What Smell Will Keep Rats Away?

Mice or rats can cause a significant amount of trouble. They're not just unclean but also dangerous and destructive.

As unwelcome as any visitor is, rats are more unwelcome in private residences. They scurry around your home at night, making noises in the cellar or attic, and seeing one can make you feel disgusted and make you wonder, "Why me?!" Fortunately, many methods are available to prevent rats from entering your home.

Keep reading to discover which aromas will drive rodents from your house and garden! In addition, we'll discuss other methods to prevent rodents in the house.

What's So Bad About Rats Anyway?

Do rats pose such a significant health risk? If you've ever dealt with a rat infestation, you probably already know the answer.

The presence of rats in the home might result in numerous issues. They cause damage by chewing on various items, including wood, furniture, siding, and electrical wiring. They will gladly eat from your garden orchard or vegetable patch because they enjoy the taste of fruits, nuts, and vegetables.

When rats find their way inside a building, they often defecate all over the place, leading to hygiene problems. Similarly, rats will not avoid trash and can go from snuffing around in the trash to racing across your kitchen counter (where food is prepared) in seconds.

You can also construct nests near switchgear, woodpiles, and under sheds. Subterranean rat infestations can cause serious structural damage to your home because the rodents tunnel under the foundation and construct elaborate networks of tunnels.

Overall, it's not a good pet to have at home.

The Scents That Rats Hate

You may often find two different kinds of rats in the United States. Specifically, Norway and roof rats. Norway rats are sometimes known as brown rats, common rats, and even sewer rats. Many species belonging to the same genus and species. It's common knowledge that roof rats are also referred to as black, ship, and house rats. All the same species once again.

It is significant since the two species of rat frequent completely different home and yard areas.

The Norway rat is a good example; it prefers the ground floor and may often be found in attics and garages. On the other side, roof rats favour higher elevations, such as roofs, trees, and buildings.

Roof rats, on the other hand, are unlikely to be lounging in your garage and, therefore, can't be deterred by spreading chilli powder there.

Clover Plants Can Repel Rats

Yes, today is your fortunate day! When planted in a garden, clover can be used to deter rodents. You've probably heard of three-leaf clovers and four-leaf clovers. Of course, all those green things are clover! However, the tiny white flower that's often found next to these supposed lucky clovers is the focus here.

The pungent smell of a clover plant may be one reason it is so effective at keeping rodents at bay. But, unfortunately, springtime is when these seemingly useless plants sprout up all over your yard; their usefulness is often overlooked.

You can pluck the blossoms from your yard to ward off rodents. However, it is time-consuming, as the flowers should be changed every three to five days to maintain a pleasant aroma.

Another negative is that once spring is finished, you won't have any more clover plants to use.

Soaking the plants in water is another method. The water will absorb the flowers' fragrance and take on a fresh scent once you spray it. 

Picking the flowers may release a greater repelling aroma, but this method may last a little longer and provide better coverage.

Mice and rats abhor the fiery flavours of hot sauce and cayenne pepper.

Who doesn't enjoy a dish with a little heat? Hot and sour soup or tangy buffalo wings. Yum! If rats, though? It's not a sensation that's shared.

Rats get by mostly on their sense of smell but also use taste and touch. So those with heightened threat perception avoid anything that doesn't pass the smell and taste tests.

Capsaicin is the chemical responsible for spices like chilli powder and hot sauce spiciness. So what gives spicy peppers their heat? Pepper plants evolved this to protect themselves from being eaten, yet we humans still love to snack on them.

However, this plant's intense aroma and flavour are off-putting to rats and other mammals. They report that the hot capsaicin burns their mouths and makes their taste buds uncomfortable.

Combine everything in a glass spray bottle. Adding dish soap helps the mixture adhere to the container. Use the spray in locations where rats are a problem.

Chimneys, attic windows, displaced roof tiles, and even nearby tree branches are common entry points for these rodents. Unfortunately, there are no places here that you can't spray.

Norway rats often access a home through holes in drain pipes, cellar drains, sewage drains, and even shower drains. Therefore, you should also spray any openings, such as basement windows.

Make sure you're using the appropriate peppers to repel those rats, as regular red bell peppers do not contain capsaicin.

Garlic's anti-vampire properties are not limited to that. It's effective against various rodents, scavengers, and grazers.

The pungent odour of garlic is its primary repelling effect. Have you ever eaten something garlicky and felt you couldn't get the flavour out of your mouth?

Allicin, if you will. Exactly what gives garlic its pungent aroma is this chemical. Like capsaicin in chilli peppers deters animals from eating the plant, allicin is a defence mechanism established by garlic to deter grazing animals. Yet, we humans again disregard that advice and season everything with garlic. Where have we gone wrong?!

As with garlic, onions give off a pungent odour easily recognisable. It's because they contain chemicals rich in sulphur. This powerful odour is similar to allicin, and these sulfuric chemicals will likely deter rats.

It's safe to say that garlic's many potential applications have contributed to its widespread popularity. Using whole cloves to fortify weak locations is a viable strategy, but it's pricey, and the cloves will go bad before long.

Rats Hate Ammonia

Potent odours play a significant role.

The odour of ammonia is quite pungent and chemical. Ammonium hydroxide is the version used for domestic use. Many households rely on it to scrub hard-to-reach places like showers, tiles, and sinks.

You can also use household ammonia to deter rodents. The most straightforward method of using ammonium hydroxide to repel rats involves soaking rags or cotton balls in the chemical and then placing them in open bags or containers.

Put the containers or bags where you want to protect them from rodents. Things like rat poop can signal that rats are there, so keep an eye on the attic, the windowsills, the basement drainpipes, and any other places you suspect they might be.

Used Coffee Grounds Deter Rats

To what end did you keep those used coffee grounds? Yes, you do now! But, instead of throwing them away, use them to keep unwanted visitors out of your home.

Coffee grounds, particularly those steeped in hot water, have a bitter taste and potent aroma. Rats will be scared away from your home by this double-whammy deterrent.

Wet coffee grounds are spongy and undesirable on surfaces. It would help if you instead treated ammonia in the same way. Spread your used coffee grinds around your heaters in an open plastic bag or container.

Use them to keep rats out of your garden by tossing them in. In addition, Composting coffee grounds can help fertilise your garden and deter rodents and grazers like deer from eating your plants.

Peppermint, Wintergreen & Spearmint Will Repel Rats

Do you agree that these would make delicious gum flavours? Oils and plants with a minty scent have long been used to deter pests.

Tomcat Defeating Devices Rodent Repellant, a ready-to-use commercial repellent with peppermint oil as one of its key constituents, is an effective choice. However, the manufacturer recommends applying it more frequently after heavy rain or increased rat activity, as the 30-day shelf life is only an estimate.

Planting peppermint plants in and around your house and yard is yet another option. Playing the long game here will eventually pay off. In contrast to annual plants, peppermint will return year after year with just a single planting.

You can use peppermint toothpaste if you need a quick solution but don't have any peppermint oil. Instead, rub some onto a piece of fabric and hang it near the areas where rats are a problem.

Cloves Deter Rats

Cloves and clove oil are another effective means of preventing rodent infestation. Cloves have a dual-purpose odour and taste that drives rats crazy. Cloves smell clean and also have a strong, pungent aroma.

When wrapped in a cloth and placed in rodent-infested locations, whole cloves can effectively drive the pests away. Whole cloves placed in vents and other holes inside the home's walls can also be effective.

Clove oil can work wonders if you soak cotton balls and place them strategically throughout your home and yard.

Evidence suggests eucalyptus oil can deter rats.

Myrtles, which include these towering trees, is a diverse and interesting group.

If the rat infestation is contained, you can use the cat-scented item in a specific area. Break up the blanket or bed into smaller pieces and disperse them, pushing them into cracks or placing them near drain pipes if you foresee a widespread problem.

Not a cat owner? Ask your friends and neighbours for unused blankets or toys for your cat. Of course, people might give you a funny look, but if it helps, then it must be doing something right!

Use Cat Fur To Repel Rats

According to the research, you can also use cat fur to deter rats when placed in high-traffic locations.

Gather some cat hair that has been shed off your pet and sprinkle it around rat-prone areas and entryways to deter indoor and outdoor rats effectively. It works whether or not you own a cat.

The mere presence of the cat's scent is enough to deter the rat from venturing into such areas, even if it never actually sees the animal.

As long as your cat doesn't shed excessively, brushing it and reusing the hair that comes off is an excellent solution.

White Vinegar As A Rat Repellent

There's no denying that white vinegar has a pungent odour. Strong and unpleasant, with a spicy undertone and a sharp finish. Regardless of my aversion to the scent of white vinegar, the fact remains that rats abhor it.

If a rat were to lick at a drop of white vinegar, it would taste awful and burn its digestive tract. 

A rat will be completely taken aback by the pungent smell of white vinegar, especially if it wasn't one of the odours they detected when they first visited the site.

Adding white vinegar to a rat's surroundings will alert the rodents to a new and potentially dangerous element.

Citronella Oil Repels Rats

The citronella repels rats. It's ironic, really, since while the stench would be overwhelming to a rat, it would seem really fresh to us. So we shouldn't be shocked that rats avoid citronella because it smells so clean and fresh.

A wide variety of animals universally revile the aroma of citronella. The overwhelming potency of the odour will render the rat nearly helpless in its attempts to forage for food and defend itself against predators.

According to a study published in Applied Biological Research, citronella oil has been shown to reduce rat food consumption. Furthermore, according to the study, the efficiency of the repellent was also observed to rise at a concentration of 10% citronella oil.

Scent plays a significant role in the rat's daily life because rats are very scent-driven. Since rats avoid situations where they feel threatened, citronella will likely be avoided.

You can try growing citronella, but you'll need a lot of it to see any results. To use citronella oil as a rodent deterrent, dilute your prefered 100% essential oil concentration down to around 10% strength.

You can then wet some rags or cotton balls (or use a spray) with your mixture and distribute them to the locations you want to protect from rats.

Conclusion

Rats in the house can cause a lot of problems. Rats are destructive pests that gnaw on structures, food, and even wires and cables. Due to the tunnelling activities of rodents, subterranean rat infestations can result in extensive damage to a home's underlying structure. Clover can be used to keep rats at bay when grown in a garden. It's possible that the potent effectiveness of clover is at least partially attributable to its distinctive odour.

However, roof rats probably aren't hanging out in your garage and won't be scared away by a little bit of chilli powder. The strong smell of garlic is its most effective deterrent. Allicin, like capsaicin in chilli peppers, is a defence mechanism garlic developed to ward off herbivores. In addition to protecting your plants from rodents and predators, composting coffee grounds can help fertilise your yard. Cloves and clove oil are also useful for warding off rodents.

White vinegar has a very strong acidity that can burn a rat's stomach if it licks even a drop. When white vinegar is introduced into a rat's environment, the rats become aware of a novel and potentially harmful substance. There is evidence that citronella oil can decrease rat appetite. Rats are deterred from human settlements by the presence of larger predators, such as hawks, eagles, and dogs, and by the stark size contrast between the two.
