Rats invading your home can be an incredibly frustrating and worrying experience. If you’ve noticed signs of a rat infestation, like droppings, gnaw marks, or nests, you’re probably wondering if the rats will just leave on their own eventually.

If you’re short on time, here’s a quick answer to your question: No, rats will not leave your home on their own. Rats invade homes in search of food, water and shelter. As long as these needs are being met, rats have no reason to vacate your property.

In this comprehensive guide, we’ll cover everything you need to know about rat psychology and behavior to understand why rats won’t leave on their own. We’ll also provide effective solutions for safely removing rats from your home for good.

Understanding Rat Behavior

Rats are opportunistic rodents that seek out shelter and food

Rats are highly adaptable creatures that have a knack for finding shelter and food in various environments. They are known to take advantage of any available resources, making them excellent survivors.

This is why rats often invade homes, gardens, and other structures in search of food and a safe place to nest.

According to the National Pest Management Association, rats can fit through small openings as small as a quarter of an inch, enabling them to access even the tiniest crevices in buildings. They are skilled climbers and can easily scale walls and structures to gain entry.

If you have a rat infestation, it’s crucial to eliminate their access to food and seal off any potential entry points. Keeping your living space clean and free of food debris, as well as sealing cracks and holes, can help deter rats from entering your home.

Rats are social and like living in groups

Rats are highly social animals that prefer to live in groups. They establish hierarchies within their colonies and have a complex social structure. This social behavior can be seen in both wild rats and pet rats.

In the wild, rats live in burrows or nests, which they build together. They communicate with each other through vocalizations, body language, and scent marking. They also engage in playful activities, grooming each other, and even sharing food.

When it comes to infestations, the presence of one rat often indicates the presence of more. Rats reproduce rapidly, with a female rat capable of producing up to 12 litters per year, each containing around 6 to 12 pups.

Therefore, if you spot a rat in your home, it’s essential to take immediate action to prevent further infestation.

Rats are territorial creatures

Rats are territorial creatures and mark their territories using urine and scent glands. They have a strong sense of smell and use it to navigate their surroundings and recognize other rats in their colony. This territorial behavior is crucial for their survival and reproduction.

When it comes to rat control, understanding their territorial nature can be helpful. By using their own scent as a deterrent, rats can be discouraged from entering certain areas. For example, if you find rat droppings or evidence of their presence in specific locations, placing repellents or traps in those areas can help prevent them from returning.

It’s important to note that while rats may leave on their own in some cases, such as when their food source is depleted, it’s generally not advisable to wait for them to leave on their own. Rat infestations can quickly escalate, leading to property damage and health risks.

Taking proactive measures to eliminate rats and prevent their return is the best course of action.

Why Rats Won’t Leave on Their Own

When it comes to rats, they are unlikely to leave your home on their own accord. Here are a few reasons why:

Your home provides ideal shelter

Rats are opportunistic creatures that seek out shelter in warm and cozy environments. Unfortunately, your home fits the bill perfectly. With its abundance of hiding spots, insulation, and comfortable nesting areas, rats see your home as a safe haven.

They are unlikely to voluntarily leave such an ideal shelter.

Rats have a remarkable ability to squeeze through even the tiniest of gaps, making it easy for them to enter your home. Once inside, they are skilled climbers and can easily access attics, basements, and wall cavities.

Their flexible bodies and sharp teeth allow them to gnaw through materials like wood and plastic, creating entry points and expanding their territory within your home.

There is a constant food source

Another reason why rats won’t leave on their own is the availability of food. Your home provides a consistent and abundant supply of sustenance for these pests. From crumbs on the kitchen floor to open food containers in the pantry, rats can easily find enough to eat within your home.

Rats are not picky eaters and can feast on a wide variety of food items. They can consume up to 30 grams of food per day, which is roughly equivalent to their body weight. With such a voracious appetite, they will continue to stay and breed as long as there is an ample food source available.

Your home is now their territory

Once rats have established themselves in your home, they mark it as their territory. They leave behind pheromone trails and scent markings, indicating to other rats that this area is already occupied. This territorial behavior makes it unlikely for rats to voluntarily leave, as they will defend their newfound territory against intruders.

Rats are social animals and live in colonies, with a dominant male leading the pack. They reproduce rapidly, with a female rat capable of giving birth to up to a dozen pups every three weeks. This means that the rat population in your home can quickly multiply, making it even more challenging for them to leave.

Solutions for Removing Rats Safely

Seal up entry points

One of the first steps in rat removal is to seal up any potential entry points in your home. Rats can squeeze through small openings, so it’s important to thoroughly inspect your property for any gaps or cracks.

Use materials like steel wool or caulk to seal these entry points and prevent rats from entering your home. Remember, rats can also climb, so be sure to check for any openings near the roof or attic.

Remove food sources

Rats are attracted to food, so it’s crucial to eliminate any potential food sources that may be attracting them to your home. Store food in airtight containers, clean up spills and crumbs immediately, and secure garbage cans with tight-fitting lids.

By removing their access to food, you are reducing the chances of rats staying or returning to your property.

Use humane traps

If you prefer a more humane approach to rat removal, consider using live traps. These traps allow you to capture the rats without harming them, giving you the option to release them in a more suitable location.

Place these traps in areas where you have noticed rat activity, using bait such as peanut butter or dried fruit to attract them. Check the traps regularly and release the rats far away from your home.

Employ natural repellents

There are several natural repellents that can help deter rats from your property. Peppermint oil, for example, has a strong scent that rats find unpleasant. Soak cotton balls in peppermint oil and place them in areas where rats are likely to be.

Additionally, ammonia and vinegar can also repel rats due to their strong odors. Just be sure to use caution when handling these substances.

Consider adopting a cat

Cats are natural hunters and can be an effective way to keep rats away from your property. Their mere presence can be enough to deter rats from entering your home. If you’re considering adopting a cat, be sure to choose one that has a reputation for being a good mouser.

However, it’s important to note that not all cats have the instinct to hunt rodents, so do your research before making a decision.

Hire a professional exterminator

If you’ve tried various methods to no avail, or if you’re dealing with a severe rat infestation, it may be time to call in the professionals. A professional exterminator has the knowledge, experience, and tools to effectively remove rats from your property.

They can assess the situation, develop a customized plan, and safely eliminate the rats. Make sure to choose a reputable exterminator with positive reviews and appropriate certifications.


While the idea of rats leaving your home on their own may seem appealing, it simply won’t happen as long as conditions remain ideal for them. The most effective way to get rats to vacate your property for good is through a combination of sealing up entry points, removing food sources, and employing humane removal methods.

With some diligence and patience, you can safely evict your unwanted rat tenants. The sooner you take action, the better. Implementing preventative measures can also help ensure rats don’t return to invade your home in the future.
