What Does Cockroach Poop Look Like?

Small cockroaches’ droppings look like small brown or black specs, appearing similar to ground coffee or black pepper. Larger roaches produce dark, cylindrical droppings with blunt ends and ridges down the side.

Cockroaches leave feces wherever they dwell and sleep. Cockroach droppings are a powerful attractant and cause other cockroaches to come. The pheromone is detected by humans as a lingering musty odor.

How Does Cockroach Feces Affect My Home?

Cockroaches are omnivores, and the pests will eat whatever is available. Garbage, sewage, carrion, and crumbs are all acceptable food options. As a result of this, cockroach digestive systems keep disease microbes from everything they consume. These germs then go from the cockroaches’ body to your countertops and drawers by their feces.

Cockroaches, like other insects, have little regard for personal cleanliness. The vermin defecate wherever they eat. Cockroach feces pollute pantries, kitchen surfaces, and poorly sealed food containers and may distribute pathogenic germs to people. These germs are known for increasing the severity of asthma.

The best way to control cockroach feces is by reducing the cockroaches’ access to food and water. Sanitation will also help remove fecal matter, but it is impossible to eradicate all droppings.

Why Should You Look For Cockroach Droppings?

Cockroach droppings have been linked to an increase in asthma attacks and severity, and the EPA considers them as asthma triggers. Cockroach feces also give a telling musty odor to an infestation. Aside from that, do you want your children or pets exposed to roach dung?

If you still need a reason to search your home for droppings, consider this: ignoring it will bring more roaches. In roach feces, there is an aggregation pheromone that attracts other roaches together.

Pest management experts take advantage of this information. They deploy bait in strategic locations near roach droppings in order to entice more roaches to come into contact with the poison. The more they respond to other roaches’ natural attractant pheromone, the more they die.

How To Properly Clean Up Cockroach Droppings

Cleaning up after a roach infestation can be difficult because of the pheromone that attracts other cockroaches to the droppings. In order to minimize the attraction, use a commercial cleaner that breaks down the pheromone or clean with a solution of bleach and water (one part bleach to nine parts water). Always test any cleaning product on an inconspicuous spot before using.

Wear gloves and a mask when cleaning up cockroach droppings. Carefully sweep or vacuum the droppings, then dispose of the waste in a sealed garbage bag. Wipe down the area with a disinfectant to remove any traces of feces.

To keep cockroaches at bay make sure to seal any cracks in your walls, cupboards, and drawers with silicone. You should also use cockroach traps, bait, and even borax to kill them.

Where To Look For Cockroach Poop

Cockroaches literally poop everywhere they go. They don’t have a specific bathroom like humans do, but there are certain places where they are more likely to poop. They frequently poop near their food sources and nesting or congregation areas. Unfortunately, since their food sources are often near (or in) yours, your food can become contaminated.

Cockroach feces can be found in nearly every area where cockroaches are spotted. If you spot a roach scurrying away, look for droppings nearby.

Common places to find cockroach droppings include:

  • In corners of rooms
  • Along baseboards
  • On high surfaces, cabinets, doors, and other tall objects
  • Drawers, pantries, closets, cabinets, and other food storage locations
  • Children’s playpens and toy chests
  • Refrigerators, stoves, washers, dryers, and sinks are all examples of appliances that are often hidden from view beneath and behind them
  • Any cracks or openings in the floors or walls
  • With organic storage materials, such as cardboard boxes and papers (particularly in storage rooms)


Cockroach droppings are a major health concern and should not be taken lightly. Not only can they trigger asthma attacks, but they also attract more cockroaches to the area.

In order to properly clean up after an infestation, you need to use a commercial cleaner or a bleach and water solution. Be sure to wear gloves and a mask when cleaning up droppings. Dispose of the waste in a sealed garbage bag and wipe down the area with a disinfectant. You can also use cockroach traps, bait, and borax to kill them.

Inspect your home for cockroaches and their droppings regularly to keep them at bay.

If you’re still not convinced that cockroach droppings are a health hazard, read on. In addition to asthma attacks, cockroach feces can cause food poisoning and other diseases. The Centers for Disease Control and Prevention (CDC) even considers them as potential vectors of human pathogens.

And if all of that isn’t enough to scare you away, consider this: cockroach droppings can last for years. They don’t decompose like human feces and can be a breeding ground for bacteria. So not only are they a health hazard, but they can also contaminate your environment long after the cockroaches have been eliminated.
