One thing I have heard over and over is to change the batteries on the smoke detectors when you change the clocks for Daylight Savings Time!
You would think I would learn.
At least I wasn't completely fooled this time like I was a couple of years ago.
I still laugh about my silly mistake: terry6ny.blogspot.com/2012/05/crickets-and-stuff.html.
Being previously informed I went right after the smoke detectors and sure enough it was the upstairs one that was serenading me every now and then.
Talk about learning the hard way. At least I saved a lot on bug spray this time.
