Insect control devices must and be able to retain the electrocuted insects inside the device

Answer:
Be rated for safety by the USDA
Explanation:
Presence of insect pest around areas of food production poses a lot of risk such as contamination of food which might impact negatively on public health. However, in an attempt to control these insect pests, the problem of food contamination as a result of insect infestation that we're trying to solve might still be increased if safety measures are not strictly adhered to when manufacturing and using insect control devices.
Hence, it is necessary and of utmost importance that insect control devices must be rated for safety by USDA to ensure compliance with laid down measures and protocols for safe control of insect without contamination of food.
