A nest of ants was found terrorizing a 75-year-old woman in the German town of Offenburg, repeatedly ringing her doorbell throughout the evening. The woman called police at 3 a.m. to report the mysterious ringing.
Officers soon discovered a colony of ants had made their home in the switch, pressing elements together to ring the bell. They silenced the colony by removing them from the door with a knife.
The officers couldn’t identify the species of ant responsible for the scare, but The Guardian speculates that the pharaoh ant may be to blame. This warmth-loving insect is attracted to electric currents and can only survive in cold northern Europe with the help of humans.
