Travel content creator Dianah Daisy recently paused her usual updates on scenic destinations to share a curious observation with her followers. In a post shared via TikTok, she raised a question that has puzzled many homeowners. She asked why cockroaches almost always seem to die facing upwards.
Daisy is well-known for her travel-related content, but this time her focus shifted to a common household phenomenon. She noted that the position of a dead cockroach is so consistent that it has even inspired specific cultural terminology.
A Sudden Realisation
The creator admitted that she had not previously paid much attention to the posture of these insects. However, a recent encounter sparked a moment of reflection.
“Why do cockroaches die wakiwa wameangalia juu cos I just found one and it’s just facing upwards, and I have never been keen to observe,” she stated in her video.

“Today it just hit my mind and I was like, mmh, hapo ndio phrase ‘kifo cha mende’ ilitokea. Who is this person that observed this and came with the kifo cha mende?”
The Origin of ‘Kifo cha Mende’
In Kenya culture, the phrase ‘kifo cha mende’ is a common expression. It translates literally to "the death of a cockroach." It is often used to describe someone lying flat on their back with their limbs in the air.
Daisy speculated that the person who coined this phrase must have been a keen observer of nature. She remarked that the term is remarkably accurate given how frequently the insects are found in that specific position.

The Science of the Flip
While Daisy’s observation was based on curiosity, there is scientific reasoning behind why cockroaches end up on their backs. Entomology experts note that cockroaches have a high centre of gravity. Their bulky bodies are supported by long, thin legs.
When a cockroach is weakened by old age or exposed to pesticides, it loses its muscle coordination.This often leads to the insect flipping over. On smooth surfaces like modern tiles or hardwood floors, a cockroach lacks the leverage to right itself.
