Let’s dive into deep detail!

Can you kill fruit fly in by microwave heat?

Microwave Fruit Flies

Basically, Fruit flies can survive heating in a microwave. The microwave heating cannot kill them immediately. Basically, the Fruit flies contain water that can easily absorb microwave energy. But if the rate of heat is absorbed proportionally to the volume of the fruit fly. The rate of heat that can escape the inside of the fruit fly basically is proportional to the surface area.

The thermal gradient is basically the temperature difference between the inside and outside of the fruit fly but it is divided by its size. Small creature fruit flies can rapidly reach a steady state where the heat flow is equal to the heat flow out. That clearly means the internal temperature in a fruit fly will increase according to the square of its size. In this way, the heat of the microwave cannot kill fruit flies instantly.

Now the question is how long the fruit fly can survive in the microwave. So roughly you need almost 10 to 12 minutes to get fly dead. It can be cooked just like your food in that the liquids in its body would boil from interaction with the microwaves. But defiantly, it will take time because the Microwave has radio waves about 4 inches long.

So in this way, any object smaller than an inch will receive just a small portion of energy. But it is also a fact that Microwave radiation not only kills insects by its dielectric heat but also affects the reproduction of survivors. So we can say that Microwave radiation, with good penetrability, can easily kill pests existing inside or outside grain kernels. Roughly you need about 12 minutes to kill fruit flies.

so when you microwave the fruit fly then the fluid inside that fly would boil and expand in volume. The carapace of that fruit fly does not allow for this. However, the carapace would rupture as pressure rises.
