Why Do Roaches Die on Their Back? | Complete Explanation

Have you ever noticed that when roaches die, they usually fall on their back?

Isn’t this weird?

For example, after coming in contact with your roach killers, you would’ve often seen that roaches turn upside down, on their back, while taking their last breath.

Now, does this happen all the time when they die, or is it related to a particular situation?

We were very intrigued by all these questions as well, so we decided to do some digging and find out some answers.

Let’s get started.

Why Do Cockroaches Die Upside Down?

After the death of this insect, there’s less chance of bacteria, but you will be wondering why they die upside down.

Dying or dead insects have a similar pose, i.e. lying on the back, legs sticking up in the air.

This is actually a symptom of the bug’s decreased coordination and its failing nervous system.


Normally, if a bug is knocked out on his back, it can use its legs to rock on the sides till it rights itself.

However, if the bug won’t roll back onto its abdomen, it’s because it has become weak or because its nervous system isn’t functioning properly; it will remain stuck on its back.

Because the bug won’t get any nutrients and protect himself from the predators or the elements when it’s not in this position, it soon dies if he can’t flip over.

When a cockroach dies of old age, its high center of gravity gives it a pull back on the floor, and the weakened muscles and rounded back prevent it from righting itself, particularly on smooth surfaces.

Do All Roaches Die on their Back?

As there are different species of roaches worldwide, it’s difficult to capture all of them.
