Electrical Wiring in the Home/Loud Chirping


Help!  I have an extremely loud and piercing chirping coming from inside my wall or ceiling, which started early this morning.  It sounds like a smoke detector when the battery dies, but there are none in this area, nor is there a CO2 detector in this area.

I've tried turning off the main power breaker at the breaker box, but that didn't stop it.  

The chirping occurs somewhat randomly.  It might chirp twice in a minute, then not again for 2 or 3 minutes.

I have an old ADT security system, but it's been disabled for years and has been disconnected from it's battery at the main ADT box in the basement.

The house is about 20 years old, and I've been in it for 15 of those years, so I would have guessed that if there were a smoke detector buried in the wall somewhere, I'd have come across this way before now.

Any suggestions?  

Thanks in advance!

I am not sure either.

I would think that a smoke detector would have chirped with a low battery a long time before 15 years.  Could it be some kind of insect?  It's the year of the 17 year locust.  Is there an attic above that you can get into and perhaps get closer?

Sorry I couldn't be more of a help.
