Residents of an apartment building in Germany were surprised by a series of late-night doorbell rings, which turned out to be caused by an unexpected culprit. Initially, they suspected it was a common prank known as ‘klingelstreich,’ where individuals ring doorbells and flee, similar to the game ‘knock knock ginger’ in the UK.
However, the mystery was solved when authorities found a slug moving up and down the doorbell plate, setting off the sensors and causing the continuous ringing. One resident, Lisa, shared her experience with a local publication, mentioning that she initially ignored the late-night ring, attributing it to neighboring children. But the situation escalated as multiple bells in the building kept chiming.
After identifying the slug as the mischievous bell-ringer, the police relocated it to a nearby grassy area to respect its territory boundaries. Lisa also noticed the slimy trail left by the slug on the sensors during a closer inspection.
Instances of animals interacting with doorbells have been cautioned against before. Sometimes, it is the doorbell triggering a pet’s reaction, such as dogs barking in response to the sound. Animal charity Blue Cross has advised pet owners on desensitizing their dogs to doorbell sounds through gradual exposure and positive reinforcement to curb excessive barking.
