What do I need to make your own citronella candles?

Homemade citronella candles are easy and you can use items from around the house. Candle-making supplies can be found online here. I use mason jars from the local grocery stores because they are cheap. I also save cans because I make many citronella candles for my patio.

You will need a double boiler, at least 2 ounces of citronella fragrance oil per pound of candle wax (soy). I use GB 464, “triple” scented. You will also need a pitcher to pour the wax. Keep in mind that in an outdoor space, it will require a heavily scented candle to be effective.

  • pouring pitcher
  • thermometer

How to make citronella candles

Direction:

  • Step 1: Measure the ratio of soy wax.
  • Step 2: Melt the wax to 185 F.
  • Step 3: Cool wax to 155 F, add citronella oil and stir.
  • Step 4. Cool to 135 F and pour into wicked candle jar.
  • Step 5: Place wick bar on top to center wick.
  • Step 6: Let candle sit for 48 hours min to cure, remove the bar to burn.

I like to use half-pint mason jars for homemade citronella candles. Smaller candles allow me to spread the candles around my patio and cover a larger area, more effectively. The 15-ounce vegetable cans we recycle can be saved for candles too and are free! Some have a liner that needs to be removed first.

I would stay away from terracotta pots. They often leak or seep when the candle wax melts. They don’t always handle the heat and sometimes crack leaving you with a big mess or worse a fire hazard. Make sure you are using a candle safe container when you make your own citronella candle.

Measuring the candle wax

You will need to calculate how much wax you need for the containers of your choice. I have some candle-making articles to help you figure that out. Candle making is done by weighing but homemade citronella candles can be measured with basic measuring cups.

I use 1.5 to 2 ounces of citronella oil to 1 pound of wax. That is a 10% to 12% fragrance load for soy wax.

If you are going to make many candles or make them often, buy a cheap scale. Soy wax is pretty forgiving. 2 ounces of citronella oil is about 1/4 cup with a kitchen measuring cup. A pound of wax is about 2 cups of melted wax or liquid wax with a kitchen measuring cup.

If you are making a citronella candle with beeswax, the fragrance load would be half or 3/4 to 1 ounce of citronella oil to 1 pound of wax.

Melt the candle wax

Place the candle wax in a pouring pitcher and place it in a double boiler with enough water to cover at least a couple of inches of the bottom pitcher. Place the double boiler on medium heat and bring to a low boil.

Let the wax melt until clear and the temperature reaches 185 degrees Fahrenheit. Do not over-boil and let the water run out or spill over into the wax. Remove from the heat, cool to 155 F, and add the citronella oil. Set aside to cool.

Prepare your mason jar or glass jars

For half-pint mason jars, I use HTP-105 cotton wicks 6 inches long that are pre-tabbed. Place a wick sticker or a dot of hot glue on the bottom of the wick tab and press firmly to the bottom of the mason jar. Set aside.

Pouring your homemade citronella candle

Carefully pour the wax into the mason jars leaving about 1/2″ room from the top. Place a centering tool (I use popsicle sticks) to help the wick stand upright in the center. Let the wax sit undisturbed for 12-24 hours.

Remove the wick centering tool and trim the wick to about 1/4″. Let the candle sit for another 48 hours to cure before burning. While it is curing, decorate the container. (or label)

Do citronella candles really work?

There is much debate about how citronella candles can help repel mosquitoes. In recent times, some articles have cited studies claiming citronella candles aren’t effective.

Use a combination of protection. A citronella candle and bug repellent may be needed. Using candles can help reduce the number of pests in your area but you will still need to apply a safe bug spray.

It is also a good idea to spread them out at different levels near the ground and on tabletops. They can also be used paired with citronella oils used in tiki torches or other strategies. Homemade citronella can be used in oil lamps effectively and make a great idea to keep bugs away.

Are citronella candles safe to use indoors?

Yes. Citronella is a fragrance that just so happens bugs don’t like. If you like the fresh citrus scent it’s for you. Nothing will happen if you burn a citronella candle indoors. They may be strongly scented because most people use them outside so use smaller candles or in a larger area.

Sometimes commercial citronella candles are “over wicked”, which means the wicks are oversized so that when they burn they produce more smoke. This may result in lower air quality indoors.

Larger DIY citronella candles can be made in small craft buckets. Check the bucket first to make sure it is sealed. Fill with water and check for leaks. You may have to run a bead of high-heat silicone along the seam 24 hours prior to candle making.

Place 2-3 cotton wicks equally apart and secure to the bottom, Carefully pour the wax into the bucket just as we did in this article above.

You can also use a wider heat-safe bowl to make a 3 wick of 4 wick DIY citronella candle.
