Ants Can’t Die in the Microwave: This Is Their Secret

Everybody hates the fact that now and then ants appear to ruin your mood. Nobody has time to deal with an ant infestation, especially with electronic devices you need to use every day.

Such is the case with the microwave. Ants infest it for many reasons but truth is, you need to get them out as soon as possible. Even if you use it with some of them in, they will not die.

Ants can survive the microwave wavelengths because they are too small to be affected by them. Ants are small creatures who do not contain enough water in their bodies when compared to others. This simple aspect prevents the microwave from being able to “cook” ants alive.

Why Am I Getting Ants in My Microwave?

Ants infest microwaves in search of food for their colony. When microwaves cook food, the heat waves may cause some food to pop, this leaves little crumbs here and there. What happens, is that ants love these crumbs of food, because it serves as provisions for ants.

If you don’t cover your plate while heating it in the microwave, there are big changes for that to happen.

Another reason why ants infest microwaves is because of smell, when you heat food in the microwave it releases scent in form of vapor. If you don’t clean your microwave regularly, that vapor sticks to the microwave walls thus creating a strong scent that will attract many ants to it.

Can Ants Damage a Microwave?

Microwaves can become quite damaged by ants, even if you don’t see them. Ants can infest the electronic boards of your microwave and use them to their benefit. You won’t be able to reach them or kill them if they infest your microwave from the inside out.

If that happens, you will only be able to get rid of them by taking your microwave to a service repair center. This is why it’s important to deal with ants right away. Even if you see just a small ant, be watchful to where did it come from.

Can Ants Provoke a Fire Hazard in My Microwave?

This is one of the biggest problems with ants, if they infest your microwave circuit board, they can die in there, and dead ants attract more ants. The cumulative of ants in a circuit board may generate unwanted heat and may provoke a fire hazard.

Can Ants Provoke a Shock Hazard in My Microwave?

Another thing ants may provoke in a microwave is a shocking hazard, although not so common as a fire hazard, the accumulation of dead ants in the microwave power supply board, may bridge electricity from one place to another.

Ants are definitely not welcome near a microwave, and you should be vigilant about their presence.

Do I Need to Move My Microwave to Other Location Due to Ants?

Sometimes when you are dealing with ants, if the infestation is not on the microwave per se, it can be a good idea to move it elsewhere temporarily, to clear the area out.

When moving your microwave to another area while clearing the main infestation spot, be sure to check your microwave for ants’ presence, so you won’t end up leaking the infestation even further.

If the infestation is definitely on your microwave, there is no need to move it out. You can treat it right there on the spot. If it makes sense to move it out so ants won’t infest other electronics nearby, then go ahead and do it.

Should I Buy Another Microwave?

Can I Use My Microwave on the Same Day I Eliminated the Ants?

As long as you don’t notice any ants presence in your microwave, you can use it normally as you would. If you decide to use pesticides on your microwave, it might be better if you leave it for a couple of hours or a day to dissipate the residues and then clean it very well before using it.

Don’t forget to keep an eye on it for a couple of days, to see if your initial intervention was enough. Happy microwaving!
