Your microwave will heat the food to be steamy hot but Cockroaches will still be roaming inside without being bothered. Why cockroaches don’t die in microwave?
There are several reasons; first, microwaves heat your food by means of radiation and second, Roaches are highly resistant to radiation as big as nuclear blasts.
Cockroaches are also heat resistant and will easily lose any heat to their surroundings to cool off.
Therefore, Roaches won’t die in the microwave primarily due to their anatomy and due to the way a microwave works.
Why cockroaches don’t die in microwave
Roaches are Hardy Insects – Resistance to Radiation
Cockroaches are one of the most resilient insects. Some species can go a month without eating and thrive on scarce resources like the glue on the back of postage stamps. Others can go 45 minutes without breathing. In laboratory trials, nymphs of the Japanese cockroach (Periplaneta japonica), which hibernate in frigid winters, have survived twelve hours at -5 to -8 °C (23 to 18 °F).
Although many insects other than cockroaches can survive decapitation, and popular claims of the longevity of headless cockroaches do not appear to be based on published research, experiments on decapitated specimens of several species of cockroach found a variety of behavioral functionality remained, including shock avoidance and escape behavior. When refrigerated and fed nourishment, the severed head can survive and wave its antennae for several hours, if not longer.
According to popular belief, cockroaches will “inherit the earth” if humanity is destroyed in a nuclear war. While cockroaches have a far higher radiation resistance than vertebrates, with a lethal dosage that is roughly six to fifteen times that of humans, they are not particularly radiation-resistant when compared to other insects like the fruit fly.
The capacity of the cockroach to survive radiation can be explained using the cell cycle. When cells divide, they are particularly exposed to the effects of radiation. When a cockroach molts, its cells only divide once. Because not all cockroaches molt at the same time, many would be unaffected by an acute burst of radiation, yet the persistent radioactive fallout would be dangerous.
Roaches aren’t entirely resistant to radiation, but they can take a lot.
If a cockroach is inside the microwave as you warm your food, its body will be exposed to high power microwave radiations if it is sitting idle in the Antinode position.
Because it has a small amount of water in its body, it will absorb less radiation and thus gain less heat than food with a lot of water, fat, or sugar.
& whatever heat the roach’s body absorbs from radiation is transferred to the surrounding air, which aids in cooling (large body area = better cooling).
A sensitive roach will also not stay in one spot; it will move from Antinode point (high power area) to Node point (low power area) where it will be less affected.
You might find this roach in a confused state by the time you turn off your oven and take out your hot food (15–20 minutes). It has no idea what is making its blood warm.
So, if you’re expecting a fried crispy cockroach inside the oven, try turning it on for a longer period of time next time. I don’t think 1–2 hours would suffice.

Basics of how a microwave works
Magnetrons, which are usually found on the right side of an oven, emit high-power microwave radiations.
When these waves hit food containing molecules of water, fat, sugar, and other substances, their molecules rotate at a high rate, causing friction and heating.
There will be a few spots inside the oven where the net energy due to waves is zero (see next section), so the food under these spots will not receive any energy or heat (uneven cooking). This problem is solved by using a rotating table inside the oven, which moves the food and exposes it to radiation from all sides for uniform cooking.
For a better understanding, we’ll pick one of the emitted waves.
Consider a wave emitted from the right side of the magnetron, which will strike the oven’s left (metallic) wall and reflect back to the source.
Standing wave is formed by the main and reflected waves, which are two waves of equal frequency and amplitude moving in opposite directions.
There will be two types of points on the wave as a result of the two wave combination (standing wave):
The Anti-node peak points have a lot of energy.
Nodes are points where waves cross and cancel each other’s energy, and they have no power.
How can cockroaches survive a nuclear bomb but not raid?
Insecticides are potent drugs that are specifically designed to affect their neurological system when used directly, and many of them have long-term side effects. Nuclear bombs that are not specifically targeted at cockroaches may miss them underground for long enough for the radiation to dissipate sufficiently for their survival.
The widespread belief that cockroaches would survive a nuclear explosion is obviously exaggerated.
Of course, any exposed cockroach would not survive a missile strike, let alone the massive shock wave that would follow, let alone the extremely high radiation levels. True, insects are more radiation resistant than vertebrates due to their smaller size and filtering exoskeleton, and some pest cockroaches are well-known for their ability to survive on very little food and reproduce at an astonishingly fast rate for their size.
Many researchers believe that in the event of a major nuclear accident or attack, cockroaches would likely survive longer than vertebrates. Time will tell whether this is true or not.
Insecticides are now chemicals that are carefully chosen to affect the nervous system of insects, causing death as quickly as possible while remaining on surfaces for a long time (residual effect). They’re made to get rid of cockroaches. Nuclear attacks, on the other hand, are designed to destroy cities. That’s all there is to it: the right weapon for the right foe.

Cockroach Adaptability – Roaches can Hide Anywhere
One of the most common household pests is cockroaches. Most of us have probably run into this speed demon several times. Cockroaches are difficult to kill, making cockroach pest control nearly impossible. If you see one, it’s likely that there are several more who have taken refuge in your home. However, there are a few places in your home where you can frequently find these obnoxious creatures.
Here are a few of them:
1. Ceilings
Cockroaches can scuttle, fly, walk upside down, and flatten their bodies before vanishing into small crevices and holes. They also enjoy hanging out in dark rooms’ ceilings, which is odd given that they prefer dark corners to wide open spaces.
When the lights are turned on, however, most of them flee to a less visible location.
Cockroaches are difficult to kill or knock off without them falling on you, so catching ceiling creepy crawlies can be difficult. They also have a habit of landing safely on the floor and then disappearing into an unreachable hiding place.
If your ceiling has cockroaches, it is very likely that it has cracks or holes through which the cockroaches can move back and forth. For cockroaches, ceiling these gaps is an excellent pest control measure.
2. Pipes
Cockroaches are one of those obnoxious creatures who enjoy getting wet and being near water. Pipes enter a house through walls, floors, and the backs of cabinets, and these areas are frequently damp and moist, as well as constantly releasing bits of warm condensation for roaches to get into. Exposed pipes on the walls, as well as the areas around washers and dryers, are popular hiding places.
Insulating and taping gaps between piping and walls, as well as having false cupboard and cabinet backing, can help keep these areas dry and less inviting, thereby preventing cockroach infestations. Some areas, such as a bathtub, where pipes end with a health faucet, may be more difficult to control.
Cockroaches can easily climb up these open faucets and even fall into your bathtubs and sinks when you aren’t looking.
3. Home furnishings
Cockroaches, like us, enjoy our plush, comfortable furniture with just the right amount of firmness, softness, and warmth. The gaps between the cushions are ideal places for these pesky creatures to snuggle in, allowing them to feel the soft fabric on their top and bottom sides. Cockroaches eat a wide variety of foods. While they prefer sweet and starchy foods, some varieties enjoy eating paper and make it their preferred place to dispose of their waste. Roaches are attracted to the smell and texture of paper, as well as glue. Cardboard boxes used to stack food and beverages are ideal places to hide, eat, and leave a trail of feces or bacteria that have adhered to their bodies.
Cockroaches not only eat cardboard and paper, but they also destroy it with oils and acids, which break down the fibers and leave a foul odor behind.
Leaving stacks of newspaper or cardboard out in the open invites these unwelcome pests in. These roaches would not be able to feed on them if they were kept in tightly sealed containers or cupboards.
These roaches also benefit from the darkness and ample hiding space provided by bookshelves. The paper and book bindings will be eaten by cockroaches. Taking your books out and inspecting them for roach eggshells and torn pages on a regular basis is a good idea.
Cockroaches can be controlled by applying HIT anti-roach gel to these areas.
They are so fond of our furniture that they may lay their eggs on it. In a matter of weeks, these hardened colonies of eggs will hatch, producing tens to thousands of younger ones.
Under tables and chairs made of wood and plastic, you may also find yellow and whitish egg casings.

5. Appliances
Cockroaches spend a significant amount of time inside and outside of our appliances. Stoves and refrigerators have a variety of nooks and crannies, and the warmth from a running motor can provide shelter during the day and foraging at night.
Water heaters are the most comfortable abode because they provide both water and warmth, and they are typically found in quiet and secluded locations.
Cockroaches are also found in small appliances on kitchen counters. Microwaves, ovens, blenders, and coffee makers may be among their favorite hiding places. Even toasters can be a hiding place, and shaking off the crumbs may not be enough if you’ve discovered one of these speed demons at home. Cleaning all appliances, including the refrigerator, at regular intervals is an important pest control measure to follow.

6. Kitchen
Kitchen sinks and dishwashers, as well as any areas with traces of food particles or crumbs, are some of the hotspots for these creepy crawlies.
Most of the time, these roaches wait until the lights are turned off before running amok in the house. Some varieties, however, will come across your path even during the day. Those hiding in drawers are a source of concern because they leave bacteria on silverware and kitchen utensils. Using a DIY pest control product like the HIT anti-roach gel to treat these areas is a great way to get rid of cockroaches quickly.
7. Restrooms
Bathrooms, like kitchens, are a great source of moisture that cockroaches enjoy. Although bathrooms do not contain food particles like a kitchen, they do contain other items that roaches enjoy, such as soap residue, discarded paper tissues, hair strands, and soiled toilet paper.
They can usually find enough to eat and drink in a bathroom and do not feel the need to venture out.
Most cockroaches confine themselves to the bathroom and kitchen because these two rooms provide enough food for them to survive.
However, there are some types that can be found almost anywhere, such as any surface with traces of humidity or surfaces that contain water.
Application of the HIT anti-roach gel in strategic locations in bathrooms can also help kill cockroaches effectively.

8. Cabinets, closets, and cupboards
Roaches need no excuse to travel throughout the kitchen, sometimes as an uninvited visitor in an empty bowl in the vessels cabinet or as an extra addition in the cereal box.
They can also be found in closets, and they lay their eggs in linen cupboards.
Cockroaches prefer the inside corners of cabinets, drawers, and cupboards. They’re upside down and can be found there.
Food must be stored in airtight containers to keep these creatures away, not only because they are disgusting, but also because they may carry germs or other bacteria.
Cockroaches hiding in the hinges and edges of cupboards and cabinets can be killed by applying anti-roach gel along the hinges and edges.
9. Electronics and décor
Why cockroaches don’t die in microwave?
Cockroaches can jump out from behind books on shelves, under or inside electronics and light fixtures, and even your most prized souvenirs and candles.
They blend in so well with the decor that you might not even notice them.
Cockroaches can be found behind picture frames and mirrors, both mounted and freestanding.
Other favorite hiding places include computers, televisions, stereos, clocks, and other electronics.
