If you're inclined to going into the attic on your own to try and determine what kind of animals are up there making noises, be sure you know what you're getting into first. Unless you have a certain level of experience navigating through attics, this approach can be considerably dangerous. Animal Rangers technicians are highly experienced conducting inspections in attics and crawlspaces for animal activity.
Is there a bad odor or smell something fowl coming from your attic?
Prolonged activity with animals in the attic will often cause pungent odors from urine and feces. Fowl odors from animal waste may begin protruding into the living space if an ongoing infestation has been occurring over time. Breathing in potentially hazardous mold spores from animal feces can potentially cause respiratory illnesses, so it is important to wear a respirator when going into an attic with bad odors caused by animal waste.
