Pelleted Droppings

Bats often defecate when leaving the building they are living in. Sometimes you can see droppings caught in spider webs too. Bat droppings will tend to be in piles in the attic below where they roost during the day. WARNING: Don't enter attics without wearing proper protection, which includes but is not limited to, HEPA Filter Mask, rugged gloves, long pants, and good lighting. Make sure masks are properly fitted and that you are healthy enough to breath with a mask.

Caterpiller Droppings

These tend to be squarish and cubed, but they can be easily confused with bat droppings. Often found in piles along vinyl sided buildings.

White-tailed deer droppings are found in piles, much like those of llamas and elk.

Elk Droppings (Cervus elaphus nelsoni)


Elk droppings occur in piles, the same as done by deer and llamas. Elk droppings are larger than deer droppings. Note the U.S. Nickel in the photo on the left side of the image. Elk droppings. Photo by Stephen Vantassel  

Mouse droppings (Mus musculus)

Tend to be black (hard when dry) pointed on one end and about 1/4-inch in length. Found in scattered patterns in high traffic areas.

Flying Squirrels

(Tribe: Pteromyini)

Warning: Never enter an attic without proper protection. Flying Squirrel excrement has been known to contain typhus.

Top Photo: Note how the droppings appear moist. This photo was taken of the area directly below the attic vent the flying squirrels were using to exit and enter the building.

Bottom Photo: Note the subtle staining in the soffet.
