What does a rub mark indicate when found in an area?

A rub mark indicates that rats have repeatedly passed by and brushed against a surface. This phenomenon occurs because as rodents travel through their territory, their fur may rub against vertical objects, leaving behind visual or greasy marks.

These marks are particularly useful for pest control professionals as they provide important clues about rodent activity and movement patterns. By identifying rub marks, pest professionals can ascertain areas of high traffic, which can be critical for determining where to focus control efforts. Distinguishing these signs helps in developing an effective management plan for rodent infestations.

Other choices describe different animal behaviors or indicators that do not accurately correspond to the presence of rub marks, which are specifically associated with repeated contact of rodents with surfaces in their environment.
