For weeks, I've been hearing a chirping sound at random intervals. At first, I thought it was a bird trapped somewhere in the porch or attic. Then, I heard it in the middle of the night...
Was it a mouse? A mouse was caught in the trap, but it was still happening.
Was it a cat trapped somewhere? Odd sound for a cat.
I started hearing the chirping more often... still, it was only one once. Grr.
Then, I was in the laundry room when the chirp happened again. Super loud! There was a smoke detector in the room, so I took it up to Bob to change the battery. But... it happened again!
Bob looked all over for me and couldn't find any thing (he even looked above the ceiling).
The other day, I had some extra time and decided to clean the shelves off. Most of the items had been left by the previous owner and I just hadn't done much with it yet. I picked up what I thought was a decoration or a toy and it chirped! I about dropped it! lol
Ladybugs. Big, noisy ladybugs.
As it turns out, they are handy water detection devices that would have been useful if they had been on the floor when we had the water in the basement. Now, they were letting us know they need new batteries. Now that I know what they are they have been put in place on the floor.
