Fresh mouse droppings are squishy and slimy when fresh and turn hard when old (see All About Mouse Poop!). Another clue for you is that bat droppings are usually found in piles while mouse droppings are scattered but not generally in piles. Read more
British bats are entirely insectivorous and so their droppings only contain the indigestible parts of their insect prey. This content gives their droppings a crumbly texture which allows them to be differentiated from mouse droppings, which look similar but become very hard when dry.
Signs That Bats May Be In Your Home Include:
Noises in walls: This may be a sign of mice or rats, but mice and rats are usually quiet if you thump on a wall. Give your wall a thump. If you hear a reaction from the other side, it is likely that you have bats. Night chirping noises: Bats make chirping noises.
Bat poop is about the size of a staple and about 1-3 cm in length; Bat or Rat poop will look a lot like a black seed. Bat poop or bat feces is generally black. If the poop is very dry and brittle chances are that the bat poop is not fresh. If the bat droppings are very soft and mushy then chances are it is very fresh.
The droppings are typically black in color, and when they are found separately they are long thin pellets, but it is the reality that they collect in piles that actually assists bat feces to stick out.
Bat droppings, also called guano, are slightly smaller than rat droppings and are similar to a long, black grain of rice. These droppings will be found in large quantities under where a bat sleeps or sits.
A bat poops out of its anus. Bats need to be upright in order for the poop to easily drop from the body. Bats most often poop while flying. They may also rest on a perch to relive themselves.
And one other thing you can count on is that bats will leave guano droppings on the entrance to their roost area every night. These droppings may accumulate on a wall, windowsill, or porch, or other place directly below the place where the bats are entering your home. Guano resembles mouse droppings only larger.
Cockroach poop, cylindrical, solid feces, is often mistaken for mouse droppings.
On some occasions, chipmunk droppings can be spotted on patios, in sheds, and in garages but are commonly thought to be mouse or rat poop. This is because all of these rodents produce pellet-shaped feces that are about the size of a grain of rice.
To clean up small quantities of droppings
Use a low-pressure stream of water. Clean up the droppings using soapy water and a mop or cloth. Disinfect affected surfaces with a bleach solution (1 part bleach to 9 parts water). Leave it on for 10 minutes before rinsing and wiping.
Rodent droppings are a good indicator of the pest in your house. Rat droppings are shiny black and 1/2 - 3/4 of an inch long, whereas mice droppings are small and smooth with pointed ends. Chew marks are another telltale sign to distinguish your rodent.
Squirrel droppings closely resemble rat feces. Both pests' poop is dark brown and smooth, but squirrels leave larger, barrel-shaped pellets behind while rats produce small, oblong-shaped droppings with tapered ends.
Bat droppings are commonly found on the side of your house, at the bottom of an entry point (window sill, porch, ground), and in the attic. You'll often find a pile of guano on the insulation in your attic underneath their perch. Bat Guano has a strong smell of ammonia.
In some extreme cases of a bat infestation, the smell of bat guano and urine is very musty and can resemble the smell of ammonia. It can be hard to detect in your home, as the smell will gradually grow in your home.
Mice droppings are typically small, about ¼-inch in length. You can tell if they are fresh droppings by the color. Newer droppings will be darker and shinier while older droppings will look chalky and dry. Rat droppings are similar in shape but larger, typically ½-inch to ¾-inch in length with blunt ends.
Clean the area with disposable rags or paper towels. Put the mouse droppings and disposable cleaning supplies into a plastic bag; seal it well. Place the sealed bag in a covered trash can, and take out the trash as soon as possible.
Bats don't have an anus and they poop through their mouth.
Microbat. If you have microbats living in your roof or chimney, you're likely to see their poo lying around. It's very similar to mouse poo in size, shape and colour, but the consistency is much drier.
Histoplasmosis is caused by Histoplasma, a fungus that lives in the soil, particularly where there's a large amount of bird or bat poop. The infection ranges from mild to life-threatening. It can be misdiagnosed because its symptoms are similar to those of other illnesses, like pneumonia caused by bacteria.
Dampen the Bat Feces
In a low-pressure sprayer or spray bottle, mix equal parts of hydrogen peroxide and ammonia in water. Moisten the droppings generously to avoid creating any powder residue when you remove the guano.
The problem begins when dried bat guano is disturbed and "bat guano dust" is created in an attic. When these microscopic spores from the dried bat guano are inhaled by humans they can cause a serious respiratory disease called histoplasmosis*.
