Rodent Runways
Runways are usually evident in rodent infestations because rodents repeatedly use the same pathways between their nests and food sources.
Runways or Pathways
Common linear pathways include foundation or sill ledges, tree branches, electrical lines, pipes and sewer lines.
Mice typically travel 6-30 feet from their nests to a food source. Rats are more adventurous and will venture out 25-100 feet from burrows.
Rub Marks
These grease marks are created from oil and dirt on the rodent's skin and often appear along wall areas next to runways.
