What are the indicators of pest activity? (continued)

Insect waste (including frass)

Often you will not see the pests themselves but will see signs of their activity, such as droppings, shed skins and frass. Frass is the finer powdery material that insects pass after digesting organic materials. This may be visible around objects such as storage boxes and packaging materials.

Damage to objects

Unfortunately, the first sign that you have pests may be when they begin to damage your objects and packaging materials. Mice may have chewed up paper items for bedding, or gnawed on wood to sharpen their teeth. Moths may have made holes in textiles to use as cases for their larvae or as sustenance, and beetles may have eaten fur, feathers or wood. Note that different insects eat different objects, so they may not be the same in every store throughout your organisation.
