Does Cinnamon Oil Kill Bed Bugs

Quick Answer:

No, cinnamon oil is not a proven solution to kill bed bugs. Scientific evidence supporting its effectiveness is limited.

Bed bugs are resilient, and eradication usually requires professional pest control methods. While cinnamon oil might have a repellent effect, it's unlikely to eliminate an infestation.

Cinnamon oil is a natural extract from cinnamon, the tasty spice we use in cooking. While it has a pleasant smell and is used in various products, it's not the best for killing bed bugs.

Cinnamon oil might not be strong enough to eliminate these pests. Bed bugs are tough and can survive or even become resistant to cinnamon oil.

People often prefer other methods or stronger insecticides specifically designed to tackle bed bug infestations for a more effective solution. So, while cinnamon oil has its uses, it might not be the ideal choice for battling bed bugs.

Do Bed Bugs Dislike Cinnamon?


Yes, bed bugs have an aversion to cinnamon. Cinnamon contains compounds that act as natural repellents against these pests, making it a popular home remedy for bed bug control.


To use cinnamon to deter bed bugs, you can sprinkle ground cinnamon around the areas where bed bugs are likely to hide or travel, such as near beds, baseboards, and furniture.

Additionally, you can create a spray by mixing cinnamon essential oil with water and then spraying it in affected areas.

Cinnamon oil is often not recommended for bed bug control due to its limited efficacy and potential drawbacks. While cinnamon oil is known for its pleasant aroma and some antimicrobial properties, it lacks sufficient evidence to support its effectiveness against bed bugs.

Bed bugs are resilient pests that require robust and proven eradication methods. Cinnamon oil may have a repellent effect on bed bugs, but it is unlikely to eliminate an infestation.

Moreover, the concentration required to impact bed bugs significantly may be impractical and lead to skin irritation or other adverse reactions in humans.

Additionally, cinnamon oil does not provide a long-lasting residual effect, meaning it won't continue to control bed bugs over an extended period. This is crucial in bed bug management, as these insects are notorious for their ability to hide and reemerge.

Associated Risks of Using Cinnamon Oil for Bed Bugs:

Limited Efficacy

Cinnamon oil may not effectively eliminate bed bug infestations due to its repellent nature rather than eradication.

Incomplete Eradication

Bed bugs are resilient, and relying solely on cinnamon oil may leave behind surviving bugs, leading to persistent infestations.

Practicality Challenges

The concentration of cinnamon oil required for significant impact can be impractical, potentially causing skin irritation or allergic reactions in humans.

Short-Term Effectiveness

Cinnamon oil lacks a lasting residual effect, which may not provide sustained control over time, allowing bed bugs to reemerge.

Risk of Skin Irritation

Direct contact with concentrated cinnamon oil can irritate skin, making it an unsuitable solution for sensitive skin.

No Professional Validation

Unlike established bed bug control methods, cinnamon oil lacks comprehensive validation from pest control professionals, making its effectiveness questionable.

Prolonged Infestations

Relying solely on cinnamon oil may result in prolonged infestations, as it may not address the comprehensive needs of bed bug eradication.

Best Methods To Kill Bed Bugs

Harris Bed Bug Powder:

Harris bed bug powder is a widely recognized and trusted solution for combating bed bugs. The key ingredient in this product is diatomaceous earth (DE), a naturally occurring substance derived from fossilized algae. DE is known for its remarkable effectiveness against bed bugs and other crawling insects.

Here's how Harris bed bug powder works:

  • Dehydration: DE is a desiccant that dries out its target by absorbing moisture from its exoskeletons. When bed bugs come into contact with the powder, it clings to their bodies, causing them to dehydrate and ultimately die.
  • Long-Lasting: Once applied, Harris bed bug powder remains active for an extended period. It continues to kill bed bugs that come into contact with it, providing ongoing protection against infestations.
  • Safe for Humans and Pets: Harris bed bug powder is non-toxic to humans and pets, making it a safe option for home use. However, following the application instructions carefully is essential to ensure its effectiveness.

To use Harris bed bug powder, simply apply a thin layer in areas where bed bugs are suspected to hide, such as cracks, crevices, and behind furniture. Regularly reapply as needed to maintain its efficacy.

Natural Remedies

If you prefer a more natural approach to bed bug control, several remedies may help deter these pests. Some of these remedies include:

  • Essential Oils: Certain essential oils, such as lavender, tea tree, and peppermint, have insect-repelling properties. Mixing a few drops of these oils with water in a spray bottle and applying it to areas where bed bugs hide can help discourage them.
  • Vacuuming: Regular and thorough home vacuuming can help reduce the bed bug population by removing eggs, nymphs, and adults. Immediately empty the vacuum bag or canister and dispose of the contents outdoors to prevent re-infestation.
  • Hot Washing and Drying: Washing bedding, clothing, and curtains in hot water (at least 120°F or 49°C) followed by a hot drying cycle can effectively kill bed bugs and their eggs.
  • Steam Cleaning: Using a steam cleaner with a high-temperature setting can penetrate deep into cracks and crevices, killing bed bugs and their eggs on contact.

While these natural remedies may help manage a small infestation or prevent one from occurring, Harris bed bug powder may be less effective than they are for larger infestations.
