Will Peppermint Oil Get Rid Of Bed Bugs: Bed bugs are one of the most stubborn pests that can invade your home. Small, reddish-brown insects that feed on human blood, they tend to hide in mattresses, cracks, and furniture crevices, coming out at night to bite. Because of their ability to reproduce quickly and stay hidden, getting rid of them requires a strategic approach. One common suggestion floating around the internet is the use of peppermint oil. But does it actually work?
Let’s explore whether peppermint oil is truly effective for dealing with bed bugs and how it compares with other natural options like cedarwood oil.
The Bed Bug Problem
Bed bugs are parasitic insects that are extremely difficult to detect in the early stages. They hide well, can survive for weeks without feeding, and lay hundreds of eggs over their lifetime.
Common signs of bed bug infestation include:
-
Small rust-colored stains on sheets or pillowcases
-
Dark spots (bug excrement) in seams or crevices
-
Musty odor coming from their hiding places
-
Itchy red bites, usually in clusters or a straight line
Because of their flat bodies and resistance to many chemical treatments, people often look for natural and safer solutions.
Why Do People Try Essential Oils?
Essential oils are popular in the DIY pest control community for being plant-based, easy to access, and typically safe around kids and pets. People use them for everything from insect repellent to room fresheners.
Popular essential oils believed to repel insects:
-
Peppermint oil – Menthol smell believed to deter bugs
-
Tea tree oil – Claimed to have insecticidal and antifungal properties
-
Lavender oil – Often used to create a soothing environment
-
Cedarwood oil – Known for interfering with insect pheromones
Among these, peppermint oil is frequently cited as a natural bed bug deterrent.

What Science Says About Peppermint Oil and Bed Bugs
While peppermint oil is refreshing and has known benefits like easing headaches and repelling ants or spiders, there is little conclusive evidence proving its effectiveness against bed bugs.
Unlike fleas or mosquitoes, bed bugs rely more on heat and carbon dioxide than smell when locating hosts. This makes peppermint oil less reliable as a repellent.
What peppermint oil might do:
-
Repel bed bugs temporarily if applied in high concentrations
-
Make treated areas smell unpleasant to bugs
-
Cause mild disorientation
What it does not do:
-
Kill bed bugs or their eggs
-
Interrupt their life cycle
-
Penetrate hiding spots effectively
Common DIY Uses of Peppermint Oil Against Bed Bugs
People who try peppermint oil often use it in various DIY sprays or applications, hoping for a natural fix. However, results are usually short-lived or cosmetic.
Popular methods include:
-
Spray mixture: A few drops of peppermint oil in water with a bit of alcohol, sprayed on beds, furniture, and baseboards
-
Cotton ball technique: Soaked cotton balls placed in corners, under mattresses, or inside closets
-
Oil diffuser: Dispersing the scent across a room
While these might make the environment temporarily less inviting for bugs, they are not enough to stop an active infestation.
Why Peppermint Oil Isn’t Enough on Its Own
Even if you notice fewer bites after spraying peppermint oil, the bugs aren’t gone just avoiding the treated areas. They may relocate to another part of the room or go deeper into hiding spots. Moreover, peppermint oil doesn’t affect eggs, which continue hatching and restarting the cycle.
Comparing Peppermint Oil and Cedarwood Oil
Let’s take a closer look at how peppermint oil stacks up against cedarwood oil, especially when targeting stubborn pests like bed bugs.

Cedarwood oil works differently. Instead of simply repelling insects by scent, it disrupts the insect’s ability to breathe and interferes with their pheromone systems. This means insects become disoriented, can’t find food or mates, and leave treated areas entirely.
Benefits of Using Cedarwood Oil for Bed Bugs
If you’re looking for a natural, more effective alternative, cedarwood oil stands out. Cedar Oil Store’s products use carefully balanced formulations to ensure they are pet-safe and effective in various environments from homes to yards and even on pets.
How cedarwood oil works:
-
Targets insects' central nervous systems
-
Interferes with their sense of direction and food detection
-
Dehydrates and suffocates soft-bodied insects
-
Does not leave behind toxic residues
It’s a solution backed by both tradition and modern formulations.

Steps to Use Cedar Oil for Bed Bug Control
If you want to use cedar oil for bed bugs, consistency and thoroughness are key.
Step-by-step usage:
-
Vacuum all infested areas including carpets, mattress seams, and baseboards.
-
Apply cedar oil spray like Dr. Ben’s Evictor – Personal Use around beds, furniture, walls, and cracks.
-
Repeat treatment every 3–5 days during active infestation.
-
Launder bedding and clothes in hot water and dry on high heat.
-
Use foggers or misters for large rooms or deep penetration into furniture.
For added protection, cedar granules or sachets can be placed in drawers, closets, and under furniture.

Final Thoughts: Should You Use Peppermint Oil for Bed Bugs?
