Rodents aren’t smarter than A1 Exterminators.
When inspecting for mice or rats, an A1 Exterminator technician will look for rodent burrows, holes in the ground where rodents nest and create an underground tunnel around dumpsters, homes or buildings. Another sign for mice or rats are “rub marks,” which is the dirty and oil from their skin that rub off and leave a funky smell, on the surfaces which rodents frequent.
