Whether you’ve had a lot of dealings with cockroaches, or just a fleeting experience of one or two, we can all agree that they are disgusting, large, and almost impossible to kill. Many home owners who have tried getting rid of cockroaches on their own understand the struggle on a personal level. But, despite the horror of them, cockroaches make for a lot of interesting facts!
They can evolve as a species in just a few generations
In some cases cockroaches can physically change the way their bodies work (like becoming immune to a pesticide) and then pass that gene on to their children, so that just a generation or two is all it takes for them to evolve into a species fit for survival.
They can live without their heads
Better than a chicken, a cockroach could – hypothetically – live its whole life without its head. Their head isn’t the main organ of their body, so survival would be possible.
They can hold their breath for 5 minutes
One of the main reasons that a lot of pest control for cockroaches fails, is because they simply hold their breath until they get out of the line of fire from pesticides. The nerve of these creatures!  
Their DNA has changed very little since the beginning of time
Since they came into being, their core DNA has changed very little, meaning that they were doing something right from the very beginning!
Even radiation can’t kill them
Yes, it’s true. Cockroaches could survive a nuclear apocalypse if it ever did come. They can survive high levels of radiation and then simply mutate their DNA as mentioned above and be A-OK in a world that would kill every other species.
Females can reproduce without males
You read that right. Females don’t need male interaction in order to have babies. This is both useful, but frustrating if you thought simply killing all the male cockroaches would do the trick.
After reading all of these fun facts, you have to admit that cockroaches are some pretty fascinating (yet gross) insects!  So, just think about all of these fascinating facts next time you see one disappear around the bottom of your kitchen cupboards. They’re morbidly intriguing pests.
