Dealing with pests in your home is frustrating, especially when you’re unsure which animals you’re up against. Mice and rats are two unwelcome visitors that share similarities, but key differences can help you figure out which pest is invading your space. Today, we’ll explore ways to know if it’s a mouse or a rat in your home.
Size and Appearance
The easiest difference to spot is their size. Mice are smaller, usually about two to four inches long, with thin bodies. They have long tails covered in fine hair that blends with their petite frame.
On the other hand, rats are much larger, growing to seven to nine inches or more. Their bulkier bodies come with thick tails, making them appear more rugged at first glance.
You can also look at the shape of their faces. Mice have pointed noses, while rats feature blunter profiles. Keep in mind that juvenile rats can sometimes resemble adult mice, but they’ll still appear more robust in build.
Droppings
With a bit of know-how, property owners can successfully identify pests by their droppings, including mice and rats. When it comes to rodents, know that mice have tiny droppings, similar to grains of rice, while rats have spindle-shaped droppings with blunt ends.
You’ll usually find rodent droppings along baseboards, in cabinets, or near food sources like your pantry. Mice tend to leave droppings closer to their nests or food, while rats may leave them along their travel paths.
Activity Patterns
Mice and rats come out at different times and for different reasons. Mice are curious and more likely to explore new spaces. They scurry quickly and leave smaller evidence trails behind them.
Rats act differently. They’re cautious and stick to well-known routes, which usually run along walls. They prefer dark corners and tend to avoid open spaces.
If you hear scratching from higher spaces like attic floors, it’s probably mice. When it’s rats, the sound usually comes from basements or lower parts of the house.
Habits Around Food
Mice and rats interact with food differently, and paying attention to habits can help you know which pests are in your home. Mice may nibble at several things as they don’t need much to feel full. Look for small bite marks on cereal boxes, bread bags, or cracker packaging.
Rats, on the other hand, eat more in one sitting and focus on high-calorie foods. They’ll drag larger food items back to their nests and have noticeably larger bite marks. If you notice entire food items disappearing, rats are likely culprits.
Sounds and Smells
Mice create high-pitched squeaks, faint scratching, and rustling noises. These sounds usually come from above or walls, especially at night.
Rats produce deeper, grating squeaks and heavier sounds of movement. The stench of their urine and larger messes also create a stronger odor. If certain rooms in your home carry a stronger unpleasant smell, rats may be the cause.
Nests and Nesting Materials
Mice construct small nests out of shredded materials like tissue, string, or paper. You’ll find these nests in tight spaces, such as inside walls or behind appliances.
Rats build larger nesting sites compared to mice and do so with heavier materials. You might find their nests made of twigs, insulation, or fabric scraps. They also tend to burrow and create deeper nests for protection.
