Citronella oil has long been used for many purposes, including as a natural insect deterrent [source]. In this version of citronella diffusers, beeswax is melted down with a carrier oil and combined with essential oils to create wax candle melts to use outdoors.
They are super easy to make and as an added bonus, the wax never evaporates! This means that they can be used over and over and over again, adding more essential oils as needed.
How to make wax melts
The oil blend I’ve used contains citronella, geranium, rosemary and eucalyptus, all of which are frequently found in natural insect repellent recipes.
Here’s how you make the wax melts:
You need 1 tablespoon of coconut oil plus 3 ounces (6 tablespoons) beeswax. If you use beeswax pellets, it melts very easily. However, bars of beeswax need to be chopped for easier melting.
Place the ingredients in a glass measuring cup and set in a pan of simmering water, stirring occasionally until melted. This can take up to 10-15 minutes depending on the temperature and beeswax.
Alternatively, you can melt it in the microwave. Whatever you do, be super careful because it gets extremely hot! Stir well so the coconut oil is combined well with the wax.
Let it cool ever so slightly and add the essential oils. Immediately pour into a mold.
Depending on the size of the wells in the mold, you should get between 6-8 small cubes. I put the mold into the freezer so the wax will set quickly.
To use, place one cube into the top of a candle diffuser and light the candle. It will take about 10-15 minutes for the wax to melt and start diffusing the essential oils. If the scent isn’t strong enough, add a few more drops of each of the oils.
Be very careful when handling the diffuser because it gets very hot. Allow it to stand until completely cool.
If you need to remove the wax, place the cooled diffuser bowl into the fridge or freezer for a few minutes and then simply pop it out. Store the cubes in an airtight container someplace cool and dry.

This is an awesome guide. Thank you!
Is this safe to use indoors?

Where did you purchase the wax diffuser? Thank you
I’d love to know where to purchase this melting pot as well??!!?!?!?!
Christina Frost says
This is fantastic! Definitely one to use next summer. Essential oils have many different functions but didn’t know that could be used as insect repellants too!
Nice recipe, thank you!
I will try it as soon as i have a free time :)
Any reason why this can’t be used indoors too?
Beeswax where I buy it? Thanks again
Quart size paint cans. Is inside black plastic or steel? Let me know Ty
Melissa @ Wellness Appliances says
the process is a new one but seems interesting, only problem is how and where can I get beeswax? and how long this can be used? when i need to refill the EO , how shall I do it?
Oh, why didn’t I found you earlier? This recepie is great, it would be so useful this summer. How about making a candle that repells insects just with those ingredients you’ve mentioned here? Have you tried this?
Lindsey Johnson says
You could make a candle with the same ingredients. It’s a very similar thing. The only difference is that the diffuser never burns the wax so it lasts for a long time.
