Rats are cunning creatures, so assessing the severity of an infestation can often be difficult. Counting the number of rats in your home is not straightforward, as they typically hide from people. However, you can use various other methods to estimate the number of rats in your house.
If you follow the strategies outlined in this article, you can effectively determine the extent of the infestation and proceed to eliminate the rodents.

How to tell how many rats are in your house
You can look for several signs to determine how many rats might be in your house. A small rat colony may consist of only a few rodents in urban areas. However, if the available food and shelter can support a larger population, more rats are likely to join the colony. Some colonies can sustain dozens of rats.
Here are some signs that will help you determine the severity of a rat infestation:
- Check the number and size of rat droppings: The number of droppings can give you an idea of how many rats are in the area. The presence of rat droppings in different sizes indicates a mix of younger and older rats. This suggests that you may be dealing with a more extensive rat infestation;
- Inspect gnaw marks: Check for gnaw marks on wood, plastic, or other materials that rats may have chewed on. The number and size of the marks can give you an idea of how many rats are present.
- Look for singular or multiple track marks: Look for footprints or tracks in dusty or muddy areas, which can help you identify the size and number of rats. Using powder (such as flour) in areas where you have noticed rat activity can help you determine if the activity has increased. This will also confirm the path rats use to move through your house. Finally, you can also better understand where rats are most active if you decide to set up traps later.
- Listen for strange noises: Listen for scratching, scurrying, or squeaking noises in walls, ceilings, or floors, especially at night when rats are most active.
- Look for nesting sites: Check for nests or burrows in walls, attics, basements, or outdoor areas. The number of nests can give you an idea of how many rats live in your house. If you come across an empty rat nest, it’s possible that you discovered it before the rats gave birth.
Signs of rats in the loft
Rats often find lofts to be a suitable nesting space, providing a safe environment to rest during the day and materials to gnaw on and use for their nests.
- If you hear scratching or scraping noises from your loft, it’s possible that rats are present;
- Gnawed wires, boxes, or pipes;
- Small brown droppings and tiny footprints in dusty areas;
- Rat holes leading to other parts of the home or outside;
- Shredded insulation that may be used for nests;
Signs of rats under decking
Rats may find shelter under decking during rainy days and may use it as an undisturbed and isolated space to build their nests. Additionally, since decking is often attached to homes, rats may have easy access to your property.
Signs of rats under decking to look out for include:
- Dark brown or black droppings shaped like grains of rice;
- Gnawed decking boards;
- Strange noises such as scurrying, scratching, and squeaking;
- Spherical nests made of materials like paper, cloth, or insulation;
Based on the number of droppings, footprints, gnaw marks, and other signs you observe, you may get a rough estimate of how many rats are in your house.
Learn How to Get Rid of Rats in Your Home
Where do rats come from?
Rats are usually attracted to areas where they can find food, water, and shelter. If you are dealing with a rat infestation, it is unlikely that you will spot the rodents themselves but rather the traces they leave behind. Here are some common sources of rat infestations:
- Nearby outdoor areas: Rats can come from nearby areas such as parks, fields, and garbage dumps in search of food and shelter.
- Neighbouring buildings: Rats can quickly move from one building to another, so if there is a rat infestation in a neighbouring building, they can easily move into your home or property.
- Cracks and crevices: Rats can enter buildings through small cracks and crevices in walls, floors, and foundations.
- Sewers and drains: Rats can live in sewers and drain systems and enter buildings through drains or sewer lines.
Rats are destructive and persistent, not the kind of guests you want in your home. They are adept at getting into our homes, living in attics and walls, and only coming out at night.
How many rats usually live together?
The number of rats living together varies according to species, food availability, and environmental conditions. Rats are social by nature, so they prefer to live in groups. The size of their colonies, however, could vary widely.
The ordinary Norway rat, for example, one of the most frequent species found in cities, usually lives in groups of up to 12 rodents. In rare circumstances, though, a larger population of rats may reside in a single burrow or nest.
Rats are prolific breeders and can reproduce quickly, thus if left unchecked, a small colony of rats can quickly grow and become a bigger infestation. You must act quickly to prevent the population from expanding and causing additional damage on your property.
How long does it take to get rid of rats?
It can take anywhere from a few days to several weeks to eliminate rats. The time depends on several factors, such as the infestation’s severity, the rat population’s size, and the methods used for rat control.
Using traps or bait is an effective way to control the rat population. But keep in mind that it may still take several days or weeks to reduce their numbers significantly. Additionally, it’s important to remove food and water sources, seal up entry points, and maintain proper sanitation practices to prevent the rats from returning.
A professional rat exterminator can evaluate the situation and create a rat control plan to stop the infestation in your home.
How do you know if rats are gone?
The absence of signs of rats can indicate that rats are no longer present and you are no longer dealing with an infestation. This includes:
- No rat sightings: If you do not see any rats around your property, it can indicate that the infestation has been eliminated.
- No rat droppings: The absence of rat droppings in and around your property can also suggest that the rats are gone.
- No signs of gnawing: If there are no signs of gnawing on objects around your property, it may indicate that rats are no longer present.
- If you cannot detect any signs of rats building nests in or around your property anymore.
By observing these signs and confirming their absence, you can be confident that the rat infestation has been successfully dealt with and that no rats are on your property. However, it is important to remain vigilant and take preventative measures to ensure that rats do not return in the future.
Will rats return to the same place?
Yes, rats can return to the same place if they like the conditions there. Rats are creatures of habit and tend to establish burrows and pathways in areas where they feel safe and can easily access food and water. Once they have identified a suitable location, they will return if favourable conditions remain.
Rats are also attracted to familiar scents, which can lead them to return to previously inhabited areas. Therefore, if you have had a rat infestation, preventing future infestations, such as sealing entry points, removing food and water sources, and practising good sanitation, is essential.
Additionally, rats are good navigators and can find their way back to a location using visual cues or their sense of smell. This means that if a rat has previously established a burrow or nest in a particular area, it may return to that location. Therefore, it is important to eliminate rats and implement effective prevention measures to discourage them from returning.
Takeaways
- You can estimate how many rats are in your home based on droppings, footprints, gnaw marks, and other signs you observe.
- Unchecked, a small group of rats can multiply quickly and can become a larger infestation if left unattended.
- Droppings of rats of different sizes indicate a mix of young and old rats.
- Rats are skilled navigators and can use their sense of smell to find their way back to a particular location.
