    Spiders?

    Or more likely could it be when the occupants die, instead of someone new moving in they torch the place and start over?

    Edit: nevermind, they suggested that further down in the article.

      Yeah, spiders seemed like the obvious answer to me. I would have also accepted centipedes.

    Interestingly, Japan does this now. They tear down and rebuild wooden houses about every 20 years and concrete every 30. But the cause for Japan is earthquakes which I don’t think would apply much here.

    […T]hey have discovered evidence of numerous ancient civilizations on the planet, all destroyed by fire, with the collapses occurring about 2,000 years apart. […E]arlier civilizations on Lagash were destroyed by people who went insane during previous [solar] eclipses and, desperate for any light source, started large fires that destroyed cities.
