Gather Supplies: Wax, citronella oil, wicks, containers, thermometer, pouring pot, and stirring tools
To begin making your own citronella candles, the first step is to gather all the necessary supplies. The primary ingredient 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 for burn time, scent throw, and environmental impact. Soy wax is a popular choice for its clean burn and ease of use. Ensure you have enough wax to fill your chosen containers, typically measured in weight (e.g., pounds or kilograms).
Next, you’ll need citronella oil, the key component that gives your candle its insect-repelling properties. Citronella oil is derived from the leaves and stems of the citronella plant and is known for its strong, citrusy aroma that deters mosquitoes and other pests. Purchase high-quality, pure citronella essential oil to ensure effectiveness. The amount of oil needed will depend on the size of your candles and the desired strength of the scent, but a general rule is to use 6-10% of the total wax weight.
Wicks are another essential supply, as they determine how well your candle burns. Choose wicks that are appropriate for the type of wax and container size you’re using. Cotton wicks are commonly used and work well with most waxes. Ensure the wick is pre-waxed and has a sustainer (a small metal disc at the base) to keep it centered in the container. You’ll also need wick stickers or glue dots to secure the wick to the bottom of the container.
Selecting the right containers is crucial for both functionality and aesthetics. Glass jars or tins are ideal for citronella candles, as they can withstand the heat and are easy to clean if you plan to reuse them. Ensure the containers are heat-resistant and have a wide enough opening to allow for even burning. Consider the size and style of the container to match the intended use, whether for outdoor gatherings or decorative purposes.
A thermometer is an often-overlooked but vital tool in candle making. It ensures you melt the wax at the correct temperature and add the citronella oil at the right stage. Wax typically needs to be heated to around 185°F (85°C) to melt properly, and the oil should be added when the wax cools to about 135°F (57°C) to preserve its scent. A candy or digital thermometer works best for accuracy.
Finally, you’ll need a pouring pot and stirring tools to handle the melted wax safely and efficiently. A pouring pot, often made of stainless steel or heat-resistant plastic, allows you to melt the wax on a stovetop or in a double boiler. Stirring tools, such as silicone spatulas or wooden spoons, help mix the citronella oil evenly into the wax. These tools ensure a smooth pouring process and a well-blended final product. With all these supplies gathered, you’ll be fully prepared to create your own citronella candles.

Prepare Containers: Clean and dry jars or tins, secure wicks centered with glue or stickers
Before you begin pouring your citronella candle, proper container preparation is crucial for a successful and safe burn. Start by gathering your chosen containers—glass jars or metal tins work well. Ensure they are clean and free of any dust, debris, or residue from previous use. Wash them thoroughly with warm, soapy water, rinse well, and dry completely. Any moisture left behind can affect the candle’s burn quality, so allow the containers to air dry or use a clean cloth to ensure they are fully dry.
Once your containers are clean and dry, it’s time to secure the wicks. The wick is the backbone of your candle, so proper placement is essential. Begin by attaching a wick sticker to the bottom center of each container, or use a small amount of hot glue for a stronger hold. Wick stickers are adhesive discs specifically designed for candle-making and provide a reliable base for the wick. If using glue, apply a thin layer to the metal tab of the wick and press it firmly onto the center of the container’s bottom. Ensure the wick is straight and centered, as this will ensure an even burn and prevent tunneling.
For added stability, especially in larger containers, consider using a wick centering device. This tool holds the wick in place while the wax is poured and as it begins to set. If you don’t have a centering device, you can create a makeshift one by taping a pencil or wooden skewer across the top of the container and gently resting the wick on it. This will keep the wick upright and centered as the wax hardens.
After securing the wick, double-check that it remains straight and centered. A misaligned wick can cause uneven burning or difficulty in lighting. If you notice any shifting, adjust it immediately before the glue or sticker fully sets. Once everything is in place, your containers are ready for the next step in the candle-making process.
Properly prepared containers not only enhance the aesthetic appeal of your citronella candles but also contribute to their functionality and safety. Taking the time to clean, dry, and secure the wicks ensures a professional finish and a candle that burns cleanly and efficiently. With your containers prepared, you’re now set to move on to melting and pouring the citronella wax mixture.

Melt Wax: Use double boiler, heat wax to 185°F, stir until fully liquified
To begin the process of making a citronella candle, the first crucial step is to melt the wax properly. Melt Wax: Use a double boiler, heat wax to 185°F, and stir until fully liquified. Start by setting up your double boiler, which consists of a larger pot filled with water and a smaller pot or heat-safe container placed inside. This method ensures even heating and prevents the wax from burning or scorching. The double boiler technique is essential for maintaining control over the temperature, as direct heat can cause the wax to overheat and lose its quality.
Next, measure the desired amount of wax flakes or pellets and place them into the smaller pot of the double boiler. Turn the heat to medium and allow the water in the larger pot to heat up gradually. As the water warms, it will gently heat the wax, causing it to melt slowly. It’s important to monitor the temperature closely using a candy or wax thermometer to ensure the wax reaches exactly 185°F. This temperature is ideal for most candle waxes, including those used for citronella candles, as it allows for proper fragrance and additive incorporation.
While the wax is heating, prepare your workspace by gathering all necessary materials, such as the citronella oil, wick, and candle container. This preparation ensures a smooth transition once the wax is ready. As the wax begins to melt, use a heat-resistant spatula or spoon to stir it gently but consistently. Stirring prevents any hot spots from forming and ensures that the wax melts uniformly. Keep stirring until the wax is completely liquified and free of any solid chunks or granules.
Once the wax reaches 185°F and is fully melted, remove the smaller pot from the double boiler. Be cautious, as the pot and wax will be hot. Place the pot on a heat-resistant surface and allow the wax to cool slightly before adding the citronella oil or other fragrances. This step is crucial, as adding oils to wax that is too hot can cause the fragrance to burn off or evaporate, reducing the candle’s scent throw.
Finally, ensure the wax remains stirred occasionally as it cools to maintain its smooth consistency. Properly melted wax is the foundation of a successful citronella candle, providing a clean burn and even distribution of the citronella oil. By using a double boiler and heating the wax to 185°F while stirring until fully liquified, you set the stage for a high-quality, effective insect-repelling candle.

Add Citronella Oil: Mix 10-15 drops per 16 oz of wax, stir well for even distribution
When adding citronella oil to your candle-making process, precision is key to achieving the desired insect-repelling properties without compromising the candle's performance. The recommended ratio is 10-15 drops of citronella oil per 16 ounces of wax. This proportion ensures the oil is potent enough to repel insects while remaining safe for indoor and outdoor use. Always measure carefully, as using too much oil can affect the candle's burn quality and scent throw. If you're working with a larger batch of wax, scale the oil quantity accordingly, maintaining the same ratio for consistency.
To begin, prepare your melted wax by heating it to the appropriate temperature as specified by the wax manufacturer. Once the wax is fully melted and at the correct temperature, it’s time to add the citronella oil. Slowly add 10-15 drops of the oil directly into the melted wax, ensuring it is fully incorporated. Using a dropper or measuring tool can help you achieve accuracy and avoid spills. Citronella oil is highly concentrated, so a little goes a long way, and exceeding the recommended amount can lead to smoking or poor burn performance.
After adding the citronella oil, stir the mixture thoroughly to ensure even distribution. Use a heat-resistant spatula or spoon to gently but effectively combine the oil and wax. Proper mixing is crucial, as uneven distribution can result in pockets of oil that may not burn evenly or release the scent consistently. Stir for at least 2-3 minutes to guarantee the oil is fully integrated into the wax. This step is essential for creating a candle that burns cleanly and releases the citronella scent effectively.
If you’re combining citronella oil with other fragrance oils, add them at this stage as well, but ensure the total oil quantity does not exceed the wax’s recommended fragrance load (typically 6-10% of the wax weight). For a 16 oz candle, this would be approximately 1-1.6 oz of total fragrance oil, including citronella. Always prioritize the citronella oil within this limit, as it is the primary active ingredient for repelling insects. Stir all oils together until the mixture is uniform before proceeding to the next step.
Once the citronella oil is fully mixed into the wax, allow the mixture to cool slightly before pouring it into your prepared container or mold. This brief cooling period helps prevent the oil from separating or rising to the top. After pouring, let the candle set undisturbed until it is completely solidified. Properly mixing and distributing the citronella oil ensures your candle not only smells great but also functions effectively as a natural insect repellent, making it a perfect addition to your outdoor gatherings.

Pour & Cool: Pour wax into containers, let cool 24 hours, trim wicks to ¼ inch
Once your citronella wax mixture is ready, it's time for the crucial 'Pour & Cool' stage. Carefully pour the melted wax into your prepared containers. Do this slowly and steadily to avoid spills and ensure an even fill. Leave a small gap (around ¼ inch) at the top of each container to allow for wick trimming and any potential shrinkage during cooling.
Remember, the wax will be extremely hot, so use oven mitts or potholders to handle the containers and pour with caution.
After pouring, place the containers on a flat, stable surface where they won't be disturbed for the next 24 hours. This cooling period is essential for the candles to set properly. Avoid moving or bumping the containers during this time, as it can cause uneven surfaces or air pockets in the wax. Patience is key!
As the wax cools, you'll notice it changing from a liquid to a solid state. This process can take up to 24 hours, depending on the ambient temperature and the size of your candles. Resist the urge to speed up the cooling process by placing the candles in the fridge or freezer, as this can lead to cracking or uneven setting.
Once the 24-hour cooling period is complete, it's time to trim the wicks. Using a pair of sharp scissors or wick trimmers, carefully trim the wicks to ¼ inch above the wax surface. This ensures a clean, even burn and prevents the wick from becoming too long, which can cause smoking or sooting.
Trimming the wicks is a simple yet vital step in the candle-making process. It not only enhances the aesthetic appeal of your citronella candles but also promotes a safer and more enjoyable burning experience. With your candles now properly poured, cooled, and trimmed, they're almost ready to be lit and enjoyed. The final step is to test the wicks and ensure they're functioning correctly, but more on that in the next stage of the process. For now, admire your handiwork and get ready to enjoy the fruits of your labor – beautifully crafted, fragrant citronella candles.
