Cinnamon with alcohol to repel mosquitoes: an unexpected homemade repellent

The unexpected duo that actually works: how cinnamon and alcohol help repel mosquitoes

Cinnamon contains aromatic compounds, especially cinnamaldehyde, which act as natural repellents for various insects, including mosquitoes. Its strong scent interferes with the receptors mosquitoes use to locate humans, making it difficult for them to identify sources of heat and carbon dioxide.

Alcohol, for its part, serves two purposes: it better extracts the essential oils from the cinnamon and helps disperse the aroma into the air as it evaporates. When combined, they create a potent and volatile infusion that acts as an olfactory barrier.

How to prepare homemade repellent

To make this mixture at home, simply combine cinnamon sticks or ground cinnamon with ethyl alcohol (70% or higher). After letting the mixture sit for at least 24 to 48 hours, you'll obtain an aromatic liquid that you can spray on windows, door frames, curtains, or areas where you often see mosquitoes. It's not recommended to apply it directly to the skin, as the alcohol can dry it out or cause irritation.

Where and when it works best

This homemade repellent works especially well in enclosed or semi-enclosed spaces, such as patios, covered terraces, or bedrooms before going to sleep. Its effectiveness increases if used preventively, particularly at dusk, when mosquitoes are most active.

You can also complement other measures: install mosquito nets, eliminate standing water, or use fans, since mosquitoes fly poorly against air currents.

Other practical and safe uses of alcohol with cinnamon

But this isn't the only benefit of this blend; it can also serve as a natural home remedy. Take advantage of the aromatic and antimicrobial properties of both ingredients with these other uses.

1. Homemade air freshener for small spaces

The blend releases a warm and comforting aroma that helps neutralize odors in closets, bathrooms, or bedrooms. You can place an open jar of the infusion or use it in a spray bottle to freshen the air.

2. Aromatic cleaner for non-delicate surfaces

Thanks to the antimicrobial properties of alcohol and the rich aroma of cinnamon, this mixture can be used as a mild cleaner for tables, handles, appliances, or non-porous surfaces. It leaves a pleasant scent and acts as a gentle disinfectant. (Avoid using on unsealed wood or delicate surfaces.)

3. Repellent for ants and some small insects

The spicy scent of cinnamon combined with alcohol also helps create an olfactory barrier against ants, especially if sprayed on door frames, windows, or areas where they usually enter.

4. Fabric spray (no skin contact)

Lightly sprayed on curtains, rugs, or bedding, it provides a warm aroma that lasts for several hours. It's advisable to test it on a corner first to ensure it doesn't stain.

5. Solution for cleaning aromatic or decorative objects

It is useful for perfuming and disinfecting items such as centerpieces, candle holders, natural fiber baskets, or autumn and Christmas decorations.

6. Infusion for lighting fireplaces or scented candles

Some people use small amounts of the mixture (never directly over a flame) to moisten twigs or decorative items before placing them in an aroma diffuser. The cinnamon aroma intensifies when heated.

7. Car air freshener

A small jar with a perforated lid or a cotton ball soaked in the mixture placed in a small bag can work as a natural air freshener for the car.

8. Add-on for eliminating bad odors in shoes

A cotton ball moistened with the mixture and placed inside the shoes overnight helps to lightly disinfect and leaves a more pleasant smell. (Avoid applying it directly to delicate materials.)

If you're looking for an aromatic, inexpensive alternative using ingredients you probably already have at home, a mixture of cinnamon and alcohol can help create a less attractive environment for mosquitoes. It's not a miracle solution, but it's a practical aid that smells delicious and keeps unwanted visitors away.
