Best Natural Repellents to Kill Rats in the House

We don’t always need poisons, i.e., rodenticides which might be detrimental to us as well as for our pets if inhaled. Therefore, we can follow straightforward and natural home remedies to get rid of rats. Home remedies are more preferred because they are effective as well as nontoxic.

Peppermint Green fresh mint on the wooden table

Rats have an acute sense of smell. We, humans, find the fragrance of peppermint as refreshing and pleasant while it’s very offensive for rats.

REQUIREMENTS: Few cotton balls and peppermint oil.

DIRECTIONS: Add 25-30 drops of peppermint essential oil to every cotton ball and place it surrounding your home. Keep replacing it when you feel the smell is diminishing off. The peppermint oil kills the rats as soon as they feel it which directly affects their lungs, shrink them and kill the rats off. If you are not willing to put peppermint essential oils, you can go for minty toothpaste or peppermint leaves.

Moth Balls

Moth balls can repel both rats and mice. They are poisonous to both humans and mice.

DIRECTIONS: Place moth balls in deserted areas like an attic, backyards or basement. Touch them with covered hands and try to be careful. They are readily available, and they are simple to use.

But keep in mind that it takes a lot of moth balls to kill a rat. In fact, moth balls may not actually kill rats at all. The moth balls contain a substance called naphthalene, and while it’s pungent, it takes a lot of the substance to be effective.

When inhaled or consumed, it can cause blood cells to lose their ability to carry oxygen. While in theory this may be able to kill a rat, moth balls have just small amounts of naphthalene.

If you want to use moth balls as a rat deterrent, make sure that you use a very generous amount of moth balls – more than you would with a mouse.


Ammonia is a super cleaning agent, but it acts as an excellent repelling agent to the rodents.

REQUIREMENTS: 2 -2 1/2cups of ammonia, 100- 200 ml of water and 2 -3 spoons full of detergent.

DIRECTIONS: Mix all the above substances in a bowl and place the bowl near those locations where rats are frequently found. Ammonia has a pungent smell which rats do not like.

If you don’t want to leave a bowl of ammonia out, you can choose to do a few things:

Soak a cloth in ammonia and place it in a can

Soak cotton balls and place them in key areas where you’ve seen rats

Ammonia actually mimics the smell of other animal urine. Foxes and cats, both known to keep rats away, have a similar smelling urine to ammonia. If you want a natural rat repellent, you can always use used cat litter, but it’s usually one of the least desirable ways to get rid of rats.

The texture of owls feather

Owls Feather

There are few natural predators of rats and mice which include owls and snakes. However, we can’t bring them home so we can act smart and put some owl feathers near the holes of rats. These feathers are inexpensive and simple to use. They act as a wonderful repellent to mice.

Black Pepper

Pepper produces a very sharp smell. This smell is very offensive for the mice and rats. It acts as an excellent repellent against them. As soon as the rats inhale the aroma of pepper, their lungs react, and they are dead.

DIRECTIONS: Sprinkle a small amount of black pepper around the residing places of rats.

Bay leaf

Bay leaf has an aromatic smell which commonly attracts the rats. They try to feed upon the bay leafs and end up choking themselves. Bay Leafs possess secondary metabolites which are found to be toxic to the mice.

DIRECTIONS: Put some bay leafs around the tiny holes and corners of your house.

Onions Red onion isolated on white background

Onions have a pungent smell as well. This smell is not tolerable for rats or mice. As soon as they smell onions, they try to run away from such places. That is one of the most efficient remedies.

DIRECTIONS: Cut onion slices and place it around areas inhabited by rats or mice.  Try to replace the onions every day as they rot with time.

Human Traps

Human traps are the easiest and the most efficient methods for people who would not like to kill the rats. These traps are easy to use and available easily in the market. They comprise of two types i.e. sticky trap and snap trap.

Snap traps entail spring which activates as soon as the mouse reaches for the bait. While sticky traps are considered to be inhuman as the rats get stuck when they try to escape, they eventually die due to starvation or dehydration. Electronic mouse traps are also available in the market.

DIRECTIONS: Put a fresh bait, cheese or peanut butter inside the trap. As soon as the rats reach to eat the food, they get stuck in the trap; now you can take the trap far away from home and release the mouse.

Dried snake/Cat litter

You can visit a pet store or zoo and buy some litter of dried snake. Put it in the holes of the house where rats are seen. For the same purpose, we can also use cat’s litter which is suggested by farmers because cats are considered as the natural predators of rats.

If you don’t want to place litter around your home, you can choose to buy one of the most deadliest predators against a rat as your new pet: a cat.

Human Hair

You can place some human hair inside the rat holes to frighten them as they may eventually swallow the hair the moment they see them.

Cow Dung Cow pooping cartoon

Cow manure is a natural rat killer when they eat this litter; their stomach gets upset. After some time they begin to vomit and eventually it leads to the death.

DIRECTIONS: Place some amount of cow dung in closed areas like your basement, attic or parking lots, the hole where rats reside. They’ll be dead instantly as soon as they eat it because of the rupture of their gastrointestinal system.



DIRECTIONS: Switch on the audio box near the holes of rats. These sharp sounds are not tolerable by the rats. Their ears start bleeding, and they die after some time.

Baby Powder

The smell of the baby powder acts as a deterrent to rats and mice. It’s not considered as an efficient method. However, baby powder helps in the intoxication of rats leading them to death.

DIRECTIONS: You need to sprinkle a small amount of powder near the rat holes.

Steel Wool

Try patching the holes in the wall with steel wool. It is a solid material, and mice find it difficult to bite this material. The steel wool acts as a barrier and prevents the rats from crossing it.
