How to Get Rid of Ants in the Microwave

One of the main reasons why ants invade homes is that they are looking for food in order to keep the entire colony alive. No other part of your abode is brimming with grub more than the kitchen. Just about anything that comes into contact with food can attract ants, and that includes the microwave.

To get rid of ants in the microwave, first rid the kitchen appliance of grease and food particles. Afterward, kill ants by wiping down the interiors with soapy water. Ants can be exterminated, too, with baking soda and sugar. It’s also a good idea to erase any ant trails to prevent a reinfestation.

Whether dead or alive, ants can easily turn a microwave meal from delicious to atrocious!

Below, you will come across some foolproof tips and tricks on how to get rid of ants in the microwave effectively.

But before anything else, let’s give an answer to this pressing question…

Can a Microwave Kill Ants?

In general, microwaving ants for a few seconds is not enough to kill them. It can take a few minutes before ants die in the microwave, as their tiny bodies can take a while to heat up. Coming into contact with food or scraps of food hot enough will kill ants in the microwave.

It’s true that ants survived whatever it is that killed the dinosaurs as well as wars that wiped out millions of people from the face of the planet. However, it isn’t true that ants can survive the microwave.

Here’s the reason why your microwave failed to kill ants when you tried to nuke them once: you didn’t microwave ants long enough. But had you microwaved ants for a few more minutes, you would realize that they are not at all that invincible within the confines of a microwave — you would have surely heard small popping sounds.

The following are why ants do not die in a microwave right away:

  • They have very little water in them — microwaves work by causing water molecules to rub against each other.
  • Because they are very small, ants tend to lose heat very quickly.
  • Chitin, the material that makes up their exoskeletons, can shield them from high temperatures.
  • Some places in a microwave are cooler than the rest.

The bottom line is that you can kill ants by microwaving them for a longer period of time. Or you can follow the steps on killing ants in the microwave below and save electricity — so don’t stop reading now!

What Can You Do to Kill Ants in Your Microwave?

A mixture of dish soap and water can kill ants in the microwave. Soapy water also gets rid of the trail of chemicals ants leave behind for the rest to be able to find the microwave. A mixture of baking soda and sugar can kill ants in the microwave and also in the nest, from the queen to its babies.

You can leave the microwave running for a few minutes to kill the ants in it. However, this is a complete waste of electricity and may damage your microwave, too — it’s a terrible idea to run a microwave empty.

It’s a good thing that there is a quicker and safer way to rid your microwave of ants, and it’s by wiping down its interiors with a sponge dipped in soapy water. This works effectively as dish soap can suffocate ants until they breathe their last. But before you give this solution a try, remember these two very important things:

  • Unplug the microwave beforehand.
  • Wring out excess soapy water from the sponge.

While it’s true that ants in the microwave (and elsewhere in your kitchen) are a nuisance, it’s still a must that you maintain your safety and that of your loved ones. It’s also a good idea to keep your microwave out of harm’s way.

And that is why you should bear in mind the two safety tips mentioned above.

How to Use Ant Dust

One of the most popular commercially sold insect killers is ant dust. Despite what it’s called, the product is highly effective against many insects other than ants.

Some of them include bees, centipedes, cockroaches, ground beetles, millipedes, silverfish, slugs, spiders, ticks and wasps. Of course, it can kill all types of ants, from carpenter ants to fire ants.

Deltamethrin — this is the active ingredient of ant dust.

According to a report by the National Pesticide Information Center (NPIC), deltamethrin is low in toxicity when touched or breathed in.

On the other hand, it’s low to moderately toxic if eaten.

So, in other words, caution must be practiced when using ant dust to keep the microwave off-limits to ants.

Ant dust comes in a bottle whose cap allows it to be used as a shaker. For ridding the microwave of ants, a small amount of the product may be placed at the back. It may also be applied in areas that give those ants access to the kitchen.

Most ant dust brands are waterproof and can work for up to 8 long months.

Best Natural Ant Baits

And now, here are four things that you may try to free your microwave of ants:

Dish soap and water mixture

Wiping down the interiors of your microwave with soapy water is like hitting two birds with one stone: it lets you kill ants and get rid of grease and food particles, too.

To make an ant-zapping solution, combine one part dish soap and two parts water in a bowl. Mix, dip a sponge in it, wring out excess and wipe away those ants and anything else that’s not supposed to linger in your microwave. Use a damp kitchen towel to remove excess soapy water and allow the microwave to air dry.

Baking soda and sugar

You can kill ants not only in your microwave but also those that are waiting in the nest for the meals to arrive. It’s none other than by making a homemade ant killer using baking soda and sugar.

Baking soda can kill ants by altering the pH levels in their tiny bodies. But because ants know that baking soda can kill them, they will do anything and everything necessary to avoid it at all costs.

This is when the importance of adding sugar, which is something that ants find irresistible, to baking soda comes in.

Don’t just add any sugar — use confectioners’ sugar, the kind that’s fine powder.

All you have to do is mix equal parts of baking soda and confectioners’ sugar. Transfer to a small dish and leave it in the microwave to allow the all-natural insecticide to do its job.

Corn syrup and baking soda

There’s no denying that ants love corn syrup. On the other hand, baking soda can kill them. And that is why combining the said ingredients allows for the creation of something that can attract ants and exterminate them afterward.

All you need to do is combine equal parts of corn syrup and baking soda. Place small dots of the mixture on a sheet of wax paper and cut them into small sections and place them around the microwave.

Peanut butter and baking soda

Other than corn syrup, you can also use peanut butter. Of course, peanut butter alone won’t rid your microwave of those annoying ants — you need to add baking soda to it, which is lethal to ants and many other small insects.

As expected, simply combine peanut butter and baking soda using a 1:1 ratio. Place dollops of the mixture on small pieces of wax paper and leave them in problem areas until those ants bother you no more.

ant and lemon

Does lemon juice kill ants?

Lemon juice, unfortunately, does not kill ants. However, it’s very good at repelling them and other small insects, including many garden pests. Other than lemon juice, lemon rind also works as an effective ant repellent.

Besides driving away ants, lemon juice and lemon rind also help deodorize the kitchen and clean and disinfect all sorts of surfaces.
