The term the nuclear holocaust sound like this is a well defined event, maybe with number of atomic weapons involved, where they get triggered, what the consequences are for climate (if any) and so on - or is it only about radioactive radiation? This myth probably originated with “The Cockroach Papers: A Compendium of History and Lore”. Since radiation gradually destroys organisms on the cellular level, the MythBusters monitored the radiated roaches for 30 days. After a month, half the roaches exposed to 1,000 rads were still kicking, and a remarkable 10 percent of the 10,000 rad group was alive. The results confirmed that cockroaches can survive a nuclear explosion — but only to a point, as none of the critters in the 100,000 rad group made it through. To evaluate the longer term affects of the test on the insects, the MythBusters took them home along with a control group that hadn't been exposed.
The bugs in the 1000 rads and 10,000 rads tests appeared fine but 90% of the cockroaches in the 100,000 rads group immediately died. Based on these results, the cockroaches clearly weren't the best survivors of a nuclear blast.
However, the flour beetles did much better and the fruit flies might have done better if their normal lifespan wasn't 30 days.
Cockroaches have been around for at least 300 million years, and there are 5000 species worldwide.
Pest cockroaches can withstand temperatures as cold as 32°F (0°C), but will die if the temperature goes much below that. Due to the large variety of species it's hard to make a general statement about how well "a cockroach" would fare in the aftermath of a nuclear war. But it seems they have a better chance at surviving the radiation and they are less picky eaters than we humans. While Oliver_C's (excellent) answer look at the effects of radiation on cockroaches as an indication of whether or not they would survive a nuclear explosion, the question is about surviving a nuclear holocaust which means factors other than radiation are also an important determinant. The National Geographic documentary Aftermath: Population Zero states that no, cockroaches would not survive without humans. Given that it is unlikely there would be central heating up and running if a nuclear holocaust were to occur, it is unlikely that cockroaches would survive outside of the tropics and even that is questionable if a nuclear winter is in place. A nuclear winter could vary in intensity depending on how much remaining material was in the atmosphere.
As such I don't think it's fair to say cockroaches would not survive a nuclear holocaust, although they would survive a nuclear explosion. 1 - Not a great reference, although it supports what I found for the various different species, with the longest seeming to be 4 years.

The recent post about earthquakes and nuclear explosions caused me to wonder about something that most of us have probably heard several times before, that cockroaches have a better chance of surviving a nuclear explosion than we humans do. This entry was posted in animals, cockroaches, dangerous, death, environment, radio activity, Science, Uncategorized, urban legends. Radiologists have found that humans can safely withstand a one-time exposure of 5 rems and a lethal dose is 800 rems or a little more. Studies show that American cockroaches can withstand 67,500 rems and German cockroaches between 90,000 and 105,000 rems.


There’s also a brown-banded cockroach and an Oriental cockroach and probably many other types too.
So “Yes”, cockroaches could withstand the amount of radiation generated by a thermonuclear explosion. And apparently the first thing that a cockroach does after being touched by a human is to clean itself, and what’s more, some cockroach species can go for a month without food, and survive for a month on a drop of water from a dishrag. There are actually about 4,000 species of cockroach, of which 30 species are associated with human habitations, but you’re right (as usual ?? ) that only four species are considered pests. Cockroaches have survived in even the most hostile environments because they possess several unique physical features, an amazing reproductive process, and an immune system that has frustrated even the best efforts of exterminators to get rid of them. The spines on the legs were earlier considered to be sensory, but observations of their locomotion on sand and wire meshes have demonstrated they help in locomotion on difficult terrain. Cockroaches leave chemical trails in their feces, as well as emitting airborne pheromones for swarming and mating. Daily rhythms may also be regulated by a complex set of hormonal controls of which only a small subset have been understood. Research has shown group-based decision-making is responsible for complex behaviors such as resource allocation. Another study tested the hypothesis that cockroaches use just two pieces of information to decide where to go under those conditions: how dark it is and how many other cockroaches there are.

If you want to kill an American cockroach with radiation, it will take 67,500 rems to do the job.
Note, that the amount of nuclear weapons is changing over the decades, so what might have been true 1960 might have been wrong 1980 and true again today - or not. In that book, the journalist Richard Schweid notes that roaches were reported to have survived the blasts at Hiroshima and Nagasaki.
They are quite hardy, able to survive radiation doses at 10,000 rads, which is 10x the lethal dose for humans. It is worth noting that fast-breeding species such as cockroaches ought to adapt to survive high levels of radiation than slow-breeding species. More so, there is heat, pressure, lack of food, maybe atomic winter taken into consideration. The documentary states that cockroaches are imports from the tropics and only flourished due to central heating provided by humans. Given that the question uses the term nuclear holocaust, I will assume the a worst case scenario.
What I can't find is the lower limit temperature for cockroaches being able to survive.
Their body shape allows them to squeeze into small cracks or holes in walls and ceilings or dart into drains, thus avoiding all dangers. Pest species adapt readily to a variety of environments, but prefer warm conditions found within buildings. These chemical trails transmit bacteria onto surfaces. Other cockroaches will follow these trails to discover sources of food and water, and also discover where other cockroaches are hiding. In 2005, the role of one of these proteins, pigment dispersing factor (PDF), was isolated and found to be a key mediator in thecircadian rhythms of the cockroach. In a study where 50 cockroaches were placed in a dish with three shelters with a capacity for 40 insects in each, the insects arranged themselves in two shelters with 25 insects in each, leaving the third shelter empty.


The study created a set of tiny robots that appear to the roaches as other roaches and can thus alter the roaches’ perception of critical mass. On January 21st, 1968 the New York Times ran an article that read, in part, "A nuclear war, if it comes, will not be won by the Americans … the Russians … the Chinese. So while cockroaches may be wimps now, it is possible that they may adapt faster than some other species and – and the end of the day beat out other species. Surviving at 0 degrees is not that impressive, not when Sagan estimated temperatures to drop by 36 degrees Celsius (although that paper has been disputed).
Many tropical species prefer even warmer environments and do not fare well in the average household. Thus, cockroaches can exhibit emergent behavior, in which group orswarm behavior emerges from a simple set of individual interactions. When the capacity of the shelters was increased to more than 50 insects per shelter, all of the cockroaches arranged themselves in one shelter.
They can also passively transport microbes on their body surfaces including those that are potentially dangerous to humans, particularly in environments such as hospitals. For one thing, they're really good at hiding themselves deep within tiny cracks and fissures. It does seem like cockroaches might stand a chance, should we make the unfortunate choice to detonate a nuclear bomb on this planet. Researchers found a balance between cooperation and competition exists in the group decision-making behavior found in cockroaches.
But hiding under rocks or burrowing in the soil won't be enough to protect them from the impact of a nuclear bomb. In fact, the amount of radiation they can tolerate is within the range of a thermonuclear explosion. Approximately three weeks after mating the females lay their eggs, which hatch some forty-five days later. The models used in this research can also explain the group dynamics of other insects and animals. These cerci are covered with tiny hairs that, like antennae, are sensitive to things as small as speck of dust or as seemingly innocent as puff of air.
If they can not find food, they can sustain themselves for up to a month wiithout food, as long as they have water. Even 50 meters away from the epicenter of the blast, temperatures would reach about 10,000 degrees instantly.

May 6, 2012 HeldervaxAny chance you have a link to a bit more info on the experiment that sent the tardigrades into space, I’m curious about the ones that hatched from the eggs of the ones that were sent into space. If we could condition them to survive in the vacuum of space unprotected we could learn a lot about how to protect ourselves from radiation, hell, maybe even a way to utilize it or clean it up.
