Best Practices to Get Rid Of Roaches in Microwave 

After noticing roaches in your microwave, you may want to eliminate them immediately. But the process requires total devotion. If you use the wrong procedure, the probability is that you’ll destroy your microwave, and it may start a fire. Below are the five best methods to eliminate these annoying insects:

1. Dust Trap

After removing food and dirt deposits from the microwave, cockroaches still leaving or that have come back may want to leave to find food. As such, dust traps can also poison roaches that visit them.

Though you can use it as a direct trap on roaches, it’s more effective if you smear it in the surrounding areas. But, you may avoid using the trap inside the microwave; therefore, move the appliance to a secure, private place and surround it with the powdered trap mixture. Ensure you spray the powder near the door to stop the roaches from fleeing.

When roaches get out looking for food, they become trapped and poison themselves. It’s a technique that works perfectly on huge swarms. Since there are dead roaches, other roaches eat the dead ones and eventually they will consume the poison, which will kill them.

2. Deep Clean

If you’re not ready to encounter a microwave full of cockroaches, clean it comprehensively to eradicate all the remaining food particles and grease that attract the cockroaches. Due to that, the insects will need to look for food elsewhere.

It’s best to clean the microwaves using ordinary house cleaning detergents. But the lemon-fragrance ones are desirable since most pests, cockroaches included, hate the smell.

Most importantly, avoid using bleach because it can harm the inner plastics and make the gear slightly ineffective.

To clean the interior:

  • Mix one cup of water with white vinegar and lemon slices.
  • Put the cup inside the microwave and switch it on for a few minutes at maximum temperature. The mixture will boil, and the microwave will steam up.
  • Let the appliance cool for five minutes, then remove the container and wipe its interior using a fabric.

Cleaning the glass tray:

  • Take out the microwave tray and put it in a washing bowl containing hot water and detergent.
  • Let it soak for one hour.
  • Brush all the residual grease and dirt, then rinse.
  • Spray it using a grease-cutting spray and wipe it out.
  • Return to the microwave after cleaning the whole equipment.

Cleaning the door:

  • Make water and baking soda solution.
  • Clean the whole door, focusing on the edges, sides, and seals.
  • For the glass, mix a half portion of water and half a portion of vinegar. Use a clean sponge to scrub, then rinse.
  • Finally, spray the whole door using a grease-cutting cleaner.

After the microwave is clean and doesn’t invite roaches, wipe it immediately, you use it to retain it clean without debris.

3. Commercial Disinfectants

Using commercial disinfectants is an efficient way to eradicate roaches from the microwave. But using disinfectants is also not safe. Even by cleaning the area thoroughly, you may leave some chemical drops that can get in your food when using the microwave.

When using a disinfectant, ensure you clean the microwave’s insides carefully after spraying. It’s advisable to move the microwave in an open place so the cockroaches from the microwave won’t hide in your kitchen. You can also use gel baits from stores to trap and kill roaches.

4. Cold Temperatures

If you’re on a budget and notice a few cockroaches, take your microwave to a cold place and entice them out. And if you reside in a cold area, you can bring your microwave to a garage or a cabin. You can put it outside entirely if you provide proper protection from external elements like rain and fog.

For more, follow these instructions:

  • Remove the power plug from your microwave.
  • Cover the appliance using a plastic bag, making sure to firmly close the bag to prevent water and air from penetrating.
  • Ensure the plastic wrapper has ample holes where the roaches can escape.
  • Put the microwave in a cold place like a garage or a cabin.
  • Let the microwave stay there between four to five days to allow the cockroaches to leave.

The right temperature that makes it effective is from 1.6 degrees Celsius to 10 degrees Celsius. Similarly, any region with a cooler temperature than the above will destroy the cockroaches.

5. Professional Help

There are many eradication methods that you can use by yourself, but if the spread is expansive, you may need professional help. Though you can disassemble the appliance and remove the invasion physically, you will most likely spoil your microwave.

So, it’s advisable to look for a pest control expert. Professionals can assess roach spreads and suggest the most viable solution. You can also get the most uncomplicated and harmless means to operate your electrical apparatus.

Can You Bug Bomb A Microwave?

Bug bombs are also called total release foggers or defoggers and are aerosol releasing pesticides. These aerosol chemicals are for fumigation, and they kill cockroaches. Bug bombs are used in huge spaces to kill cockroaches and other insects swarms. They kill most cockroaches except those that are hiding far.

Furthermore, research by professors at Envista Forensics established that bug bombs contain water particles. Observing a fogging technique, if water particles drop on electronics, they cause:

  • Deterioration
  • Corrosion and unprotected circuit boards
  • Electronic failure

Bug bombs contain:

  • Chloride dioxide
  • Ethylene bromide
  • Methyl bromide

These chemicals cause the microwave’s electronic component to fail. Again, they are combustible; hence they might cause a fire once the gear is switched on and operating.

Likewise, bug bombs might cause cockroaches to hide further inside the appliance, making them more challenging to eliminate.

How Long Can A Cockroach Survive In A Microwave?

Literally, cockroaches can live in the microwave forever. And since they can survive a nuclear explosion, microwave radiation can’t cause them any harm.

How to Get Roaches Out of MicrowaveMost people with cockroach invasion wonder what the answer to this question might be: Why don’t roaches die in the microwave? The microwave has four to five sections that never heat, even when using it for cooking.

Basically, microwaves produce radiation from a magnetron. It is situated on one part of the microwave. Metals outline the microwave’s inner parts that produce radiation in the middle. Subsequently, the microwave jiggles the water molecules, producing heat and vibration.

The reality is that not every section of the microwave gets hot. Some remain cool, where roaches find refuge. Therefore, they’ll run to the cool parts where it’s safe when you’re using the microwave.

Whereas this is among the ways that cockroaches live in the microwave, they also don’t die since they have fewer water molecules in them. Cockroaches remain unhurt when cooking with the microwave because they don’t have sufficient water in their body to destroy them.

  1. Ensure you wear all the required safety equipment when cleaning. The gear includes gloves when cleaning using chemicals or scrubbing the microwave.
  2. Wear a mask to prevent you from breathing any gases discharged when cleaning.
  3. Don’t switch the microwave while the power is on. Switch off the power until you’re done cleaning.
  4. Check the chemicals you’re using to clean your gear because they may indirectly affect your food.
