thicker, whereas large cockroaches will only produce waste the width of a rice grain.
Rat droppings are also pointed at the end, not rounded like cockroach poop.
Difference Between Mouse and Cockroach Poop
Like rat droppings, mouse feces are larger than cockroaches’ poop. They have short hairs in them and pointed ends, which are both not characteristics of roach poop.
Difference Between Termite And Cockroach Poop
Termite droppings also look like cockroach droppings in size and texture. However, they have some unique characteristics to set them aside from cockroach poop – including:
- Termite droppings are multicolored, unlike the brown or black roach poop
- Their poop is pellet-shaped, not rice or coffee-ground-shaped
- The poop is six-sided, unlike a roach’s clean cylinder shape with ridges
- Termite poop is in almost all cases found in or near wood. Roach poop can be found anywhere (although some cockroaches have been found to eat wood when food sources are scarce)
What Do Different Types of Cockroach Poop Look Like?
So, you’ve discovered the poop. You’ve decided it’s cockroaches. You’re aware of the species’ size. It’s now time to narrow down your specific cockroach infestation. You can choose the appropriate extermination approach by knowing the species that are terrorizing your home.
What Does German Cockroach Poop Look Like?
German cockroaches are somewhat smaller in size (about half an inch long). They are one of the most prevalent pests in the United States. The main identifying feature of the cockroach is their reddish-brown hue, as the cockroach’s feces are a similar color. German cockroach droppings can be found near bathrooms, kitchens, laundry rooms, and other humid locations.
Before you ever see them, you’ll notice their feces. They’re nocturnal and like to run about when people are asleep. Their small stature makes them virtually silent, allowing humans and even dogs to miss them.
When the roach’s nest is overcrowded or disturbed, only then will German roaches appear. Their droppings are black or brown in color, small, round like ground coffee or pepper. They can usually be seen as dark spots in the corners of rooms.
What Does American Cockroach Poop Look Like?
The American cockroach is considerably larger than the German cockroach. It has a size of between 1 and 2 inches. It’s usually reddish brown in color. The thorax will have a light yellow border.
Cockroaches are often encountered in bathrooms, kitchens, and storage areas. The adult American cockroaches leave long, dark brown to black cylindrical droppings with ridges and furrows on them.
What Does Oriental Cockroach Poop Look Like?
The Oriental roach is black and an inch long. It’s smaller than the American roach but far bigger than the German roach. Its robust build and ridged back distinguish it from other cockroaches.
This species thrives in locations that are far wetter than its relatives. While Oriental roaches can live for a month without food, two weeks without water is harmful. You will find them in bathrooms, cellars, and sewers. Oriental cockroach droppings are dark, thick, and coarse approximately ½ inch long with pointed tips.
What Is The Difference Between Cockroach Poop and Eggs?
Cockroach eggs are small, brown, or white in color, about 1/8 of an inch long. They harden and darken to a red-brown color as they mature.
Unless you take a closer look, this may resemble cockroach poop.

Cockroach eggs are often laid in a mass, which is glued together by cockroach saliva. One female cockroach can produce about one egg sac per week.
If you notice cockroach eggs in your home, this means that you have a very large cockroach infestation on your hands and should immediately take action to get rid of the cock
Cockroach droppings are so tiny that they can be difficult to spot even when the eggs are small. It’s likely an egg rather than a drop if you see something brown that’s less than ¼ inch distant.
Are Cockroach Droppings Dangerous?
Cockroaches feed on filth and keep many disease-causing germs, viruses, or other organisms in their feces. If you consume their feces (incorrectly in your food), you risk contracting a slew of illnesses including diarrhea, dysentery, E. coli infections, typhoid fever, abdominal discomfort, leprosy, and even polio.
Why Should You Find Cockroach Poop?
Firstly, the droppings can act as an attraction for other roaches. Cockroach droppings are an indication that other roaches have arrived. Roaches have a powerful sense of smell. They can detect the presence of other roaches and will flock toward them. This indicates a flourishing nest if there is an abundance of feces. That’s great news for new cockroaches looking for a place to live.
Even if you remove the present roaches, more will return if the mess isn’t cleaned up. Pest control experts frequently take advantage of this fact. They’ll put traps around the droppings to capture and remove any roaches that escaped during the first cleanse.
Secondly, The Asthma and Allergy Foundation of America clearly states that cockroach waste causes allergic reactions; their waste can also trigger asthma symptoms and can lead to asthma attacks.
The roach poop can also contaminate your food. This can lead to gastroenteritis, diarrhea, and dysentery.
The cockroach infestation will only grow if the droppings are not removed or exterminated.
Can Cockroach Droppings Make You Sick?
Yep, cockroaches absolutely poop, and cockroach droppings can make you sick! Cockroach feces contain allergens that can cause allergic reactions such as sneezing, watery eyes, and asthma. It is important to get rid of cockroach feces quickly and safely.
Is Cockroach Poop Poisonous?
It is generally agreed cockroach droppings are not poisonous. They do, however, release a strong pheromone that stimulates cockroaches to feed. This makes cockroach feces quite dangerous because cockroaches can spread disease-causing bacteria and viruses from contaminated food, surfaces, and even other cockroaches, which is why it’s important to eradicate cockroaches quickly and efficiently. According to a study published in the Journal of Medical Entomology, bacteria in cockroach droppings can cause food poisoning or other stomach disorders.
What Happens if You Eat Cockroach Droppings?
You would probably be sick. Eating cockroach feces can cause dysentery, diarrhea, E Coli infections, typhoid fever, leprosy, and polio.
You may not notice any symptoms for a few hours after eating cockroach feces. The immune system of your body builds defenses and combats the infections that have entered your body during this time.
Can Cockroach Poop Kill You?
Cockroach feces have a detrimental impact on one’s health, and some unaddressed symptoms might lead to serious illnesses. Individuals with weakened immune systems are at a greater danger of developing allergic responses if they are exposed to these allergenic compounds. Children, elders, and individuals who have had their immunity weakened by illness can also die from severe cockroach infections.
How Do You Get Rid of Cockroach Poop?
Once you are sure that it’s cockroach droppings that you have found, you need to do the following three things:
- Clean away the cockroach droppings
- Get rid of the roaches
- Prevent a new roach infestation
As a result of the steps described below, you’ll be able to eliminate their danger for months if not years. You shouldn’t miss any of them; otherwise, you’ll be vulnerable for a long time.
Clean Away Cockroach Droppings
When cockroach waste is swept away without caution, it may transmit dangerous pathogens. Because roach waste is contaminated with a variety of pollutants, you must clean up safely.
Step 1 – Protect Yourself
When cockroach droppings come into direct contact with the skin or are breathed in, they become dangerous. If you touch the droppings with your bare hands, or if they brush against you, this is extremely hazardous. The pollutants have now entered your body and may come into contact with food, your mouth, or other items.
Before you go to work, put on your coat. Old clothing will do fine, and use gloves if necessary. To reduce exposure to possible airborne allergens, purchase a respirator or a face mask that protects the mucous membranes of the eyes and nose.
Keep children and asthma sufferers away from the area whilst you clean.
Step 2 – Vacuum
When you find roach feces, your cleaning approach will vary depending on the location. Vacuuming is usually the best way to remove hard droppings from carpets, cupboards, furniture, and clothing. Vacuum cleaners with HEPA filters are available and make it much easier for people who have allergies, as they’ll be breathing in cleaner air around them while vacuuming! If you don’t have one though then just remember to protect your eyes and nose with a mask or respirator.
Step 3 – Wipe Down Surfaces
Once you’ve vacuumed, wipe down surfaces that cockroach droppings might have touched. A disinfectant spray like Lysol is good for this, but any non-ammonia cleaner will do. Don’t forget to wipe down the floor too; cockroach droppings can be even more dangerous in high humidity areas, like kitchens and bathrooms.
Step 4 – Throw Away Droppings Safely
To prevent the germs from spreading, seal the trash bags you have used to dispose of the droppings. It’s not a good idea to leave this in your home for any longer. Rather, get it to your waste collection center as soon as possible.
You’ll want to dispose of any vacuum bags that have been used to clean cockroach droppings as well.
Get Rid of The Roaches
The following cockroach extermination methods will not only ultimately eliminate cockroaches, but also teach you how to take action safely and responsibly:
- Chemicals – The most common way to kill cockroaches is with the use of household bug spray. After spraying around the home area, be sure to cover all food supplies not in packaging or storage containers (Boric acid is also great for both killing cockroaches and preventing any new infestations). While they can be an effective tool in eliminating cockroaches, chemicals should be used with caution.
- Baits – Bait stations are an excellent way of getting rid of cockroach activity because they simulate a delicious meal for the roaches which then eat the poison that has been placed inside (most cockroaches eat sweet things). The cockroach eats the poison and then gets back to his cockroach buddies which will get eaten up too!
- Traps – Cockroach traps are a great way of monitoring cockroaches. Traps work by luring the cockroach in with attractive food, before trapping it inside. A glue board can be used to trap cockroaches, cockroach control glue boards are also an option.
Prevent a New Roach Infestation
Once cockroaches have been removed from your home, they will return unless you take steps to stop them. This is not easy because cockroaches are known for their resilience.
Step 1 – Find the Source
In order to prevent cockroaches from coming back, you need to find where they are entering your home. Cockroaches can squeeze through holes as small as a pencil width so it’s important to look for any cracks or openings around pipes and windowsills. Use steel wool to seal these areas off, making sure that cockroaches have no way to enter your home.
Step 2 – Fix Leaks
Roaches are attracted to water so you need to fix any leaks in your home, especially around sinks and washing machines. Any cockroach feces found near a leaky pipe should be considered an emergency situation so deal with it as soon as possible.
Step 3 – Fight Organic Matter
Cockroach feces are commonly found in areas with high organic matter like mulch or dirt. You can discourage cockroaches from entering your home by making these areas less attractive to them. Cover the ground around your home with gravel, stones, or something similarly coarse. In particular, cockroaches have a strong affinity for moist soil so don’t plant anything in it or near your home that will increase the humidity.
Step 4 – Get Rid of Cockroach Food Sources
As cockroaches are omnivores, they’ll eat almost anything in small quantities. Don’t leave crumbs on counters or food in the sink. Wash plates and utensils as soon as you’re done eating. If cockroaches are eating your pet’s food, make sure to clean up after them.
Step 5 – Take Out the Trash
This one’s a given! Keep trash bags tightly sealed and use them for no longer than two days to discourage cockroaches from using it for warmth.
Step 6 – Seal Your Home
Sealing cockroach entry points in your home is a very effective way to prevent cockroaches from coming back. Once the cockroaches have been removed, repair any cracks or holes you find around windows and doors.
