If you’re like most people, you probably don’t enjoy finding tiny insects in your food. Gnats are especially pesky because they seem to be everywhere, including in your microwave.

While it’s not pleasant to think about, these bugs can actually lay eggs in your food. Gross! Luckily, there are a few things you can do to get rid of gnats in microwave and keep them from coming back.

How Long Can A Gnat Survive In A Microwave?

Many folks who have an infestation wonder why gnats don’t perish in the microwave. Even though the microwave is being used to heat food, there are 4-5 portions that stay cool.

A magnetron produces microwave radiation. This is on one of the oven’s sides. The inside of the microwave is lined with metal, which reflects radiation to the center. At the same time, the microwave agitates the water molecules, causing vibration and heat to be produced.

As previously stated, not every portion of the microwave warms up. Gnats like those who keep cool. As a result, if the microwave is used, they will retreat to the chilly regions until it is safe.

While this is one method gnats survive in a microwave, they also survive because their bodies contain extremely few water molecules. GN survive the heating procedure because there is little water in their system to kill them.

These creatures could theoretically survive in a microwave eternally. After all, if they can withstand a nuclear explosion, microwave radiation is unlikely to inflict long-term harm.

Gnats are unlikely to explode in a microwave. As previously stated, neither the microwave’s heat nor radiation levels are strong enough to kill a gnat.

Gnats, on the other hand, might explode in a microwave after consuming a toxic solution containing sodium bicarbonate (baking powder.)

Now that we have learned the basics about gnats in the microwave let us take a look at how to get rid of gnats in microwave.

Deep Clean

If you don’t want to use the microwave when gnats are there, thoroughly clean it to eliminate any oil and spills that gnats are drawn to. This will compel them to seek nourishment elsewhere.

Microwaves are simple to clean with common home cleaning supplies. Gnat Cockrs despise the fragrance of lemon thus, using lemon-scented cleaning products is preferable.

Importantly, avoid using bleach since it might harm the plastic inside of the device and cause it to perform inefficiently. To clean the interior:

  • 1 cup of water, lemon slices, and white vinegar
  • Place the bowl in the microwave for several minutes on the highest power setting. You want the mixture to come to a boil and the device to start steaming.
  • Allow it to cool for 5 minutes before removing the bowl and wiping the inside with a towel.

To clean the glass tray, remove it from the microwave and place it in a washing-up basin with hot water and dish detergent.

  • Allow it to soak for an hour.
  • Rinse away any residual oil and grime.
  • Wipe it clean with a grease-cutting spray.
  • Replace it in the microwave after cleaning the whole appliance.
  • Make a mix of water and baking soda to clean the door.
  • Completely clean the door, including the sides, edges, and seals.
  • Make a 50/50 combination of water and white vinegar for the glass window. Clean with a clean sponge, then rinse.
  • After that, spray a grease-cutting cleaner all over the door.
  • Once the microwave is clear of gnat-attracting food spills, wipe it down each time you use it to maintain it clean and debris-free.

Prep Microwave

Turn off your microwave. This keeps you from being electrocuted when cleaning and moving about in your microwave. Protective rubber gloves should be used during the cleaning procedure.

Remove any revolving plates from your microwave and gently lay them aside. Examine the area behind and under the microwave for rotting food or crumbs that may be attracting insects.

Bug Removal

If the bugs are dead, use a vacuum to get them out of the microwave. If the bugs are live, non-flying bugs, and there aren’t a lot of them in the microwave, sweep them into a plastic bag, close it up, and dispose of them outdoors away from your house.

Bug bombs (insect foggers) may help remove contamination, but they might also cause the bugs to hide deeper in your microwave. Bug bombs may be harmful to people and pets if handled wrong, so read the label before using one.

If the insect contamination issue is widespread and not limited to your microwave, it is recommended to replace it and contact an exterminator.

Microwave Cleaning

Vacuum your kitchen counters and any microwave surfaces. Start by scrubbing your microwave with hot, soapy water.

To avoid scratching the sides and surfaces of your microwave, especially the rotating plate and buttons, use a soft pad scrubber or a washcloth. After cleaning the microwave fully, discard the scrubbing pad. To disinfect your microwave, use normal household bleach.

Do not spray chemicals straight into your microwave. Instead, spray the bleach onto a towel and wipe it clean. This will prevent water or chemicals from entering the microwave’s operational controls. Replace the rotating plate in your microwave after thoroughly cleaning it.

Using the same process of water and soap, then bleach, clean behind and beneath your microwave. If you believe the insect issue has been remedied, reconnect your microwave.

Maintaining a bug-free kitchen can keep pests out of your microwave. Clean up any spills or crumbs right away to avoid attracting pests to your kitchen. Clean out drawers and cabinets and double-check that food is completely sealed.

If you wish to open windows in your house, install window screens. Remember to clean behind and beneath your microwave (or on top if you have an over-the-range microwave) at least once a week.


Hopefully, now you know the ways you can prevent the gnats from entering the microwave as well as get rid of them.
