Catering fly-killing lamp is a kind of equipment designed to prevent food from being polluted by insects such as flies. These lamps have ultraviolet light sources, which can attract and kill insects that fly into the range. However, if the catering fly-killing lamp is not plugged in and powered on, it will not be able to play its expected function. Therefore, in this case, there will be no punishment for the unplugged catering fly-killing lamp.

The catering industry has certain regulations and standards on hygiene. In order to ensure food safety and hygiene, catering operators should take other effective measures to prevent pests, such as keeping clean and hygienic, regularly cleaning up garbage, and storing food in a sealed manner to avoid food pollution. If the restaurant is found to have sanitary problems, the relevant regulatory authorities will take corresponding punishment measures, but there is no direct legal provision on whether the catering fly-killing lights are unplugged.
