Why Do Cockroaches Die on Their Backs?

Cockroaches can die in several ways. Some will try to right themselves but eventually give up, while others will simply play dead. In the end, they will fall to the ground and be eaten by another insect. However, a few cockroaches will die on their backs if they are not touched.

In their natural habitat, roaches die on their backs because they are easy prey for predators. This makes them much safer inside the home than outdoors. The largest roach in the world lives only in South America, where it grows to be six inches long with a one-foot wingspan.

Insects’ bodies are built with an exoskeleton to protect and support them. As such, when they die, they can’t maintain muscle tension on their legs and will naturally fall into a relaxed state. Consequently, when a dead bug lies on its back, its legs curl up.

Cockroaches often die on their backs because they are too old to flip themselves upright. This behavior is a form of “playing dead” and scientists refer to it as “thanatosis.” Cockroaches can even hold their breath for several minutes before they die.

Cockroaches can also die on their backs for a variety of reasons. For example, if a pesticide washed their bodies, they may become weakened and be unable to flip back over. They may also die of starvation or dehydration.
