How to Use Your Oil Diffuser to Naturally Repel Bugs

Author: Emma Grace Crumbley, Entomologist 

Even though they don’t have noses, insects have a keen sense of smell. While this can help them find resources like food and water, it can also deter them when they smell something they don’t like. Do you have an oil diffuser? Use it to repel bugs!

Tip #1 – Know Your Diffuser

There are many types of essential oil diffusers you can use to emit aromas. Some diffusers require water to create an aromatic mist, while others use heat to evaporate the essential oils. Whichever kind of diffuser you prefer, make sure you know what it needs to work: water, batteries, an outlet, or scent oils. Additionally, essential oils evaporate quickly, so a consistent mist flow is necessary to create a repellent barrier in the air column. If your diffuser has an automatic timer that will turn it off, be sure you set it for the suitable duration. And keep your diffuser full for as long as you plan to use it.

Tip #2 – Choose the right scent

Many types of essential oils are available that are non-toxic to people, pets, and children. Take time to find a scent profile you enjoy that will work against insects. The EPA has registered citronella, lemon, and eucalyptus oils for their repellent uses, and other scents such as lavender, lemongrass, and cedar are known for short-term repellency. Mixing essential oils to create a blended scent may be more potent than using one flavor alone.

Tip #3 – Location, Location, Location

One downside to oil diffusers is that they’re stationary. Unless you plan on carrying your diffuser around your yard or on your daily walk, the repellent zone created by your diffusers will only cover the immediate area around it. Carefully consider where you want to place your diffuser depending on your needs and the weather. Outside spaces can be good for diffusers… until heavy winds blow the mist away. Consider using diffusers for porches, patios, and covered decks as opposed to out in the open of your yard.

Tip #4 – Keep your Diffuser Clean

Like any device, oil diffusers need to be cleaned regularly. Essential oil buildup can cause your diffuser to get clogged, and water trapped in the diffuser can mold if not regularly changed out. Make it a habit to take your diffuser apart and clean out chambers, reservoirs, and vents regularly.
