The cockroach (ゴキブリ, Gokiburi?) is an uncommon bug that can be found throughout the year in the GameCube games and Wild World, either inside the home or outdoors where it can be caught with a net. In subsequent games cockroaches cannot be caught, but can still be found inside neglected homes after a week of not playing. They are often seen as the secondary antagonist of the Nintendo franchise, Animal Crossing.

In the outdoors they can be found resting on trees, flowers (GCN only), turnips and candy, but are only common on the latter two objects. They are generally regarded as being disgusting, most notably by Blathers, the curator of the museum and a sufferer of Entomophobia. They have the lowest selling price of any bug, at 5 Bells.
