Open ditches in the operation room of catering industry shall be covered with nets or other articles, and shall not be exposed.
Rat-proof door: you can nail an iron plate 30-50 cm high in the lower half of the door to prevent rats from biting the door panel, or add an iron gate 60 cm high to keep rats out. It is best to prevent rats in the whole house.
Narrow the gap: repair the gap between the door and the ground, the door and the door, the window and the windowsill, so that the gap is not more than 0.6 cm, to prevent house mice from entering.
Hardened ground: repair the damaged and unhardened ground in time, or harden the road surface to prevent rats from stealing holes and nesting.
