Sustained Scratching in One Area Squirrels in some cases carry nuts into attics and effort to bury them in the insulation. Once they survive the insulation to the drywall, they may keep on "digging". They likewise like to tunnel and dig in the insulation to develop dens and take a trip tunnels. If Found Here goes through the insulation to the drywall while tunneling, this can be heard in the room listed below.
Raccoons are the largest, heaviest attic intruders and I routinely remove them from attics. A lot of individuals underestimate the frequency with which they get into attics. Usually, female raccoons are fairly quiet in the early stages of the denning procedure. But as the kits begin to grow larger they make a lot more sound.
Once they reach a specific stage in their advancement, they start to tussle and battle. If the noise is heard in the springtime, this is probably the case. If heavy thumping is heard in the winter season it might be some kind of adult interaction. The 2nd largest species that invades attics is Grey Squirrels.
If the squirrel makes a leap from one point to another, it can create sufficient kinetic force to create a heavy thump. Generally though, squirrels are more likely to make pitter pat foot actions, scratching, and perhaps grinding noises as they chew on woodwork. Soft Mewing In the Attic, Soft kitten-like mewing sounds in the attic can indicate the existence of a very young raccoon litter.
Squeaking or Chirping in the Attic, High pitched chirping frequently indicates the presence of bats. I inform my consumers that bats vocalizations are high and metal and really quickly. They are very "cricket like" however with a much faster tempo. If the noise has a slower pace and is heard numerous times in succession it might also be a raccoon though I would describe raccoon sounds as more of a "chirring".
