Which of the following is a sign of pest infestation?

All of the listed options are indeed signs of pest infestation, making it essential to recognize each of them to effectively identify potential problems in a facility. Torn packages indicate that pests may have accessed stored food or goods, demonstrating their presence. Droppings that resemble pepper are often indicative of rodent activity, as rodent droppings are small and dark, resembling pepperflakes, making them a key sign of an infestation. Black, greasy marks on baseboards typically result from rodents or other pests moving along that surface, as their bodies leave behind oils and dirt, which can create visible trails. Recognizing these signs can help in early detection and prevention of more significant pest issues in a facility.
