A 75 year-old woman from Germany could not sleep at night because a colony of ants kept ringing on her door bell
The 75-year-old woman from Offenburg in Germany could not figure out who was the prankster who kept her up all night. Eventually the woman called the police and after an investigation that was carried out, they found out that a nest of ants was causing the problem.
Apparently the nest was so big that it kept pressing the switching elements causing the door bell to ring constantly. The nest was eventually removed with a knife and now the old woman can sleep again.
