When you have one rat left, your main priorities are providing extra human attention and finding it a companion, as rats are highly social and lonely rats can become depressed; look to rescues or breeders for a compatible friend, consider fostering temporarily, or, if it's very old/sick, maximize its comfort with toys and playtime while preparing for grief, notes About Pet Rats, Lafeber Company, and Reddit users.
A single rat is often happy, whenever you are playing with it. But when you are asleep, or out at work or school, or simply going shopping, the single rat can get bored and lonely. It has nothing to do whenever you are not around.
Although rats may not have the intellectual ability to rationalize such a loss, it is clear that they recognize their companion is gone and they can show many of the same physical manifestations that we feel. A grieving rat may eat less, appear depressed, or become restless.
- Turn off lights and avoid sudden movements if the rat is visible; rats usually try to escape, not attack. - Keep pets and children away from the area. - Do not attempt to pick up, hit, or trap a rat with bare hands. Rats can bite if frightened and may carry fleas or disease.
That single rat is often a scout, or if it's a female, she could already be pregnant and ready to start a nest. Rats are nocturnal and avoid people. Seeing one in daylight suggests the population is so large or food is so scarce that they are forced to search for food during the day.
Both ammonia and vinegar have sharp, acrid odors that rats detest. Ammonia mimics the smell of predator urine, creating a sense of danger, and vinegar's acidic smell irritates their sensitive noses.
Wild rats are not used to human contact and will bite when handled or when people attempt to feed them by hand. The nocturnal creatures have also been known to bite sleeping people, particularly children and infants, on exposed body parts such as fingers, hands, toes and the face when foraging for food.
Rats are attracted to houses primarily by easy access to food, water, and shelter, especially warm, cluttered, and dark spaces like attics, basements, and wall cavities, with common attractants including unsecured garbage, pet food, birdseed, fallen fruit, leaking pipes, and clutter like cardboard boxes or woodpiles that provide nesting sites. Sealing entry points, removing food/water sources, and reducing clutter are key prevention steps.
The professional consensus is that if you've spotted one rat, you likely have many more. In a warm and food-rich environment, such as your home, a single breeding pair of rats can quickly turn into a dozen within a few months.
Rats may leave if food and shelter are eliminated, but active measures are usually necessary for complete removal.
There is solid research that rats do recognize people. For example, a study showed that laboratory rats preferred familiar human handlers over strangers even after just a few exposures.
Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise. Garbage is an excellent food source for rodents. Store garbage and rubbish in rodent-proof containers.
Rats don't like to live alone. They tend to suffer from loneliness and depression. If one of their group is sick they will take care of them. When a rat plays they omit a happy laughter sort of sound.
It could be because they no longer enjoy where they are living. It could also be because they have found a better source of food. If you haven't spotted rats in a while, there's a good change they might actually be gone. But how do you know if this is actually true.
The fastest way to get rid of rats involves an integrated approach: immediately set snap traps with strong bait (peanut butter/oats) perpendicular to walls for quick kills, block all entry points with steel wool/caulk, and remove food/water sources by cleaning thoroughly and storing food in sealed containers to starve them out, preventing recurrence. While baits work, traps are faster for immediate control and avoid the odor of hidden poisoned rats, but require careful handling.
Regardless of if you're dealing with a vegetarian or an omnivore, however, food with strong smells — nuts, fish, or moldy cheese — are best at luring rats into traps. Check out our baiting guides for brown and black rats.
It's possible to repel rats using essential oils such as peppermint oil and other smells that they naturally don't like. Using peppermint oil is one of the easiest ways to keep rats away from your home as long as you aren't giving them an easy food source.

Sleeping with the lights on will not effectively keep rats away.
The Rat's Worst Fear: Instincts and Survival
Rats are equipped with large teeth and administer painful bites when threatened. Healthy rats typically avoid people and prefer to be active when buildings are quiet. However, when cornered, they will lunge and bite to defend themselves.
Camphor/Mothballs
These contain naphthalene, which release a scent that is disliked by rats.
Mothballs
The strong chemical smell they give off also makes them effective repellent for rats, but it is also toxic to them. This is because mothballs contain active ingredients like paradichlorobenzene or naphthalene, which are fumigants toxic to both animals and people.
The strong, acidic aroma of vinegar is another effective rat deterrent. White vinegar or apple cider vinegar diluted with water can be sprayed or wiped around potential entry points. Damp can exacerbate odours, and vinegar can help to neutralise existing rat smells.
