tapping sounds in cinder block wall

I live in Florida in a 1 story, cinder block wall home. The house is about 20 years old and i've lived in it 6 years. Over the past 4 weeks i've heard a tapping sound coming from what sound like the inside of the wall. It almost sounds like someone is bouncing a hard rubber ball outside the house. It's only one tap at a time, but they happen only at night. Sometimes they wake me up. Last night between 2-5am I heard about 4 taps. I've had 2 pest control companies check in the attic and there's no evidence of pests. There is no plumbing in the wall and no one is using the water at this time of day.

What else could it be?

Thanks!
