Regular Cleaning:

It’s not a bad thing to admit that you cannot handle the cleaning of your microwave.

Many people can’t do that due to time limits or another such thing. So, what you can do is schedule a deep cleaning every year.

You can either do it yourself by removing all the removable parts like the plate etc. or just send it to the technician.

Trying Vinegar:

Moving onto a real solution, you can just use vinegar to solve the problem. This trick is very popular, and you can easily find the tutorial for it on YouTube.

After some time, usually ten minutes per heating, the creeps will crawl out of their hides. Kill them as soon as they come out. It might take you at least 3 to 4 rotations of 10 minutes of heating the solution to make sure every roach has crawled out of its hidey-hole.

To make it more effective, grab a piece of cloth, dip it in the solution, and wipe everything down with it to reach everywhere.

Use Boric Acid:

Boric acid is another deterrent that you can use to achieve the same result. It is, after all, harmless to humans but proven to be very deadly to these insects upon ingestion.

You can get these in the form of either a borax laundry booster or a roach tablet. Either will work.

Peppermint Oil:

Peppermint oil is another natural disinfectant that can be safely applied on the interior as well as the surroundings of the oven.


Another natural disinfectant that can be pretty helpful. The thing with these natural disinfectants is that if you are concerned about the commercial produces, chemical-filled disinfectants, these natural ones are a better alternative, but that will not guarantee you a hundred percent result.

Harmless Traps:

You might be surprised to learn that just like a mousetrap, a cockroach trap also exists. You can quickly get a bunch of these non-toxic traps and place them around your oven to catch the pests. After they are caught, kill them swiftly.

Disinfectant Products:

When all the other methods fail, head to the nearest store, and grab a good disinfectant or pest killer from a reputable company.

Apply the disinfectant in the interior of your oven, and wipe everywhere else with a cloth. But make sure that the product you are using is accurate, safe for you and your family. You can also get some spray.

The process is straightforward. Remove all the removable parts and apply disinfectant.

Leave it there for at least 10 minutes, and then remove the dead insects. After that, wipe the interior thoroughly, along with the microwave plate, wires, and other places.

WHO has clearly stated that cockroaches are “unhygienic scavengers in human settlements.” But it’s not just the health and hygiene problems.

More accurately, the fear, the phobia of roaches, has been deeply ingrained in the human brain.

Even if we ignore everything else, that phobia will not let us do so. But when you find these pests in places where you keep your food, it becomes more urgent to get rid of them.

So whenever you notice even a little-sized roach, don’t hesitate, grab everything you need, and get to work immediately.
