Short Answer 
To identify pest presence, look for key signs such as balled-up paper scraps for nesting, droppings, and damaged goods. Differentiate pest issues from maintenance problems, as signs like pinholes or unusual smells indicate operational concerns rather than pests.
Step 1: Recognize Key Signs of Pests
When assessing for pest presence, it’s essential to identify clear indicators. One of the most telling signs is the presence of balled-up paper scraps found in drawers or hidden areas. This behavior suggests that pests like rodents or insects may be using these scraps to create nests.
Step 2: Look for Additional Evidence
In addition to paper scraps, there are several other signs that can indicate pest activity. Keep an eye out for the following signs:
- Visual sightings of pests themselves.
- Presence of droppings or frass (which is insect waste).
- Damaged goods or food items.
Step 3: Differentiate Between Issues
It’s important to differentiate between pest-related issues and other operational problems. Signs such as small pinholes in plumbing, oily substances, or unusual electrical smells indicate maintenance concerns and do not suggest pest presence. Understanding these differences is crucial for maintaining a safe and hygienic environment in operations.
