What do Cockroach Droppings Look Like?

Have you recently found innocent-looking brown spots scattered across your kitchen floor? I know that when I saw them, they made my heart jump out.

Being unaware of the markings left by cockroaches can cause a small infestation to grow out of control. These stubborn creatures are great survivors so it’s always easier to fight them off at the beginning.

One of the telltale signs that you have a big colony of roaches hiding somewhere in your home is finding cockroach poop in corners and on the floor.

How Roach Poop Looks Like?

It’s sometimes difficult to tell that you have a roach infestation around the house. Roaches are nocturnal creatures so they’re likely to hide all day until you’re asleep and the house is quiet. They also hide in corners and crevices that you can’t easily see.

However, one of the signs that helped me know that I needed to act promptly to get rid of these filthy creatures was finding roach poop. Finding droppings of any creature in the house is usually sad and depressing. Nevertheless, you should be able to identify what this is so you can act accordingly. So what does roach poop look like?

Regardless of their species, all roaches will have the same color of roach droppings. All roach feces are deep brown but the size differs according to the type and size of the roach.

Here is how they usually look like.

Smaller roaches like the German cockroach leave small markings that look like ground coffee or pepper. Some feces will look like stains. The babies of these roaches are very small and their droppings are usually very difficult to see. It’s quite easy to confuse them with something else.

Bigger species like the American cockroach or palmetto bug will leave bigger droppings. The palmetto bug poop is solid and looks like brown crystals. Droppings could be the size of a grain of rice and will have round ends.

It’s easy to spot the difference between the droppings of roaches and mice or rats if you look at roach poop pictures. Mice droppings have pointed ends, unlike roach poop that has rounded ends. Moreover, the sides on roach shit have some ridges that can’t be found on mouse droppings.

I understand that it can be quite difficult to identify these differences at home, so in case of suspicion, you might want to pick your protective gloves and a magnifying glass to make sure of what you’re dealing with. It’s always better to act based on real information.


What Harm Cockroach Poop Cause?

Unfortunately, there are more issues associated with cockroach feces than how disgusting they look like. Roach droppings can cause serious health issues that can affect you, your pets or anyone in the family.

  • Roach droppings contain special proteins or allergens that can trigger an allergic reaction. Touching them accidentally is utterly disgusting but it can also cause a skin allergy.
  • The allergens found in their fecal matter can trigger asthma.
  • Cockroaches don’t produce any poison, but they’re hosts to pathogens like salmonella. If these pathogens get in touch with your food or drinks, they will cause severe contamination that leads to serious illness.

Here are a few things that you should do if you find roach droppings in your house.

  • Make sure that you’re wearing protective gloves and a mask before you come close to the feces.
  • Don’t attempt to touch them with your hands.
  • Hold the droppings, if possible, and examine them to make sure that they’re roach poop and nothing else.
  • Get rid of them and disinfect the area as promptly as possible because roaches can eat their feces if no food is to be found.

  • If possible, put the mattress outside to dry in the sun. The sun will kill any bacteria or germs to guarantee the cleanliness of your mattress before it’s ready for use.

Closets and Clothing

Roaches prefer the dark undisturbed spots so they will love to roam around your closet. Check the corners and the floors of your closet for any roach droppings. They’ll probably be in the part where you’re keeping clothes for the next season and not the ones you use every day.

If there are cockroach droppings inside the closet, then there might be some of them on your clothes too. Putting on these clothes can cause severe allergic reactions. They will probably smell bad, too.

  • Try to scrape off any stains or droppings.
  • If the stains are too stubborn to remove, soak your clothes in an enzyme product. This is the only solution that can break the proteins to help you get rid of the feces.

  • Vacuum your rug to get rid of all the droppings, especially the big ones.
  • Use carpet shampoo to remove all the stains. Most of the shampoos contain enzymes that break proteins. Use a rough brush or sponge to scrub the carpet.
