the first thing to consider in killing cockroaches in restaurants is safety. Because restaurants, especially kitchens, are in direct contact with food, if the cockroach medicine used is toxic and accidentally touches the food, the consequences will be even more unimaginable. All toxic cockroach drugs can't be used in restaurants, especially sprays, which are the easiest to spray on food. It is certain that the only cockroach-killing drugs are gel bait, such as Jiebing gel bait and Lehan gel bait. Its active ingredients are non-toxic, tasteless and harmless, and people will be fine if they eat them. Moreover, their colloidal drugs can be directly squeezed into the corner of the kitchen, and the drugs contain attractants to induce cockroaches to take the initiative to eat. After the cockroach is poisoned, it will die. It is not only non-toxic, but also can kill cockroaches for a long time, so it is the first choice for restaurants to kill cockroaches.
