Cockroaches in Dishwasher How to Get Rid Of Them?

The kitchen, often considered the heart of the home, is a place where culinary magic happens. But what happens when an unexpected guest, more precisely a cockroach, decides to join the party? The discovery of a cockroach in the dishwasher can turn the joy of cooking and cleaning into a moment of unease and concern.

Why Do Cockroaches Enter Dishwashers?

Cockroaches are resourceful creatures known for their ability to adapt and survive in various environments. While the idea of finding one inside your dishwasher might be unsettling, there are reasons behind their intrusion.

  1. Food Residue: Cockroaches are attracted to food particles and residue. Dishwashers, despite their cleaning capabilities, might have leftover food scraps that become appealing to these pests.
  2. Warmth and Moisture: Cockroaches are drawn to warm and humid environments. The moist, warm environment inside a dishwasher can be inviting to them, especially if there’s a water leak.
  3. Darkness and Shelter: Dishwashers provide a dark and sheltered space, offering cockroaches a safe haven to hide and reproduce.

Risks Associated with Cockroaches in Dishwashers:

The presence of cockroaches in dishwashers can pose several risks, both in terms of health and sanitation.

  1. Contamination of Dishes: Cockroaches can carry bacteria, pathogens, and allergens on their bodies. If they come into contact with dishes, utensils, or glassware, these contaminants can transfer onto items that you use for eating and drinking.
  2. Food Safety Concerns: Cockroaches crawling around your dishwasher can lead to contamination of clean dishes, rendering them unsafe for use.
  3. Health Hazards: Cockroach allergens can trigger allergic reactions, especially in individuals who are sensitive. Moreover, their presence might exacerbate conditions such as asthma.
  4. Spread of Disease: While cockroaches are not primary vectors of diseases, their presence in your kitchen can still contribute to an unsanitary environment.

How to Get Roaches Out Of Dishwasher Door?

Dealing with cockroaches in unexpected places like your dishwasher door can be quite unsettling. However, you can take several steps to effectively remove them and prevent their return. Here’s a step-by-step guide on how to get roaches out of your dishwasher door:

Safety Precautions

Before you begin, ensure you’re wearing gloves and protective clothing to minimize direct contact with the cockroaches. Additionally, gather the necessary cleaning supplies, such as a vacuum cleaner, soap, water, and a brush.

Empty the Dishwasher

Empty the dishwasher of all dishes, utensils, and any items stored inside. This will give you better access to the door and the areas where cockroaches might be hiding.


Carefully inspect the dishwasher door, paying close attention to the rubber gasket, crevices, and any gaps. Cockroaches can squeeze into tight spaces, so be thorough in your examination.


Use a vacuum cleaner with a nozzle attachment to gently vacuum any visible cockroaches. Start from the top of the door and work your way down. Make sure to vacuum around the rubber gasket and other nooks and crannies.

Soap and Water Solution

Prepare a solution of warm water and dish soap in a bowl. Dip a brush or sponge into the soapy water and use it to clean the door, paying special attention to areas where you suspect cockroaches were hiding.

Wipe Down

Wipe down the entire dishwasher door with the soapy solution. This will not only clean the door but also eliminate any scent trails that cockroaches might have left behind, making the area less attractive to them.

Seal Entry Points

Inspect the area around the dishwasher for any gaps or openings that cockroaches might have used to enter. Seal these gaps with caulk or another appropriate sealing material to prevent future infestations.

Regular Cleaning Routine

Maintain a regular cleaning routine for your kitchen, including the dishwasher. Clean up food crumbs, spills, and other debris promptly to minimize potential food sources for cockroaches.

Natural Repellents

Consider using natural cockroach repellents, such as a mixture of water and essential oils like peppermint, eucalyptus, or citrus. Spray this mixture around the dishwasher area to discourage cockroaches from returning.

Pest Control Professionals

If you continue to experience cockroach issues despite your efforts, it might be wise to consult professional pest control services. They can assess the situation, provide effective treatments, and offer guidance on long-term prevention.

Remember that consistency is key to keeping cockroaches at bay. Regular cleaning, sealing entry points, and maintaining a sanitary kitchen environment will greatly reduce the chances of cockroach infestations in the future.


In conclusion, the appearance of a cockroach in your dishwasher is certainly unwelcome, but it’s a situation that can be managed with the right steps. By understanding the reasons behind their intrusion, the risks they pose, and implementing preventive measures, you can maintain a clean, safe, and pest-free kitchen environment. Remember, a proactive approach to sanitation and maintenance is key to keeping unwanted guests out of your culinary haven.
