Getting rid of indianmeal moth

Interesting idea, I seem to recall that they get killed by temperatures above the 50-60° range.

You need to do that when buying them, and I wouldn’t trust the typical flimsy container they’re sold in to handle that (and without releasing anything noxious into the food). So you still need a container for storage.

Just what do you do with all that popcorn and puffed rice?

Seriuosly, can you actually heat it high enough to kill the buggers? Or is it more for your peace of mind?

Yes, the thought alone is revulsive. Obviously mileages vary.
And I refuse think about what might apply in Asian countries.

As for porcelain, I guess GM meant ceramic or perhaps stoneware, the material e.g. plates are made of. Reasonably sturdy (made), not delicate like actual porcelain which you can break with a stern look.

Yes, this stuff is far superior for presentation. The same applies to glass wine glasses.
But presentation is no criterion for storage containers.

As usual the mods suck. Instead of calming the situation they’re the biggest shit-stirrers.

I don’t usually buy popping corn so don’t know how that would be affected in the microwave but the rice is unchanged, as far as I can see, after a zap in the microwave.

You don’t need to heat the product itself up to a high temperature but it wouldn’t take much heating to heat up and kill any eggs or lava in there. If you’re worried about affecting the product, I’ve read that you can store stuff like that in the freezer for 24 hrs and it does the same job.

Kill by freezing takes days, apparently. Which is why a zapping, a matter of minutes, is interesting.

Interesting, but a waste of time:

Small insects can survive unharmed in a microwave oven.

Larger insects get cooked.

Microwave ovens work by creating standing waves of microwaves that concentrate energy in their peaks. But this also creates regions where the waves cancel out by destructive interference, that do not get significantly heated. This is why when you warm something up in a microwave you often get uneven heating with hot and cold spots and it is necessary to stir or let the food stand for a while so the uneven heating can be evened out.

A small insect is small enough to fit inside one of these cold “safe” spots.

Well, had no more issues with moths or any other bugs since. Hey, maybe it’s all down to the storage jars after all… :laughing:

Thanks. Yet, that’s why the carrier plate rotates. And why you should stir the goods.

Yes, Shirley, it’s the same here, containers it is, just like the ancestors did. With only a few exceptions, like wild rice or some Asian spices and condiments.

With that said, zapping the rice burns it.

Now I have an image of small bugs dodging microwaves mission-impossible style as the container is rotated around the microwave.

How so?

There are many food stuffs which, after cooking from the fridge, can be piping hot in some places and icy-cold in others.

It’s why one should never warm baby formula in a microwave but should use a water bath instead.

It just does, probably goes above 100°.
The same kind of burn you get when stuff burns at the bottom of a pot or pan.

You know that microwaves only agitate the water molecules to heat them, right? Dried goods have no water in them (that’s the point so they store for longer). No water, no cook. Same reason that the handles of stuff holding the food never heats up in the microwave, unless it’s in contact with the cooking food or its steam, obvs.

Besides, I’ve never noticed any burning smell or change to the taste.

You contradict yourself. Why zap the rice if it supposedly doesn’t absorb the energy?

And of course the resulting temperature is a function of the amount of energy supplied. Longer zapping results in higher temperature.

I’m not zapping the rice. I’m zapping the bugs/lava/eggs which have a level of water content :wink:

EDIT: I was only contributing to the thread originally to offer help and a solution, which I have found works for me but, hey, you do you. :+1:t2:

Feel free to explain then how zapping burns dry rice. Dry isn’t zero water content. Plus, that particular wavelength isn’t absorbed by water molecules only.

Eh? Why do I have to explain your assumption to you?

You said:

and

Maybe you need to explain it to yourself? I never said microwaving dried goods “burns it”.

Oh, and to repeat…

Not an assumption, an observation.
It’s your claim that the rice doesn’t absorb the waves, which you conveniently left out.

I’ll leave you to it.

This confirms that raw rice has a moisture content which is reduced by microwaving.

Not sure anyone has a home microwave oven which can give out 5KW for 90seconds.

The effect of this high-powered industrial microwave on insects in the rice was not published at the time of the study.

A childhood friend informed me of his experiments on the effects of microwaves on insects and the results were deadly - often explosively so…

They do mention bug mortality (100% and 98%). However, how mortality can be 98% for ten bugs is a bit of a mystery.

And whether similar results can expected with the much smaller moth larvae and eggs is at least an open question.
