Why Cockroaches Are Hard To Kill

Anyone who has suffered through a cockroach infestation knows these insects seem almost impossible to kill. This is probably one of the reasons there are so many cockroaches in London. But why is this? There are many reasons. For example, some of the reasons why cockroaches are hard to kill include the following.

Evolution makes cockroaches resilient

Why cockroaches are hard to kill is basically because of evolution. These bugs have evolved over millions of years to the point where they are nature’s ultimate survivors. Cockroaches are able to survive in almost any environment. They can live in the hottest deserts, humid tropical regions, and even sub-zero conditions.

No matter what the elements are like, cockroaches thrive with very little effort. In fact, cockroaches are even able to live through the radiation caused by nuclear blasts.

Sustenance Needs

Another reason why cockroaches are hard to kill is because they eat almost anything. This includes any type of food, even rotten food. They also eat manmade materials such as cardboard, paper, and fabrics. Not only that, cockroaches are cannibals and will eat other cockroaches. They are even able to survive for up to a year without food, and two weeks without water. What this essentially means is that they need almost no food to survive, making them very difficult to get rid of.


These creatures also breed phenomenally fast. This is probably the biggest reason why cockroaches are hard to kill. In fact, each female can produce in excess of 30,000 new cockroaches. They are ready to breed only a few weeks after birth and can lay up to 8 egg capsules. Every one of these capsules contains about 50 eggs, meaning cockroaches can reproduce at an exponential rate.

Not only do they breed quickly, but getting rid of their offspring is extremely difficult. Their eggs and larvae are very, very tiny. What this means, is that most of the time these are overlooked. No matter how hard you clean or how much poison you use, there are often eggs and larvae left behind. If even one or two of these remain, then the cockroach colony will regenerate.
