How to Get Roaches Out of Microwave: 5-Step Guide

Roach infestation is the last thing you want in your microwave. They can damage your microwave as well as cause health problems.

How to get roaches out of the microwave?

Use a cleaning agent containing bleach and spray it inside the microwave. After that, clean the solution and spray the insect-killing solution inside the microwave. Let the insect killer solution sit for a while and clean the interior of the microwave.

That’s not all. There’s more to these steps that need to be elaborated. 

Let’s get going!

Why Do Cockroaches Live in Microwaves?

Microwaves offer an ideal shelter for cockroaches. It mostly remains undisturbed and stays dark and warm. Plus, microwaves provide easy access to food and water.

Rarely cleaned microwaves from grease and food residues that provide adequate support for cockroach infestation. 

Microwaves that are not used for quite some time give the roaches opportunities to lay eggs. There are parts of the microwave that still remain cool while used for cooking. So every time you heat up the microwave, the roaches flee to the cool spots.

Can Cockroaches Damage Microwaves?

Cockroach infestation inside the microwave for a long time can damage the microwave.

Eggs, feces, and dead cockroaches can damage the internal wiring of the microwave. 

Not only that but they can also damage the wiring of the microwave. If a microwave is left unused for a long time, the cockroaches can gnaw on wires. This can eventually cause the microwave to stop functioning.

Cockroaches can be responsible for electrical short circuits which can eventually lead to fire hazards. Damaged wiring can emit spark, which, in contact with flammable objects, can cause a fire.

So you should always be careful about a cockroach infestation in your microwave.

How Do I Get Rid Of Roaches From My Microwave?

You need to immediately take steps to halt the spread of cockroaches in your microwave. With proper measurements, you can easily eliminate all the cockroaches inside your microwave.

Here’s how you can get rid of roaches from your microwave:

Step 1: Disassemble The Microwave

The very first thing you need to do is to disassemble all removable components of the microwave. Make sure to take out the components that are sensitive to chemicals. Keep them somewhere safe.

Make sure to unplug the microwave first before proceeding to disassemble the components.

Step 2: Spray Bleach Disinfectant

Use a cleaning agent containing bleach and spray it inside the microwave. You can also use a solution of water with 2 tablespoons of white vinegar.

Spray all the corners and walls of the microwave and let the solution sit for 5 to 10 minutes. Close the door of the microwave after that for a few minutes. This will trap the steam inside and help loosen the grimes and greases.

There are many available brands of cleaning agents containing bleach in the market. I have personally tried some of them to check which cleaner works the best. Here’s my recommendation-


Hope the cleaners will come in help while executing this task.

Take a clean cloth and wipe off the solution after that. Avoid using abrasive cleaners. 

Step 3: Apply Insect-Killing Solution

For this step, you need to take your microwave outside your house. If you have a backyard, sit the microwave there.

Spray anti-roach solution inside the microwave in high volume and leave it for an hour. Let the insecticide sit inside the microwave and kill the cockroaches inside.

Keep the microwave and leave it somewhere remote, away from children.

Do not carry out this operation inside your house by any means. Regular insecticides contain chemical components that are harmful to the human body. Insecticides like Raid can be bad for the skin and respiratory system as Raid is highly toxic 

Step 4: Remove Dead Cockroaches

There will be dead cockroaches lying around inside the microwave. Get rid of them and spray the cleaning solution one more time inside the microwave. Let the cleaning agent sit inside for half an hour.

Step 5: Final Cleaning

Use a clean cloth to clean the interior walls of the microwave. Spray the bleach cleaning solution one final time and clean it off with a clean cloth. That should do it.

Your microwave should be free from any remaining cockroaches. Thanks to the final cleaning, any remaining germs, and bacteria from the dead cockroaches are cleaned.

Perform the task outside, or else, it will make your house smell like bleach.

How Do I Keep Cockroaches Away from Microwaves?

Once you get the roaches out of the microwave, your job is only half done. You’ll have to take preventative measures to avoid any future visits from the roaches.

Never leave any food spills after cooking in the microwave. Make sure to wipe the microwave clean every time you cook anything in it. Remember, cockroaches avoid clean places.

Some people have a bad habit of leaving uneaten food inside the microwave. This will only invite more cockroaches to take shelter inside the microwave. Instead, throw uneaten food in the bin or keep it in the refrigerator.

Cockroaches won’t hang around if you apply lemon slices or peppermint oil near your microwave. You can also leave cheap wine inside the microwave. It’s a great roach trap as drinking cheap wine will kill the cockroaches.

Keep your microwave closed if you’re not using it.

These simple measures can save your microwave from cockroach infestation in the future. Try deep cleaning the microwave every once in a while to keep it in top shape.


Question: Is Raid a toxic insecticide?

Answer: Yes, Raid is very much toxic and contains harmful chemicals for the human body. One must follow safety measures before spraying Raid in the room.

Question: Can I spray Raid in a microwave?

Answer: Spraying Raid inside the microwave is not a wise thing to do. Application of Raid can cause corrosion and an electrical short circuit inside your microwave. 

Question: Does soap kill cockroaches?

Answer: Cockroaches can die from soap water. Soap can melt a cockroaches’ protective coating and block its spiracles. The roach won’t be able to breathe and die eventually.


You have learned how to get roaches out of the microwave. Make sure that you follow the entire procedure outside your house. Insecticides contain harmful residue that can cause severe health issues. So be careful.
