If you haven't lived in the countryside, you probably don't know why adobe houses collapse when no one lives. Adobe houses are actually houses made of earth, and the tops of the houses are all made of wood. On the wood, everyone will lay tiles. If the house is inhabited, it will be renovated in time to prevent water from entering the wood and corroding the wood. Anyway, no one lives in the house, even if it leaks, no one knows. If water is soaked in wood for a long time, it will make the wood rot, and then the roof will collapse if it can't support the weight.
In fact, as we all know, there will be cockroaches or some centipedes and other insects in the general house. If someone lives in the house, it will definitely light up at night, and there will be some light. Like cockroaches and centipedes, they are afraid of light and don't like it, so they are generally in a dark and humid environment. If the house is unoccupied, these bugs will visit because of rain leakage or dark, and if they move around in the soil, it will lead to.
