Rats and mice are some of the most common pests in the world. These furry little rodents are known for their love of food and ability to reproduce quickly. Mice and rats are attracted to homes because they offer warmth, shelter, and an abundance of food. As a result, these pests will build their nests in many places, including attics, walls, crawl spaces, and inside furniture.

If you suspect a rat or mouse infestation in your home, it is essential to take action immediately. These pests can cause extensive damage to your property and spread diseases to humans and animals alike. But how do you recognize when you have a rat or mouse problem? This article will explore a few signs you need to look out for.


If you see small, black pellets around your home, you likely have a rat or mouse problem. Rat and mouse droppings look different, but both can pose health risks. Rat droppings are usually dark and cylindrical, while mouse droppings are smaller and more pellet-shaped. Both types of droppings can contain harmful bacteria that can cause serious illnesses in humans. Droppings should be cleaned up using gloves and a mask to avoid exposure to bacteria. After that, call an exterminator immediately.

Gnaw Marks

Rats and mice are both known to gnaw on things, but what does this damage look like? Rat and mouse gnaw marks can vary depending on the size of the rodent and what they’re gnawing on. Generally, rat and mouse gnaw marks will be small and have sharp edges. On wood, for example, you may see tiny grooves that are evenly spaced apart. On the other hand, you may see tears or holes on softer materials like cloth or paper.

If you suspect that you have a rat or mouse problem, it’s crucial to inspect your home for evidence of gnawing. Pay close attention to any food packaging that’s been damaged or any holes in walls or floors.


One tell-tale sign is finding actual footprints if you think you might have a mouse or rat infestation in your home. These rodents are nocturnal creatures, so their footprints are often found in areas with a lot of dust or where there has been recent activity, like in a pantry or near the trash can. Rat footprints will look different than mouse footprints, and knowing how to tell them apart can help you determine the severity of your infestation.

Mouse footprints are small and round, about the size of a dime. They usually have four toes on the front foot and five on the back foot. If you see these prints, you likely have a few mice.

Rat footprints are larger, about t3/4 to 1 inch. Rats will also leave drag marks where their tales drag on the floor dust.


Rat and mouse nests are usually made out of whatever material is available to them. This can include paper, cloth, insulation, and even twigs and leaves. The nest size depends on the number of rats or mice living in it, but they are typically around 12 inches in diameter. The inside of the nest is lined with soft materials like fur or feathers to make it comfortable for the animals. Rat and mouse nests are often found in attics, crawl spaces, and other areas where they can be hidden from predators.


When you hear a rat or mouse in your home, it can be hard to tell which one it is. Rats tend to be larger than mice, so their noises are usually louder and more noticeable. If you hear scratching sounds coming from your walls or ceiling, it’s likely a rat. You might also hear them gnawing on wood or chewing through insulation. Mice are smaller, so their noises are usually softer and less noticeable. If you hear faint scratching sounds coming from your floors or baseboards, it’s likely a mouse. You might also hear them squeaking as they run around.

In conclusion, call a professional if you have any of these common rat or mouse signs in your home. Rodents can cause significant damage to your home and can pose health risks to you and your family. Don’t wait until it’s too late; call Target Pest Control today.
