We’ve already told you of some ideas to help repel insects, and here’s one more idea suitable both for indoors and outdoors. To make these diffusers you’ll need 3 ounces pure beeswax, 1 tbsp coconut oil, 8 drops citronella essential oil, 8 drops geranium essential oil, 8 drops rosemary essential oil, 8 drops eucalyptus essential oil. Melt beeswax and coconut oil in a double boiler on the stove, or measuring cup set into a pan of simmering water. Once melted, remove from heat and let cool slightly, not allowing it set up. Stir in the essential oils and transfer to an ice cube tray. Place in fridge or freezer until set. Pop out the cubes and store in an airtight container.
