That looks like a lizard tail, most likely from a small gecko hiding in your ceiling or wall.
A few clues:
- The texture and slight segmentation match a gecko/lizard tail.
- The tapering, flexible shape is typical of lizards—not insects or worms.
- Geckos often live inside walls/ceilings, especially in warm areas.
👉 What’s probably happening:
The lizard is inside the ceiling, and its tail is sticking out through a gap or crack.
👉 Important to know:
- Geckos are harmless and actually help by eating insects.
- If the tail gets stuck or the lizard feels threatened, it can even drop its tail and escape.
👉 What you can do:
- Don’t pull it (you could injure the animal or make a mess).
- Check for small openings and seal them later.
- If it bothers you, a pest control service can safely remove it.
