If you want to know where if you have any dirty or sticky places in your house, accidentally let a fly in.

If it lands and stays somewhere this means that:

  • There’s something there so it’s going to stay there and nosh. Wherever it’s resting indicates a spot you missed but now the fly found it for you! Isn’t that handy? Now kill the fly and start cleaning.
  • Even if there isn’t anything a fly has landed and thrown up there, so you have to clean it because it’s dirty now.

You’re welcome.
