So, grab your cup of hot cider, and let’s unravel the mystery of whether cinnamon can really send spiders packing!

Does Cinnamon Repel Spiders

The short answer is that there is limited scientific evidence to support the claim that cinnamon repels spiders.

While cinnamon is known for its strong aroma, which some people find pleasant and others find overpowering, there is no conclusive scientific proof that it has a significant impact on spiders’ behavior or ability to repel them.

A study published in the Journal of Economic Entomology in 2014 tested the repellency of various essential oils, including cinnamon, against the brown recluse spider.

However, the study found that cinnamon oil was not effective in repelling spiders, and they showed no avoidance behavior towards it.

Another study published in the Journal Scientific Reports in 2018 evaluated the effectiveness of cinnamon oil in repelling the common house spider.

The study found that cinnamon oil had a minimal effect on repelling spiders, and its effectiveness was significantly lower than other essential oils such as peppermint and lemon oil.

Why Does Cinnamon Repel Spiders


Cinnamon has a strong and distinct aroma that some belief may repel spiders.

It is thought that the pungent scent of cinnamon could mask the pheromones or chemical signals that spiders use to communicate with each other, potentially confusing or repelling them.


Cinnamon contains certain compounds, such as cinnamaldehyde, that may have irritant properties. 

It is possible that these compounds could cause discomfort or irritation to spiders when they come into contact with cinnamon, leading them to avoid treated areas.

Antimicrobial properties

Cinnamon has been shown to possess antimicrobial properties and may inhibit the growth of certain microorganisms. 

Some suggest that spiders, which are known to be sensitive to environmental cues, may avoid areas treated with cinnamon due to its potential antimicrobial effects.

While there is limited scientific evidence to support the effectiveness of cinnamon in repelling spiders, some people still choose to use cinnamon as a potential natural spider deterrent

Cinnamon Spray

To make a cinnamon spray, you can mix the cinnamon essential oil with water in a spray bottle.

The general ratio is about 10 to 15 drops of cinnamon essential oil per 1 cup of water.

Shake the bottle well to ensure that the oil is dispersed in the water. 

Then, spray the mixture around areas where spiders are commonly seen, such as corners, window sills, and doorways. 

It’s important to note that essential oils are concentrated and can cause skin irritation or allergic reactions, so use caution and follow safety guidelines when handling them.

Cinnamon Powder 

Cinnamon powder can be used similarly to the spray method.

Simply sprinkle the cinnamon powder around areas where spiders are known to frequent, or create a barrier with cinnamon powder along entry points, such as windowsills or doorways. 

You can also mix cinnamon powder with water to create a paste and apply it to cracks or crevices where spiders might enter.

Cinnamon Sticks 

Cinnamon sticks can be placed strategically in areas where spiders are known to be active, such as corners, closets, or under furniture. 

Some people believe that the scent of cinnamon released from the sticks may help repel spiders. You can also crush the cinnamon sticks to release more of the aroma.

Cinnamon Oil 

Cinnamon oil can be used in a diffuser or added to a cotton ball and placed in areas where spiders are commonly seen.

The diffuser can help disperse the cinnamon scent into the air, potentially making the area less appealing to spiders.
