What Do Mouse Droppings Look Like?

So What Do Mouse Droppings Look Like? If you suspect you have a rodent infestation, you will want to know for sure one way or the other. Mice are exceptionally fertile creatures – they reach sexual maturity at just a few weeks of age and pregnancies last around twenty days. With each litter consisting of up to fifteen mice pups and females able to become pregnant again within twenty-four hours after giving birth, it’s easy to see how quickly mice can become a problem. 

How Can I Tell If I Have a Mouse Infestation?

If you have seen a mouse in your home, it is likely there will be others. Mice live together in nests, often in dark, warm areas such as behind skirting boards, in airing cupboards, or behind kitchen appliances such as refrigerators, washing machines, or ovens. Each nest can be home to up to two dozen mice. 

As they will need a food source, kitchens and pantries are especially inviting to mice. You can reduce the chance of them coming into your home by storing food in airtight glass, metal, or plastic boxes and being vigilant when cleaning to get rid of crumbs and other temptations that are attractive propositions to mice. Do not leave pet food out at night for your furry friends – this will attract scavenging mice.

You may not see mice, but still suspect they are in your home. As mice are usually nocturnal, they become more active at night, which is why it may take a while to realise you have unwanted visitors in your house. However, there will be signs. You could find gnaw marks on the woodwork in your home. Perhaps you have heard rustling noises in your loft or noticed signs of books, papers, or food being nibbled at. Mice often collect paper and wrappers to build a cosy nest, which is why these signs of destruction may be evident around your home. With sharp teeth and a tendency to gnaw, mice often chew through wires and cables. This is not only frustrating but potentially very dangerous as it can cause fires. Regularly check behind furniture and in dark spaces such as lofts, cupboards, and in the eaves of your property – far better to catch mice quickly rather than being overrun with them. If you notice considerable damage in one area, the nest is going to be nearby. You may also find evidence of mouse droppings.

What Do Mouse Droppings Look Like?

If you’re not familiar with mice, you may be wondering what do mouse droppings look like? Mouse droppings (mouse faeces or poop) are small but big enough to easily spot with the naked eye. The hard pellets are usually ¼ inch in size or less (around the size of a grain of rice). Dependent on the diet of the rodent, the tips of each dropping may be pointed. They are black or dark brown and are usually found in random clusters. This is because mice discreet between fifty and eighty droppings a night and as mice live in colonies in their nest you will probably find multiple droppings.

What Should I Do If I Find a Mouse Dropping?

If you find a mouse dropping (or, more likely a cluster of droppings) it is important that they are disposed of correctly. This is because mouse poop can harbour a variety of diseases and pose a health risk. Hantavirus Pulmonary Syndrome is an airborne virus that is spread via rodents’ droppings. Flu-like symptoms such as dizziness, aching muscles and high fever can make those infected very unwell. Lymphocytic Choriomeningitis is another disease spread via mouse droppings – a severe and sometimes fatal illness with symptoms such as paralysis, meningitis, and encephalitis. Always seek medical advice if you are ill after contact with mouse droppings.

As droppings can spread disease to humans, always clean them up in a well-ventilated space – open windows and doors to let air flow through the room – and wear disposable gloves and a facemask for your own protection. Bleach the area and leave for fifteen minutes before soaking up with a paper towel/kitchen roll. Carefully bag up all materials and dispose of them in the waste. Do not use a vacuum cleaner to hoover up the droppings as this can create more dust and spread disease. 

Could It Be Rats Not Mice? 

Rats can come into your home and many of the signs of their presence are similar to if mice were in your home. As rats are larger rodents, any holes may be bigger. Rats burrow along and underneath properties so look for channels near outdoor walls where they’ve been digging. This tendency for digging can cause serious structural issues for buildings, which is why a rat infestation should be dealt with promptly.

What Do Rat Droppings Look Like?

In the rat v mouse droppings head-to-head, the main difference is size. Like mice droppings, rat droppings are thin, cylindrical droppings that look like a grain of rice. Dark in colour, they are larger in size than mice poop. Dark, shiny droppings are fresh whereas dustier, grey-brown poop is older. As rats mark their territory through faeces and urine, if you notice these tell-tale signs around your home, it is likely a rat is nearby.

Rat vs Mouse Droppings

The two droppings are very different. Rat droppings are typically larger and contain more urine. Mouse droppings contain less urine and are smaller, which makes them more difficult to spot. It can be difficult to differentiate between rat droppings and mouse droppings because both of them look quite a lot alike.

The main difference between rat droppings and mouse droppings is the size and amount of liquid they contain. Rat droppings are much bigger, around 1cm-1,5 cm long and have a lot more liquid than mouse droppings do. Mice droppings size is around 4mm-7mm.

What Should I Do If I Find Rat Droppings?

If you find rat droppings, follow the same cleaning procedure as for mouse droppings, remembering to wear protective clothing such as gloves and a facemask as rat poop is hazardous waste.

There Are Rodents in My Home. How Can I Get Rid of Them?

Once you are aware you have rodents in your home your top priority will be getting rid of them. Not only are they harmful to health and damaging to your property and belongings, but there is also a stigma to having rodents in your home. Call in pest control specialists and ask for their advice about the best way to deal with the problem. With the speed rodents breed at, act promptly. They won’t leave of their own accord and delaying getting assistance will only mean more rodents.

One way to deter rodents from your home in the future is to get a cat. They will be put off by the scent of the feline who will also catch mice and rats before they have a chance to breed and leave you overrun. Rodents will be fearful of any animal larger than themselves, seeing them as a threat. However, be aware that a cat may catch and kill a rodent, leaving them as a parcel for their owner, so this might not be the answer if you are squeamish.

Remember the importance of cleanliness. A clean kitchen, pantry, and food storage space leaves rodents with no access to a food source. If they can’t find anything to eat, they will move on. Get rid of any clutter such as papers and excess clothes stored in lofts – rodents will see these as a perfect warm place to set up a nest. Chemical scents can be off-putting for rodents so using products such as bleach when cleaning can act as a deterrent and as well as ensuring your home is free from nasty germs.

Other Household Pests to Be Aware Of

Rats and mice are common pests but there are many other creatures that can cause damage and spread infections within your home. Squirrels can take up residence in lofts and eaves causing major damage to the structure of your property – like other rodents they may chew through wires making them a potential fire hazard, too. If you have an outdoor space or a shed these can also be popular places for rodents to nest, so don’t only look for them in the house. Foxes, birds, badgers, moles, and other wild animals can also cause damage to sheds, outhouses, and garages so it pays to be aware of the animals you are sharing your space with.

Small pests such as bedbugs, fleas, and carpet mites can be brought in on clothing, furniture, or pets and cause allergies and illness to humans living in the house. Moths, wasps, and insects can also cause issues, especially damaging upholstery, clothing, or soft furnishings. As with larger unwanted pests, acting quickly is a must to nip the issue in the bud so search for specialists who can give you advice tailored to your own situation.

Having an awareness of the pests that may be in your home and the clues to them being in your property can be incredibly useful. Remain vigilant and make time to thoroughly clean and tidy your home to ward off unwanted pests. Creating a hostile environment for them is the best action you can take as prevention is better than the cure, especially as pests have a nasty habit of quickly reproducing. In the case of an outbreak, act quickly and thoroughly and remember that pests are a common nuisance to homeowners – although there is a stigma attached to having an infestation of rodents or other pests, you are not alone.
