Do you know if you have a rat or mouse problem? Rats are more significant than mice and have a scaly tail, oversized ears, and blunt noses. Mice are characterised by their more diminutive stature, pointed muzzles, small ears, and smooth tails. Read on for more information about identifying the type of rodent that has invaded your home or business.
What Distinguishes A Rat From A Mouse?
Detecting The Odour
The urine of rodents is one of the most obnoxious and apparent signs of an infestation. Mice's urine has a distinct odour, but it's not nearly as strong as the odour of rat urine. Seeing the difference may seem like a mystery. Let's say instead of mice; you have rats in your pantry when it starts smelling like old cheese.
If the infestation has reached the point where you can smell the rodents in your home, it may be futile to argue over which rodents are responsible for the scurrying sounds. So call us if you want your house to stop smelling like a garbage dump.
Size
Spotting the scurrying rodents is a surefire way to tell the difference between a rat and a mouse. Rats can reach a maximum length of 18 inches, while mice typically top out at 4 inches in length, including their short tails. We know you're rolling your eyes already, but it's worth remembering that even if you can't see the rodents, you might be able to tell something is up by looking at their droppings.
Skull And Paw Prints
The distinctive chew marks can identify both mice and rats they leave on food and furniture. Holes made by rats' teeth are more noticeable on packages and surfaces than those made by mice. The presence of mice can be inferred from minor scratches and chew marks.
Keep an eye out for cables and other obstacles in the home. Unlike rats, mice are more likely to avoid damaging your furniture when searching for nesting materials. Rats can gnaw through many materials, including cable, drywall, and even wood, so any signs of damage to these materials should raise suspicions that you have a new rodent roommate.
Appearance
Mice found in homes are typically much smaller than rats. Between four and six inches in length, they can be any shade of white, grey, or brown. In general, their bellies are paler than the rest of their bodies.
Norway rats, the largest and heaviest species, are nearly twice as long as the standard house mouse. Norway rats are more significant than average rats at around 10 inches in length. They have shaggy brown fur with black shading all over their bodies. The size of its tail is significantly less than the length of its body, making it a distinctive identifying feature. Their noses are less pointed, and their ears are more diminutive.
Roof rats, on the other hand, reach eight inches and have a leaner, more muscular build. They have soft grey fur with black shading all over their bodies. Their rat tails are longer than the rest of their bodies, setting them apart visually from the Norway rat. In addition to their pointed noses and large, erect ears.
Since rodents are nocturnal, it can be challenging to spot one and identify it based on its appearance alone. However, there are several ways to identify the rodent species invading your home. Instead, it's best to have a professional come out and assess the situation, determine the rodent species responsible for the infestation, and recommend a course of action.
Diet
Mice and rats in the house have specific diet requirements but will eat almost anything they can get their snouts on. There may be clues to the rodents' identities in the gnaw marks or other signs of feeding damage found on food sources.
Cartoons may have you believe otherwise, but grains, fruits, and seeds are some of the mice's favourite foods. These carb-lovers might eat all of the cereal you have on hand. Mice in the house can get the water they need from the moisture in their food, and they only need to drink about an ounce of water daily. In general, Norway rats prefer the same foods that house mice do, with the addition of meats and fish. They require about an ounce and a half of daily water when fed dry food.
The eating habits and routines of roof rats are unique. Roof rats can be identified by hollowed-out fruit on the ground near any fruit trees in your yard, as this is one of their favourite foods. In addition, they consume grain in a manner that is distinct from other cultures. If they've been feasting on it, you might find bits of grain that look like they've been halved. They consume about one ounce of water per day. They are more difficult to trap and bait because, unlike Norway rats and house mice, they move around frequently in search of food.
You should also empty any containers outside that collect rainwater for drinking, keep your kitchen and sink clean, and store all food in airtight containers indoors.
Managing Rats And Mice
You may be wondering what to do about rodents in your home, whether they be rats or mice. If you keep your house clean regularly, rodents won't be able to find the food they're looking for in the trash or anywhere else you might have recently stored food. Rats and mice can be discouraged from seeking shelter in your home by doing something as simple as keeping the floors swept regularly.
The presence of excess moisture will attract rodents, so it's essential to check your pipes for leaks. Be sure to put a lid on anything you keep out of the fridge. Some rats may still be able to open packages, but if food is left out or improperly sealed, the rats will have an easier time getting to it. Finally, it is essential to seal up any openings or cracks in your home. Rodents will find gaps in your windows and walls and enter your home when you least expect it.
Habitat
All three rodents will gladly make your house or yard their new home. Each species' unique climbing capabilities dictate prefered habitats, nesting sites, and points of entry into human dwellings.
House mice have excellent climbing abilities, greatly expanding their range of potential habitats. Nesting sites include empty spaces in walls, attics, storage containers, cabinets, lofts, crawlspaces, basements, barns, sheds, and similar outbuildings. They collect pliable items, like shredded paper, to use as nesting material. Norway rats construct underground nests and those in attics, basements, and crawlspaces. Your property's barriers, tree roots, woodpiles, the ground beneath structures, and densely overgrown weed patches are potential habitats for them. They frequent drains and eat the insects that live there. The roof rat is a skilled climber that selects nesting sites in the canopy of a tree or the upper stories of a structure.
Breeding
It doesn't take long for rodents to have litters of offspring, so if they're already in your home, keep an eye out for newborn rats and mice. All newborn rodents are hairless and blind and must rely on their mothers for survival. Reproduction rates in the house are much higher than those of rats. In about 8-12 weeks, the young mice will mature into sexually active adults. Rats in Norway have four to six litters a year, each having anywhere from six to twelve babies. Around three months of age, they reach sexual maturity and can start reproducing. Roof rats have five to ten litter per year, each consisting of five to ten young.
Risks And Damage
The situation at hand calls for a comprehensive approach, regardless of whether the pest in question is a mouse or rat.
Mice-Induced Destruction
Mice can chew through wood, insulation, and even walls if given a chance. They pose a fire hazard by chewing through wires and causing electrical problems. Mice will use cardboard and plastic food containers as nesting material despite efforts to deter them.
Humans and animals alike are in danger from the diseases that mice carry. It is estimated that a single mouse can produce anywhere from 50 to 100 droppings in a single day. Listeria, salmonella, and hantavirus can all be transmitted through mouse faeces.
Rats Cause A Lot Of Problems
Giant rats are a common problem. They can only move around and nest in large, open areas. You will devour anything in their path. Rats, despite their size, need only half an inch of space to enter, and they can chew to enlarge entrances further.
Infested rats will eat through your food storage very quickly. Mice and rats can gnaw through virtually anything. Rats tend to only eat from one particular type of food. If they find a good one, they will most likely stick with it.
Rats can carry deadly diseases. Diseases like hantavirus, rat-bite fever, and even the plague can be transmitted through a rat's bite, droppings, or the fleas those rats carry. These diseases have the potential to cause life-threatening complications.
Pest Control Challenges: Mice Vs. Rats
The two rodents, the mouse and the rat, are very different. Different pests require different approaches, so eradicating one may worsen the other. It would help if you learned how to deal with rodent infestation through pest control.
You can determine the best method for eliminating a rat or mouse population by pinpointing their nesting spots, food sources, and entry points. Mice are adventurous and curious, while rats are wary and timid. Their reactions to lures and baits will vary. So, while a rat might try to avoid a trap, a mouse might walk right into it.
Without comprehensive population control, the problem can quickly resurface. Mice and rats will continue both breeds rapidly to replenish their numbers. Choose a partner that can provide comprehensive pest management. It includes reducing the existing population and blocking new rodents from entering the building.
The only way to prevent rodents is to find every possible entry point and seal it with a material that can withstand even the most determined rodent. More robust materials are needed to trap and kill rats effectively. Standard options for keeping rats out of a building include galvanised steel and cement, while other materials might do the trick for mice.
Raccoons Are The Worst In Every Way.
If you can't tell if you have mice or rats, it's probably mice. Rats are almost a foot long (not including the tail), making them much more noticeable than their smaller relatives. They are also noisier, more gluttonous, and stinkier.
Droppings
The adage goes, "If there's rice, there must be mice." This catchy rhyme describes the size and shape of mouse faeces, while rat faeces are significantly larger, measuring between a quarter and a half an inch.
Mice defecate as they forage, while rats are more likely to choose a single spot for their bathroom needs.
Noise
Rats are vocal communicators, too. They have a louder and more diverse language than mice, which often consists of ultrasonic squeaks (outside the range of human hearing).
Distinctive Behavior Modifications In Rats And Mice
Mice can survive without drinking water.
Unlike rats, mice don't need a constant water supply because they can get all the moisture they need from their food.
Rat infestations are thus closely linked to plumbing issues such as clogged drains and dripping pipes.
Wise rats are challenging to catch because they are wary.
Rats' neophobia, or aversion to novelty or change, is an adaptation that has helped the species thrive.
Because of this, catching them is challenging because, unlike mice, rats will avoid any traps set down. We wait weeks between rat visits because trapping them requires patience and the passing of the neophobia period.
Rats are commonly introduced to buildings by force.
Mice can thrive and hide within our buildings because of their small size, but rats are not fond of human company and prefer to make their nests in sewers or abandoned buildings.
If there are rats in your building, we will first try to determine whether or not the infestation is the result of an outside force, such as construction or clogged drains.
Rats And Mice Respond Differently To Treatment
It's Not Right To Poison Rats.
Desiccating poisons (not to be confused with store-bought toxins, which we do not recommend) work well on mice because of their small body size, preventing the carcass from rotting or smelling.
Preventing rat infestations requires regular drain inspections.
Drain inspections are a standard part of our assessment, control, and prevention of rat infestations because rats commonly nest in drains and venture up into buildings in search of food.
We instal CCTV cameras in your drains to catch those pesky rats before they enter your home or business.
Since mice prefer to live inside rather than in the building's drains, checking the gutters isn't necessary if you suspect an infestation.
Conclusion
When comparing rats to mice, remember that the latter have pointy noses while the former have rounded ones. Mice faeces are more like pellets than grains of rice, while rat faeces are about half an inch long. Contact us for assistance identifying the species of rodent invading your home.

Frequently Asked Questions
Appearance. Rats are more significant than mice and have coarse fur that can be red, brown, grey, or black (depending on the breed) and a long, scaly tail lacking hair. A full-grown rat can be anywhere from 11 to 19 inches long (including the bottom) and weigh half to one pound. Mice have big ears but small, black eyes.
Nesting areas for rats are common in attics, lofts, under eaves, and even cavity walls. Rats will shred anything soft they can get their gnawing teeth into, including loft insulation, cardboard, and other delicate items.
Rats will leave the nest as soon as it has been disturbed, whether by a human or another animal. Another possible explanation for daytime rat sightings is that the nest is close by, and the rats must cross the garden to get away from the nest.
Most commonly, they'll conceal themselves in places where they won't be disturbed, such as the spaces between walls, pantries and cupboards, behind sofas and old boxes.
When seen during the day, rats are most often found in gardens or other outdoor areas. Although they may be making their way from one park to another, rats are notoriously resourceful. You can find vegetables, nut and fruit trees, and other sources of nutrition in backyard gardens and orchards.
