What Should You Do If It Appears Again?
If you’ve safely documented the object and it returns after being removed, that’s a particularly useful clue.

Photograph it before disturbing it.
Check nearby areas for moisture.
Look for insects or other signs of pests.
Check whether it is emerging from a crack
