Gather Supplies: Wax, citronella oil, wick, container, thermometer, pouring pot, and fragrance (optional)
To begin making your own citronella candle, you'll need to gather all the necessary supplies. The primary component is wax, which serves as the base of your candle. You can choose from various types of wax, such as soy wax, paraffin wax, or beeswax, depending on your preference and availability. Soy wax is a popular choice due to its clean burn and eco-friendly nature. Ensure you purchase enough wax to fill your desired container, typically measured in weight (e.g., pounds or kilograms).
Next, you’ll need citronella oil, the key ingredient that gives the candle its insect-repelling properties. Citronella oil is derived from the leaves and stems of the citronella plant and is widely available in craft stores or online. When selecting citronella oil, opt for a high-quality, pure essential oil to ensure effectiveness. Keep in mind that the amount of oil needed will depend on the size of your candle and the desired strength of the scent.
A wick is another essential supply, as it allows the candle to burn properly. Choose a wick that is appropriate for the type and size of your container. Cotton wicks are commonly used and work well with most waxes. Some wicks come pre-tabbed with a metal base, making it easier to center them in the container. If your wick doesn’t have a tab, you’ll need wick stickers or a small amount of melted wax to secure it in place.
Selecting the right container is crucial, as it will hold the wax and define the candle’s appearance. Glass jars, tins, or ceramic containers are excellent choices, but ensure they are heat-resistant and can withstand the temperature of the melted wax. Consider the size and style of the container to match your intended use, whether it’s for outdoor gatherings or home decor. If you plan to reuse a container, clean it thoroughly to remove any residue.
A thermometer is an often-overlooked but vital tool in candle-making. It ensures that the wax is heated to the correct temperature, which varies depending on the type of wax used. Overheating wax can affect its quality and scent throw, so monitoring the temperature is essential. A candy or kitchen thermometer with a clip works well for this purpose, allowing you to attach it to the side of your pouring pot.
Speaking of the pouring pot, this is a heat-safe container used to melt the wax. A stainless steel or glass pouring pitcher is ideal, as it allows for easy and controlled pouring. If you don’t have a dedicated pouring pot, a clean, dry saucepan can be used, but be cautious to avoid contamination. Finally, consider adding a fragrance (optional) to complement the citronella scent. Popular options include lavender, lemon, or eucalyptus, which can enhance the aroma and create a more pleasant atmosphere. Ensure any additional fragrance oil is compatible with the wax you’re using. With all these supplies gathered, you’ll be well-prepared to start crafting your citronella candle.

Prepare Container: Clean and dry the container, secure the wick at the center
Before you begin making your citronella candle, it's essential to prepare your container properly. Start by selecting a suitable container, such as a glass jar or tin, that can withstand heat and is free from any cracks or damage. The size of the container will depend on the amount of wax you plan to use and the desired size of your candle. Once you've chosen your container, clean it thoroughly with warm, soapy water to remove any dirt, dust, or debris. Rinse the container well and dry it completely with a clean towel or allow it to air dry. It's crucial to ensure that the container is entirely dry before proceeding, as any moisture can affect the candle's performance and potentially cause issues during burning.
After cleaning and drying the container, the next step is to secure the wick at the center. The wick is a critical component of your candle, as it will be responsible for drawing the melted wax up to the flame. To secure the wick, you'll need a wick sticker or a small amount of hot glue. Apply the adhesive to the bottom of the wick tab, then press it firmly onto the center of the container's bottom. Make sure the wick is straight and centered, as this will ensure even burning and prevent the candle from tunneling or burning unevenly. If your container is curved or has a rounded bottom, you may need to use a wick holder or pencil to keep the wick in place while the adhesive sets.
While securing the wick, consider the type of wick you're using, as different wicks are suitable for various wax types and container sizes. For citronella candles, a medium to large-sized wick is generally recommended, depending on the diameter of your container. If you're unsure about the appropriate wick size, consult the manufacturer's guidelines or seek advice from a candle-making supplier. Proper wick selection is vital for achieving a clean burn, maximizing fragrance throw, and ensuring the overall quality of your citronella candle.
Once the wick is securely in place, double-check its positioning and make any necessary adjustments. A slightly off-center wick can be corrected by gently lifting the tab and reapplying the adhesive. Take your time during this step, as a well-centered wick will significantly impact the final product's appearance and performance. If you're using a container with a narrow opening, you may find it helpful to use a pair of tweezers or a small tool to adjust the wick's position without disturbing the adhesive.
In addition to securing the wick, consider preparing your workspace and gathering all the necessary materials before proceeding with the candle-making process. This includes having your wax, citronella oil, fragrance oils (if desired), and any colorants or additives ready. By taking the time to prepare your container and secure the wick correctly, you'll set a solid foundation for creating a high-quality citronella candle that burns cleanly, smells fantastic, and repels insects effectively. With the container prepared and the wick in place, you're now ready to move on to the next steps of melting the wax and adding the citronella oil.

Melt Wax: Use a double boiler to melt wax to 185°F (85°C)
To begin the process of making a citronella candle, one of the crucial steps is melting the wax, and using a double boiler is an effective and safe method to achieve this. Start by setting up your double boiler system. If you don’t have a dedicated double boiler, you can easily create one by placing a heat-resistant glass bowl or a metal pitcher over a saucepan filled with a few inches of water. Ensure the bowl or pitcher fits snugly on the saucepan without touching the bottom, as this allows for indirect heat, preventing the wax from overheating or burning.
Once your double boiler is ready, measure out the amount of wax you need for your citronella candle. Soy wax, paraffin wax, or a blend of both are commonly used for candle-making. Place the wax into the top part of the double boiler. Turn the stove to medium heat and allow the water in the saucepan to heat up gradually. As the water warms, it will gently melt the wax in the bowl above. This method ensures even melting and reduces the risk of scorching the wax, which can affect the quality of your candle.
While the wax is melting, monitor the temperature using a candy or wax thermometer. Insert the thermometer into the wax, ensuring it does not touch the bottom or sides of the bowl for an accurate reading. The goal is to melt the wax to 185°F (85°C), which is the ideal temperature for adding essential oils and preparing the wax for pouring. Stir the wax occasionally with a heat-resistant spatula to promote even melting and prevent any clumps from forming.
As the wax approaches 185°F (85°C), keep a close eye on the thermometer to avoid overheating. Once the desired temperature is reached, remove the bowl from the double boiler. If you’re using a glass bowl, place it on a heat-resistant surface or a towel to prevent it from cracking. Allow the wax to cool slightly, but not solidify, before adding the citronella essential oil. This step is crucial for ensuring the oil blends evenly with the wax, providing a consistent scent throughout the candle.
Using a double boiler to melt wax to 185°F (85°C) is a fundamental step in making a citronella candle. It ensures the wax is properly prepared for the next stages of the process, such as adding fragrance and pouring into the container. By following this method carefully, you’ll achieve a smooth, well-blended wax base that will result in a high-quality, long-lasting citronella candle. Always prioritize safety by handling hot wax with care and using appropriate tools to monitor temperature and stir the mixture.

Add Citronella Oil: Mix 10-15 drops of citronella oil per 8 oz of wax
When making a citronella candle, adding the right amount of citronella oil is crucial for achieving both the desired scent and insect-repelling properties. The general guideline is to mix 10-15 drops of citronella oil per 8 oz of wax. This ratio ensures the candle emits a strong enough aroma to deter insects without overwhelming the senses. Always use high-quality, pure citronella essential oil for the best results, as synthetic or low-quality oils may not be as effective. Before adding the oil, ensure your wax is at the correct temperature (usually around 185°F or 85°C) to allow for proper blending.
To incorporate the citronella oil, first measure the wax accurately and melt it in a double boiler or a dedicated wax melter. Once the wax reaches the recommended temperature, remove it from the heat source and let it cool slightly to around 135°F (57°C). This temperature is ideal for mixing in the essential oil without causing it to evaporate prematurely. Slowly add 10-15 drops of citronella oil per 8 oz of wax, stirring gently but thoroughly to ensure even distribution. Avoid over-stirring, as this can introduce air bubbles into the wax, affecting the candle's appearance and burn quality.
The amount of citronella oil (10-15 drops per 8 oz of wax) can be adjusted slightly based on personal preference or the size of the candle. For larger candles or outdoor use, you may lean toward the higher end of the range (15 drops) to maximize the insect-repelling effect. Conversely, for smaller candles or indoor use, 10 drops may suffice to maintain a pleasant scent without being overpowering. Always test a small batch first to ensure the scent strength meets your expectations before making a larger quantity.
It’s important to note that citronella oil is highly concentrated, so precision in measuring is key. Use a dropper or measuring tool to add the exact number of drops, as too much oil can cause the candle to smoke excessively or burn poorly. Additionally, avoid adding the oil directly to the wick or container, as this can interfere with the candle's performance. Instead, mix it thoroughly into the melted wax before pouring it into the container. This ensures the citronella oil is evenly dispersed throughout the candle, providing consistent fragrance and effectiveness.
Finally, after adding the citronella oil, allow the wax to cool slightly before pouring it into your chosen container. Secure the wick in place and let the candle set completely, which can take several hours. Once fully hardened, trim the wick to about ¼ inch for optimal burning. By following the 10-15 drops per 8 oz of wax guideline and these steps, you’ll create a citronella candle that not only smells great but also serves its practical purpose of keeping insects at bay.

Pour & Cool: Pour wax into the container, let it cool for 24 hours
Once your citronella wax mixture has reached the optimal temperature (typically around 185°F or 85°C), it’s time to carefully pour it into your chosen container. Ensure your wick is centered and securely held in place using a wick holder or a pencil laid across the container’s rim. Slowly and steadily pour the melted wax into the container, leaving about ¼ to ½ inch of space at the top. Pouring too quickly can create air bubbles or cause the wick to shift, so take your time and maintain a consistent pace. If you notice any bubbles forming on the surface after pouring, gently tap the container on a flat surface or use a toothpick to pop them.
After pouring, allow the candle to cool undisturbed at room temperature for at least 24 hours. This cooling period is crucial for the wax to set properly and ensure a smooth, even finish. Avoid moving or disturbing the container during this time, as it can cause the wax to crack or the wick to become misaligned. If your workspace is prone to drafts or temperature fluctuations, consider covering the candle loosely with a clean cloth or placing it in a draft-free area to maintain consistent cooling conditions.
During the cooling process, you may notice the wax pulling away slightly from the edges of the container—this is normal and part of the curing process. As the wax hardens, it contracts, creating a small gap between the wax and the container walls. This does not affect the candle’s performance and is a sign that the wax is setting correctly. Be patient and resist the urge to speed up the cooling process by placing the candle in the refrigerator or freezer, as rapid cooling can lead to uneven surfaces or cracks.
Once the 24-hour cooling period has passed, inspect your candle to ensure the wax has fully hardened and the wick remains centered. If the surface appears uneven or sunken, you can carefully reheat the wax to around 200°F (93°C) and pour a small amount into the dip to even it out. Allow this additional wax to cool completely before proceeding. Proper cooling is essential for the longevity and burn quality of your citronella candle, so take the time to do it right.
After the candle has fully cooled and set, trim the wick to about ¼ inch above the wax surface. This ensures a clean, even burn when you light your citronella candle. Now your handmade citronella candle is ready to use, providing both a pleasant aroma and natural insect repellent properties. Enjoy the fruits of your labor and the ambiance it brings to your outdoor spaces!
