(1) Effective measures intended to minimize the presence of rodents, flies, cockroaches, and other insects on the premises must be utilized. The premises must be kept in such condition as to prevent the harborage or feeding of insects or rodents.

(2) Devices that are used to electrocute flying insects must be designed to have escape-resistant trays. Devices that are used to electrocute flying insects and that may impel insects or insect fragments or to trap insects by adherence must be installed so that:

(a) the devices are not located within 5 feet of a food preparation area; and

(b) dead insects and insect fragments are prevented from being impelled onto or falling on exposed food, clean equipment, utensils, and lines, and unwrapped single-service and single-use articles.

(3) Dead or trapped birds, insects, rodents and other pests must be removed from control devices and the premises at a frequency that prevents their accumulation, decomposition, or the attraction of pests.

(4) Rodent bait must be contained in covered, tamper-resistant bait stations.

(5) Tracking powder pesticide may not be used in a food service establishment. A nontoxic tracking powder such as talcum or flour may be used, but may not contaminate food, equipment, utensils, linens, and single-service articles.

(6) Openings to the outside must be effectively protected against the entrance of rodents. Outside openings must be protected against the entrance of insects by tight-fitting, self-closing doors, closed windows, screening, controlled air currents, or other means. Screen doors must be self-closing, and screens for windows, doors, skylights, transoms, intake and exhaust air ducts, and other openings to the outside must be tight-fitting and free of breaks. Screening material must not be less than 16 mesh to the inch.
