Peppermint’s strong scent can overwhelm a rat so much that they leave a peppermint-scented location because they struggle to breathe with the strong smell.

Luckily, it’s a scent humans enjoy and can make your home smell fresh.

2. Cats

Cats kill rats, and if there is a strong smell of cats, they may be declined to venture into such areas. Rats feel threatened in these areas and won’t feed or nest with a cat’s aroma.

3. Ammonia

Humans don’t enjoy smelling ammonia, but to a rat and rats and mice, ammonia smells like cat urine.

Used ground coffee won’t keep mice away, so it isn’t a natural way to keep them away from pet food. If the coffee is in the trash can or if you add coffee grounds to your compost bin, it’s the smell of rotting food that attract mice and rats rather than the coffee

What Pests Do Coffee Grounds Repel?

While they don’t repel mice and other rodents, coffee grounds can repel some insects:

  • Ants and beetles
  • Mosquitos
  • Wasps and Bees

Rats Hate Cayenne Pepper and Hot Sauce

To survive, rats rely mainly on their senses of smell, taste, and touch.

They avoid something that doesn’t smell or taste right as it triggers their sense of danger, hence why the smell or sight of a cat is enough to get rid of them.

Capsaicin is found in spicy fragrances like hot sauce and chili powder. Pepper plants use this as a protective mechanism against being eaten, but humans overlook this s they taste nice.

This spicy taste and smell repel rats, repel mice, and other creatures. The hot capsaicin causes discomfort and burning in their tongues and taste receptors.

You can make an effective spray to keep rats away:

  • 4 cups water
  • 2 oz. of hot sauce
  • 1 tsp of dish soap

In a spray bottle, combine all the ingredients. To make the mixture stick to the surface, dish soap is applied.

Spray in areas where rats are a problem, like attic windows, loose roofing tiles, and even close-to-the-roof branches, which offer entry points for roof rats.

You might also use chili powder or Cayenne Pepper Flakes. Because crushed red pepper is a blend of cayenne and hot peppers, it usually works.

This substance should be spread around entrances or areas where you think rats are getting in.

You can use garlic in the same way because of the allicin, which gives garlic its characteristic odor. Like capsaicin in chili peppers, allicin is a plant’s defense mechanism and keeps animals from eating it.

Onions are comparable to garlic in their strong and unique odor. This is owing to the sulfur-containing chemicals in their compounds.

These sulfuric chemicals, like allicin, have a strong odor that will repel mice and make rats think twice.

Repel Rats with Peppermint

Whether it’s oils or the plant, minty scents keep pests away.

Repellents for Tomcats use peppermint oil, a tremendous ready-to-use commercial repellent.

It’s supposed to last 30 days, but you’ll need a further application after rain.

In addition, planting peppermint plants around your home and yard could be an alternative. This is a long game, but it pays offs.

Peppermint is a perennial plant that takes one planting and will keep coming back every spring. Plant peppermint near your garden’s most sensitive veggies, such as carrots, potatoes, squash, and pumpkin, which are all rodent favorites.

Another alternative is to use essential oils. In a spray bottle, combine 10-15 drops of peppermint oil with 1 cup of water. Wintergreen oil and spearmint oil have comparable work.

Another method for repelling rats is to soak cotton balls in peppermint oil and strategically place cotton balls in areas where rats have nested or are likely to travel.

If you don’t have peppermint oil and need to act quickly, grab some peppermint toothpaste and apply it on a cloth, then place the cloths where the rats are. (Read Average Coffee Cup Size Guide)

Cloves to keep rats away

Use Cloves to Deter Rats

Cloves and clove oil are another practical approach to keep rats away. Unfortunately, cloves are hated by rats because they smell not only clean but also smell spicy.

Placing whole cloves in vents around the house and other openings you discover within your home’s walls will also help keep the strong scents in areas rats would go.

It can be time-consuming, yet once you keep up with it, it is as effective. If you’re using clove oil, soaking cotton balls in it and putting them around outdoor and interior settings could help, and it smells better than ammonia.
