Ahhaah. Psocids!!! Thank you.

From your wiki link it mentions that psocids also make this sound.

I had seen the psocids, and did at one point think that it could be them, but dismissed the idea since they seem too frail to make such a loud noise. They squash with a light touch of the finger. Maybe we have a few specimens of a more heavy duty variety that makes this noise - otherwise our house would sound like a clock factory.

A quick web search.
