Do Citronella Candles Actually Work?

Yes, Citronella candles actually works. 

In this article we are going to be looking at what Citronella is, how to use it and some commonly asked questions about it.

What Exactly is Citronella?

Citronella is a type of plant and its essential oil that is commonly known for its distinct lemony scent. It belongs to the Cymbopogon genus, which includes various species of grasses that are rich in aromatic oils.

The most well-known species of citronella are Cymbopogon nardus and Cymbopogon winterianus.

Citronella oil is extracted from the leaves and stems of these plants and is widely used for its insect-repellent properties.

It is often found in candles, lotions, sprays, and other products designed to deter mosquitoes and other insects. The scent of citronella is known to mask the scents that attract insects, thus reducing their presence in the vicinity.

In addition to its use as an insect repellent, citronella oil has been used in traditional medicine for its potential antifungal and anti-inflammatory properties.

It's important to note that while citronella is generally considered safe for external use, some people might be sensitive to the oil and could experience skin irritation.

Overall, citronella is valued for its aromatic qualities and its role in helping to keep insects at bay, making it a popular choice for outdoor gatherings and activities, particularly in areas where mosquitoes and other pests are prevalent.

Oil of lemon eucalyptus sprays reduced mosquito attractiveness by 60% at a distance of 1 metre.

Benefits of Citronella

Citronella offers several benefits due to its unique properties and aromatic qualities. Here are some of the key benefits of citronella:

1. Insect Repellent: One of the most well-known benefits of citronella is its ability to repel insects, particularly mosquitoes. The scent of citronella masks the scents that attract insects, making it a natural and effective way to keep mosquitoes and other pests at bay. This is why citronella is commonly used in outdoor candles, sprays, and lotions during warm months.

2. Natural and Non-Toxic: Citronella is a natural alternative to chemical insect repellents. It is generally considered safer for humans and the environment compared to some synthetic repellents that contain potentially harmful chemicals.

3. Aromatherapy: The fresh, lemony scent of citronella is often used in aromatherapy to promote relaxation and create a pleasant atmosphere. It can help uplift moods and reduce feelings of stress and anxiety.

4. Antifungal Properties: Citronella oil has been studied for its potential antifungal properties. It may help inhibit the growth of certain types of fungi, making it useful in addressing fungal infections or preventing their occurrence.

5. Anti-Inflammatory Effects: Some studies suggest that citronella oil might have anti-inflammatory properties when applied topically. It could be beneficial for soothing skin irritation and redness caused by inflammation.

6. Repelling Pets from Restricted Areas: Citronella's strong scent can also be used to deter pets from entering specific areas of your home or garden where they're not allowed. This can help with training and maintaining boundaries for your pets.

7. Lawn and Garden Care: Citronella plants can be cultivated in gardens as ornamental grasses. Their presence can help reduce the population of insects in the surrounding area, providing a natural form of pest control.

8. Candles and Outdoor Use: Citronella candles are commonly used in outdoor spaces to create a bug-free zone for social gatherings, picnics, and outdoor dining. These candles release the scent of citronella into the air, helping to deter insects from approaching.

9. Scented Products: The pleasant aroma of citronella makes it a popular choice for scented products such as soaps, shampoos, and lotions. These products not only offer potential insect-repelling benefits but also leave a refreshing fragrance on the skin.

How Many Citronella Candles Do You Need?

The number of citronella candles you need depends on several factors, including the size of the area you want to protect, the severity of the insect problem, and the type of citronella candle you're using.

Here are some general guidelines to help you determine how many citronella candles you might need:

1. Size of the Area: Larger outdoor spaces will require more citronella candles to effectively repel insects. If you're protecting a small patio or deck, one or two candles might be sufficient. For larger gardens or picnic areas, you may need several candles spaced strategically.

2. Candle Potency: Citronella candles come in various strengths, and some may have a stronger scent and repellent effect than others. Consider the potency of the candles you're using; stronger candles might require fewer to cover the same area.

3. Wind and Airflow: Windy conditions can disperse the scent of citronella more quickly, reducing its effectiveness. In such cases, you might need more candles to counteract the wind and maintain a protective barrier.

4. Insect Density: If you're dealing with a particularly heavy insect infestation, you might need to use more citronella candles to effectively repel the insects and create a bug-free zone.

5. Duration: Consider how long you plan to be outdoors. If you're having a short gathering, a few candles might be enough. For longer events, you might need additional candles to ensure continuous protection.

As a rough guideline, for a small outdoor area like a patio or balcony, one or two citronella candles might suffice. For larger spaces like a backyard or garden, you might need multiple candles spread out strategically.

It's often a good idea to start with a couple of candles and observe their effectiveness. If you notice insects are still present or the protection is inadequate, you can add more candles as needed.

Remember that individual preferences and experiences can vary, so you may need to adjust the number of candles based on your specific situation and comfort level.

Can You Burn Citronella Candles Indoors?

While it's possible to burn citronella candles indoors, there are certain considerations you should keep in mind before doing so:

1. Ventilation: Indoor spaces are typically less ventilated than outdoor areas. Burning candles, including citronella candles, can release smoke and potentially affect indoor air quality. Make sure you have adequate ventilation by opening windows or doors to allow fresh air to circulate.

2. Fire Safety: Always prioritise fire safety when using candles indoors. Keep citronella candles away from flammable materials, and place them on stable surfaces away from drafts or items that could easily catch fire.

3. Scent Concentration: The scent of citronella can be quite strong, especially in enclosed spaces. Some people might find the aroma overwhelming, and it could compete with the overall indoor atmosphere.

4. Sensitive Individuals: Some individuals may be sensitive to the strong scent of citronella, and it could cause headaches, respiratory discomfort, or other adverse reactions. If you or anyone in your household has sensitivities or allergies, it's important to consider their well-being.

5. Insect Repellent Effectiveness: Citronella candles work by releasing their scent into the air, creating a protective barrier against insects. In indoor settings, the effectiveness of citronella candles in repelling insects might be limited, especially if the space is well-sealed and insect entry points are minimal.

What to Look for in a Citronella Candle

When looking for a citronella candle, there are several factors to consider to ensure you choose a product that meets your needs and expectations. Here's what to look for in a citronella candle:

1. Citronella Content: Check the label to ensure that the candle contains a sufficient amount of citronella oil. The higher the citronella content, the more effective the candle will likely be at repelling insects. Look for candles that clearly state the percentage of citronella oil in the product.

2. Quality of Ingredients: Opt for candles made from high-quality ingredients, including natural citronella oil. Avoid candles that contain synthetic fragrances or additives that might diminish the effectiveness of the citronella.

3. Burn Time: Consider the burn time of the candle. Longer burn times are convenient, as they reduce the need to replace the candle frequently. However, keep in mind that burn time can vary based on factors like candle size and wind conditions.

4. Type of Candle: Citronella candles come in various forms, such as votive candles, pillar candles, and container candles. Choose a type that suits your preferences and fits the intended use. Container candles are often more practical for outdoor use as they protect the flame from wind.

5. Size and Quantity: The size of the candle and the quantity you need depend on the size of the area you want to protect. Larger spaces may require larger candles or multiple candles placed strategically.

6. Wind Resistance: If you plan to use the candle outdoors, consider candles that are designed to withstand wind. Look for options with wind-resistant containers or lids that help protect the flame from being extinguished.

7. Safe Burning: Ensure the candle is designed for safe burning. Look for features like stable bases, non-flammable containers, and clear safety instructions on the label.

8. Additional Repellents: Some citronella candles might include additional natural repellents like eucalyptus, lemongrass, or rosemary. These ingredients can enhance the insect-repelling effect of the candle.

9. Reviews and Recommendations: Read reviews and recommendations from other customers to gauge the effectiveness and quality of the citronella candle you're considering. This can provide insights into real-world experiences.

10. Environmental Considerations: Opt for candles that are environmentally friendly and use sustainable materials. Look for options that are free from harmful chemicals and are made from renewable resources.

11. Aesthetics: Consider the visual appeal of the candle, especially if you're using it for outdoor gatherings. A nicely designed candle can contribute to the overall ambience.

12. Price: While price shouldn't be the sole factor, it's worth comparing different options to ensure you're getting good value for the quality and effectiveness of the product.

Remember that individual preferences and needs vary, so choose a citronella candle that aligns with your specific requirements and the intended use, whether it's for repelling insects during outdoor activities or simply enjoying the aroma indoors.

Where to Put Citronella Candles

Placing citronella candles strategically is important to maximise their effectiveness in repelling insects and creating a bug-free environment. Here are some key locations to consider when placing citronella candles:

1. Outdoor Seating Areas: Place citronella candles near outdoor seating areas, such as patios, decks, and balconies. Position them on tables, ledges, or stable surfaces where they can create a protective barrier against insects while you and your guests enjoy the space.

2. Entrances: Position citronella candles near entrances to your home, particularly doorways and windows. This can help deter insects from entering indoor spaces when doors are open.

3. Around Gathering Spaces: If you're hosting an outdoor event or party, place citronella candles strategically around the gathering space. This could include areas where food and drinks are served, as well as spots where guests might congregate.

4. Around Water Features: If you have a pool, pond, or other water feature in your garden, consider placing citronella candles nearby. Water sources can attract insects, so having candles in these areas can help keep pests at bay.

5. Around Plants: Position citronella candles near plants and flowers, as some insects are drawn to plant fragrances. This can help protect both your plants and the people enjoying your outdoor space.

6. Breezy Areas: Wind can disperse the scent of citronella, reducing its effectiveness. Place candles in areas that are less windy, or use wind-resistant containers to protect the flame.

7. Outdoor Dining Tables: If you're having a meal outdoors, place citronella candles on the dining table to create a bug-free dining experience.

8. Insect Entry Points: Position candles near common points of entry for insects, such as gaps in fences, areas with dense vegetation, and locations where insects are known to congregate.

9. Elevated Surfaces: Placing citronella candles on elevated surfaces, such as shelves or raised platforms, can help spread the scent over a wider area.

10. Around Play Areas: If you have outdoor play areas for children, consider placing citronella candles nearby to protect them from insect bites.

11. Around Cooking Areas: If you have an outdoor kitchen or barbecue area, use citronella candles to deter insects while you cook and prepare food.

12. Larger Spaces: For larger outdoor spaces, you might need to use multiple candles spaced out strategically to ensure consistent coverage.

Remember that citronella candles create a protective barrier through their scent, so their effectiveness can be limited by factors such as wind, rain, and the size of the area you're trying to protect. It's a good idea to observe how the candles perform in your specific setting and adjust their placement as needed to achieve the best results.
