Why Do People Call Cockroaches Cockroaches? Unveiling Origins


People call cockroaches “cockroaches” due to the anglicized version of the Spanish word “cucaracha”. This term evolved over time, adapting to the English language.

Cockroaches are among the most resilient and adaptable creatures on the planet, with their lineage tracing back millions of years. Belonging to the order Blattodea, these insects are known for their flattened bodies, rapid movements, and ability to thrive in various environments.

Often unwelcome guests in homes and businesses, cockroaches have gained notoriety for their persistence and the challenge they pose to control and exterminate. The common name ‘cockroach’ is an etymological twist from its Spanish roots, reflecting the insect’s pernicious presence across continents and cultures. As a pest, the cockroach has cemented itself in the human experience, leading its name to be universally recognized and often used in less than flattering contexts. Despite their negative reputation, cockroaches play a significant role in ecological cycles, often acting as decomposers in natural habitats.

Etymological Journey Of The Name



Ever wonder why we call those resilient, nocturnal critters “cockroaches”? Let’s scuttle through history to uncover the roots of this name.

Spanish Roots: From Cucaracha to Cockroach

The name “cockroach” didn’t start in English. This insect was first named in Spain. Spaniards called it cucaracha.

Cockroach Names Based On Appearance

Cockroaches are one of the most recognized and unwelcome house guests. While most of us are familiar with the term cockroach, these pesky insects go by many different names depending on their size, shape, and habitat. These names tell a story about how people perceive these resilient insects based on their distinctive appearances.

Descriptive Terms: ‘waterbug’ And Others

One common name for certain types of cockroaches is ‘Waterbug’. This name comes from the cockroach’s tendency to dwell in damp locations. However, true water bugs are aquatic and unrelated to cockroaches. Other descriptive terms include:

  • Giant cockroach – refers to their sometimes large size.
  • Sewer roach – implies their habitat in unsanitary areas.
  • Brown bug – comes from the brown color of many cockroach species.

The Misnomer: ‘palmetto Bug’ Explained

Particularly in the southern United States, you may hear cockroaches referred to as ‘Palmetto Bugs’. The name suggests they have a connection to the palmetto trees often found in these regions. It is, in fact, a misnomer, as the insects are not true bugs, but cockroaches seeking warm and moist environments which these trees provide. More so, ‘Palmetto Bug’ is a term applied to multiple species of cockroaches and even some beetles. This softens the negative connotation associated with the word cockroach.

  • Pop culture: The term ‘roach’ pops up in movies and TV shows, usually to highlight a dirty or tough character.
