You may think mice and rats seem the same, and when you look at them, some of you cannot even tell them apart. The most prevalent rodents that you’ll find in your home are the brown rat, the black rat, and the house mouse.
All of them have sharp incisor teeth and have short legs and tails. But they are completely different in terms of their behaviors, habits, preferences, and features. But the biggest point of difference is their size.
So, if you have a rodent infestation at home and don't know which species has invaded your home, read this blog till the end to find out. This blog also discusses methods to effectively eliminate the rodent problem.
How to Distinguish Between Rats and Mice?
Here are several factors that need to be considered when identifying the difference between the two -
Identify by Looks
Despite their sharp teeth and small feet and tails, there are certain key features that help distinguish between the two -
-
Size: Mice measure about 3-4 inches long, and adults weigh less than an ounce. Whereas rats are longer, measuring 9-11 inches, and can weigh up to a pound as an adult.
-
Shape of the Head: The head of a mouse is sharp and appears smaller than its body. However, the rat’s head is broader and wedge-shaped, proportionate to its body size.
-
Fur: A mouse has soft, smooth fur in the shades of light brown, gray, or white. Whereas a rat usually has rough and coarse fur in tones of gray and brown, and even in black.
-
Feet: You’ll find the feet of the rat to be more robust with sharp claws, but the mice's feet are smaller and more delicate.
-
Tail: The tails of mice are slender and covered with fur that is almost the same size as their body. However, rats have thicker, hairless, and scaly tails, almost the same length as their bodies.
Identify by Poop
The first sign of infestation is their poop. It is advised to examine their poop to identify which rodent is invading your home.
-
Rat Droppings: Rat droppings are larger, measuring about 1/2 to 1/3 inches in length, and are brick-like or football-shaped. Roof rat droppings have pointed ends and are slightly curled. Also, their poops are fewer in number and is mostly found near feeding areas, such as cabinets, or in hidden areas, such as the basement.
-
Mouse Droppings: Mouse droppings are smaller, almost similar to grains, and measure about 1/4 inch long. Their droppings are scattered everywhere, near the food sources, along the way, and near their hiding space.
| Notes | No matter which rodent droppings you find, ensure to dispose of them with caution. Wear protective gloves and a mask, and disinfect the area with an EPA-registered disinfectant. This is because rodent droppings carry diseases harmful to human health. |
Behavioral Differences
Rats are considered more cautious than mice, and they avoid new items kept in their path. Whereas mice are more investigative and curious, which makes them easy to trap.
Living and Diet Differences
Mice feed on plants and grains and are known to build nests near food sources. While rats are mostly nomadic, and build nests underground, such as under buildings, under plants, and along fences.
When it comes to reproduction, female rats can carry up to 12 litters annually, and start reproducing at 3 months. They have a lifespan of 1-1⅕ years, and they usually reproduce in springtime. Whereas mice begin reproducing early, at around 6 weeks, and often carry the same number of offspring as rats.
Movement
Just like their diet and habitat, rats and mice can be distinguished based on how they move -
-
Mice: They can stand up on their hind legs, supported by their tails. They usually stand when they eat, fight, or look around. They are excellent climbers, jumpers, and swimmers. They can run on rough surfaces, wires, cables, and ropes, and can jump 13 inches high. Mice usually don’t like bright light, but they come out during the day to hunt for food.
-
Rats: Rats usually enter buildings through holes and crevices and are excellent swimmers. This means they can live in the sewer, drains, and toilets. They follow a similar pattern and path every day and will do anything to avoid obstacles in their way.
How to Prevent Rats and Mice Inside Your Home?
It is very important to prevent and eliminate rodent problems before they become a disaster. Here are some expert tips on how to keep them away from your home -
Seal All Entry Points
If there are any gaps, cracks, holes, or crevices in your home, that’s the entry point for rats and mice. It is advised to seal them with caulk or steel wool. Also, keep an eye on the windows, vents, and utility entry points.
Declutter Your Home
Avoid piling up cupboards, debris, and clutter, as they serve as hiding spots for the rodents. Also, if you have food leftovers, discard them efficiently as these attract rats and mice into the house.
Other Methods
Consider spraying peppermint spray at the entry point or the nesting areas. You can also use high-frequency devices to ward off rodents from your home. Additionally, you must keep in mind to clear leaves and trim tree branches, as these can get inside your home.
Address Water Sources
Be prompt in fixing leaks and addressing damp areas, such as walls, lawns, basements, etc. Also, make sure the drainage is proper and effective so that water doesn’t pool, as it attracts rodents to your property, which ultimately leads them inside the home.
Call a Pest Control
If you have done everything you could and the rodent issue still doesn’t seem to resolve, it is time to call a professional pest control company. Many exterminators use eco-friendly methods to help you get rid of rats and mice, as they understand, for example, how they look, how they behave, and more.
