Do you think there is a mouse in your home?

Are you confused because you have detected some droppings in your house and you don’t know which animal it is?

Is it of a mouse or something else like rat or a cockroach? Will touching these mouse droppings make you sick?

Well, if you want to know how you can identify the mouse droppings and what should be done about it, I will try to explain in this article.

Briefly, in the below article, I will cover – what do mouse droppings look like and how can you deal with them safely?

What Does Mouse Poop Look Like?

How its different from the droppings of rats, roach and bats?

The very first thing you should remember is mouse poop looks different from that of rats and cockroaches due to the shape and size.

Typically, a mouse in your house produces between 40 to 100 droppings per day.

The feces of the mouse are small – around 1/8 to 1/4 inches long and sleek. They look like a dark brown rice grain tapering towards the ends.

On the other hand, the feces of rats are ¼ to ½ inch in length with round ends. 

And the poop of a roach is a tiny black speck that looks more like grounded coffee or black pepper.

If you have large size roaches in your home, then their feces look like dark-colored cylinders with ridges all over and they are comparatively shorter than mouse droppings.

If you also have bats around your property, differentiating between bat poop and mouse feces may be tough.

To tell them apart, you will need to focus on the consistency rather than their shape and size.

While mouse feces are solid and thick, bats excrete can be crushed to powdery form easily.

Will It Be Hard or Soft?

When it’s about how the mouse poop appears, it’s good to know that their appearance varies depending on whether it’s fresh or dried.

Naturally, the fresh mouse droppings will always look wet and appear to be soft and moist. Plus, if it is newer it will be darker and shinier.

On the other hand, mouse droppings that are not fresh (few days to about a week old) will appear to be dull, chalky, dry, and harder.

Remember that the color of the droppings will also depend on what the mouse has eaten inside your home.

Also, most mouse droppings will tend to look off-white after about 48 hours. You will also see them crumbling when touched.


Is Mouse Poop Dangerous to Humans?

In simple short words yes, the feces of a common house mouse can be dangerous for humans!

Mice and their droppings in your house may carry diseases such as hanta-virus, salmonellosis, hemorrhagic fever, lymphocytic choriomeningitis, and leptospirosis.

And the fact is an infected mouse can send these diseases to others through their urine or droppings.

Some of these diseases can be transmitted to humans as it sticks to the dust and airborne particles.

If anyone in the family touches the contaminated dropping, they may get infected from these deadly diseases.

Mouse poop is thus considered hazardous for family members and even for your pets.

What are the other threats?

Apart from the threats of their feces, mouse themselves are a dangerous animal.

If anyone touches a mouse or has got bitten by it, then it is likely that the virus or bacteria may spread.

If a mouse has entered your pantry and contaminated the food, you have a high chance of getting infected.

Mice can carry ticks and fleas to your home. Ticks have bacteria that cause Lyme disease and viruses which can infect you or your pet.

Mice also pose threat to your property, wood furniture and particle boards.

They can also chew your electrical wires which may lead to short circuits or even fire in the building.

Places You Can Find Mice Droppings In Your Home

If you are worried about mouse infestation in your house, then the very first step to getting rid of them is to find the mouse feces behind.

Mice poop in large quantity, so even if you haven’t seen a mouse, their pellets will reveal the story behind.

You will commonly find their dropping near your stored food.

In general, any food sources like trash bins, pantries, drawers, or kitchen closets will work like a magnet for them.

The other common places where you are likely to discover mouse feces are bathroom cabinets, small hideous areas, closets, air vents, small holes in walls, etc.

Mice look for warm places to stay, hence you may also find their droppings near appliances that are hot such as microwave, refrigerator, etc.

You can notice their poops below your furniture too. Additionally, they also reside in the ceilings, walls, attics, garage as well as the basement.

If you like late-night snacking, most probably you may notice mouse pellets next to your bed in the morning.
