Does Cedar Oil Repel Bed Bugs?

While some people may have experienced success with cedar oil as a bed bug repellent, there is limited scientific backing for this claim.

 A 2014 study that specifically investigated the effectiveness of cedar oil-based products against bed bugs did not yield significant results in terms of repelling the pests.

Another study in 2015 identified other essential oil compounds, such as carvacrol, thymol, citronellic acid, and eugenol, as more effective against bed bugs, but cedar oil was not tested. 

Although cedar wood’s strong odor may have some repellent properties, there is not enough scientific evidence to support the claim that cedar oil alone is an effective bed bug repellent.

Additional research is needed to determine its efficacy against bed bugs specifically

How to Use Cedar Oil for Bed Bugs

Acquire 100% Pure Cedar Oil

Opt for premium, high-quality cedarwood essential oil that is 100% pure for optimal results.

Dilute the Cedar Oil

Blend a few drops of essential oil with a carrier oil such as coconut, olive, or grapeseed oil.

Administer the Mixture

Apply the diluted mixture to areas where bed bugs may be present, including your mattress, bedding, and nearby furniture.

For laundering sheets and pillowcases, consider adding a few drops of the mixture to your laundry detergent.

Repeat the Procedure

Reapply the mixture every few days to maintain a potent and effective scent.

Utilize Cedarwood Chips

Employ cedarwood chips in drawers and closets to repel bed bugs with their natural scent.

Place the chips directly on affected areas or in small sachets for added effectiveness.

The Harm of Using Cedar Oil

Even though cedar oil has innumerable benefits, it fails to work as effectively as any other non-natural alternatives of insect repellents. 

Also, the smell doesn’t stay for long and you would have to keep spraying the cedar oil at regular intervals of time. This makes it a tedious task to do.

Another possible threat might come from the fact that it is a tree extract. Tree extracts do not suit everyone and allergies and skin irritations are common. So, it is important to check whether or not cedar oil has any side effects in your case. 

Frequently Asked Question

Does Cedar Oil Kill Bed Bugs?

While cedar oil does exhibit insecticidal properties that could potentially kill bed bugs upon direct contact, it is not considered a highly effective means of eradicating bed bugs. 

While cedar oil may provide temporary relief or deterrence against bed bugs, it should not be solely relied upon as the sole solution for eliminating a bed bug infestation.

How Does Cedar Oil Kill Bed Bugs?

Cedar oil is believed to kill bed bugs by disrupting their respiratory system and dehydrating them. 

The oil contains natural compounds, known as sesquiterpenes, that can penetrate the exoskeleton of the bed bugs and damage their cells. This leads to dehydration and eventually death of the bed bugs.

Which Essential Oil is Best for Bed Bugs?

Carvacrol, derived from oregano and thyme; thymol (thyme); citronellic acid (lemongrass); and eugenol (clove) are the most effective essential oils for bed bugs.
