Peppermint Oil for Roaches: How to use in Your Home?

Peppermint oil is used as a natural repellent for roaches. It is primarily composed of menthol and menthone. It also contains smaller amounts of other compounds like limonene, pulegone, caryophyllene, and pinene. Menthone is responsible for the minty aroma of peppermint oil. The strong smell of peppermint can deter roaches and other pests from entering your home. There are different methods to use it in house. Dilute a few drops of the oil in water and spray it in areas where roaches are commonly found, such as in kitchen cabinets or near baseboards. You can also place peppermint oil on cotton balls and place them in areas where roaches are a problem. It cannot kill roaches and is used only to prevent roaches from entering the home.

Composition of Peppermint oil

Peppermint oil is a versatile and popular essential oil made up of a complex blend of compounds, including menthol and menthone, which make up around 50-70% of the oil, giving it a cooling and minty aroma. Limonene and pinene contribute to its refreshing scent, while caryophyllene adds a spicy note. Pulegone adds a slightly sweet, woody aroma. These compounds work together to create the unique properties of peppermint oil that make it useful for a wide range of applications, such as aromatherapy, as a natural remedy for headaches, as a natural insect repellent, in cleaning products, and personal care items such as toothpaste, shampoo, and soap.

How Does Peppermint Oil Repel Roaches?

Peppermint oil repels roaches through its strong minty aroma. Roaches have a highly developed sense of smell, and the strong scent of peppermint can be overwhelming for them. The menthol in peppermint oil can also have a repellent effect on roaches. When sprayed or diffused in an area, the scent of peppermint oil can cause confusion and disorientation in roaches. It makes it difficult for roaches to navigate and find food and shelter.

Does Peppermint Oil Kill Roaches?

Peppermint oil is a natural repellent that can keep roaches away due to its strong minty aroma, but it will not kill them. It can be used with other methods, such as proper sanitation, sealing off entry points, and using bait traps to get rid of roaches. Peppermint oil alone might not be enough to eliminate a roach infestation, and it’s best used as a preventive measure.

How to use peppermint oil to repel roaches?

There are several ways to use peppermint oil to repel roaches in your home.

How to use peppermint oil to repel roaches


Mix a few drops of peppermint oil with water in a spray bottle. Spray the solution in areas where you have seen roaches or where they are likely to enter, such as around windows, doors, and baseboards. You can also spray it on areas where roaches hide, like under appliances and inside cabinets. This will create a barrier that will keep the roaches away.


Use a diffuser to disperse peppermint oil into the air. This can be especially effective in larger areas such as basements or attics. It will help to keep the entire area free of roaches and also give your home a fresh and clean smell.

Cotton balls

Soak cotton balls in peppermint oil and place them in areas where roaches can be present, such as in cabinets, under sinks, and behind appliances. The cotton balls will release the aroma of peppermint oil over time, keeping the roaches away.

Bait stations

Mix peppermint oil with a food source, such as sugar or flour to create a bait station for roaches. Place the bait in the cockroach-infested area.
