What are the possible causes of this noise in my wall?
posted by skinnydipp to home & garden (11 answers total)
It is occurring in one room, in the outside wall of my house. It doesn't sound like mice to me. My girlfriend describes it as a munching sound, whereas when I first heard it I thought of someone gently releasing a handful of small pebbles.
The noise occurs frequently throughout the day for extended periods and seems to occur from the same spot in the wall always. If I bang on the wall where it seems the noise is coming from there is no effect.
I should mention that the chimney to our wood burning fireplace does come up the outside of this same wall and I am located in the Niagara region of Ontario Canada.
Any ideas what it could be and possible steps to address this?
