Top 10 Scents That Keep Bed Bugs Away


Bed bugs — those tiny, elusive invaders that creep into your bedsheets and turn your peaceful sleep into a waking nightmare. While they're not known to spread diseases, their bites are itchy, irritating, and leave behind anxiety and sleepless nights.

In Mississauga, Ontario, where urban life and apartment living are common, bed bug infestations can spread quickly from one unit to another. The good news? While professional extermination is always the most effective solution, certain natural scents can help repel bed bugs before they become a serious problem.

At Speedy Pest Control, we believe in combining professional pest management with practical, preventative home tips. So let’s dive into the top 10 scents that keep bed bugs away — and how you can use them to protect your space.

1. Lavender

Lavender isn’t just relaxing — it’s also a powerful bed bug repellent.

Why it works: The strong floral scent of lavender oil is overwhelming to bed bugs. It interferes with their sensory systems and drives them away from treated areas.

How to use:
  • Add a few drops of lavender essential oil to a spray bottle with water and spritz it on mattresses, bed frames, and baseboards.
  • Use lavender-scented laundry detergents or sachets in drawers.

2. Peppermint

This refreshing and sharp-smelling oil is another natural enemy of bed bugs.

Why it works: Peppermint contains menthol, which is toxic to many insects. Its strong aroma also disrupts the pests’ ability to communicate and locate hosts.

How to use:
  • Mix 10-15 drops of peppermint oil with water and spray around the bed, furniture, and cracks.
  • Place peppermint oil-soaked cotton balls near suspected hiding areas.

3. Tea Tree Oil

Common in skin care, tea tree oil is also a natural insecticide.

Why it works: Its antimicrobial and insecticidal properties make tea tree oil effective at repelling — and even killing — bed bugs on contact.

How to use:
  • Add 20 drops to a spray bottle with water and use it on beds, couches, and carpet edges.
  • Clean floors with tea tree oil-infused water for added effect.

4. Lemongrass

This citrusy scent does more than uplift your mood — it’s highly irritating to bed bugs.

Why it works: Lemongrass increases the acidity of the environment, which bed bugs hate. It also acts as a deterrent due to its potent fragrance.

How to use:
  • Use lemongrass essential oil in diffusers.
  • Spray diluted lemongrass oil around sleeping areas, baseboards, and window sills.

5. Eucalyptus

Eucalyptus oil has a clean, medicinal scent and is widely used for respiratory relief — and for bug control!

Why it works: Its intense smell masks carbon dioxide emissions that bed bugs use to locate their hosts. It also has antibacterial properties.

How to use:
  • Mix eucalyptus oil with witch hazel and water and spray it around the home.
  • Use eucalyptus-based cleaners for daily household maintenance.

6. Cinnamon

This kitchen favorite doesn’t just belong in your baked goods.

Why it works: The pungent smell of cinnamon disrupts the pheromone trails that bed bugs use for navigation.

How to use:
  • Place cinnamon sticks near your bed and windows.
  • Sprinkle cinnamon powder in drawer corners or under mattresses.

7. Clove

Clove oil contains eugenol, a natural insect repellent that is highly effective.

Why it works: Its acidic pH and sharp scent act as a powerful deterrent against bed bugs.

How to use:
  • Use clove oil in a diffuser or homemade room spray.
  • Add it to vinegar solutions for double the pest-fighting power.

8. Thyme

This herbal remedy works double duty as a cooking spice and bug repellent.

Why it works: Thyme has insecticidal compounds that make it intolerable for pests, including bed bugs.

How to use:
  • Burn thyme bundles (safely) in infested rooms or closets.
  • Use thyme essential oil mixed with olive oil as a surface treatment.

9. Citronella

Often used in mosquito repellents, citronella is also effective against crawling pests.

Why it works: Its strong lemony aroma is unbearable to bed bugs, who prefer dark, odorless hiding places.

How to use:
  • Use citronella candles in the bedroom.
  • Spray diluted citronella oil around beds and baseboards.

10. Orange Oil (D-Limonene)

Citrus-scented oils are growing in popularity as natural pest deterrents.

Why it works: D-Limonene, found in orange peels, breaks down the waxy coating of insects and acts as a powerful repellent.

How to use:
  • Add a few drops to your floor cleaner.
  • Use orange oil sprays on mattresses and bedding (check for staining first!).

Important Reminder: Scents Are Preventative, Not a Cure

While all of the above scents can deter bed bugs, they won’t eliminate an active infestation. Bed bugs are incredibly resilient and can hide in:

  • Wall crevices
  • Electrical outlets
  • Mattress seams
  • Behind baseboards

If you’ve seen bites, blood spots, or bed bug shells — it’s time to call a professional.
