The best essential oils for repelling pests

Essential oils can protect our homes from mosquitos, spiders, and even rats.

The best essential oils for repelling pests

One of the most common uses of essential oils is in repelling insects and household pests.

Diffusing pest-repellent oils, using them on candles or even spraying them about the home are all great ways to protect your household from pests, and you can take that protection to the next level by understanding exactly which oils are best for different kinds of infestations. Whilst many essential oils have pest-repellent properties due to their potent natural scents, some are particularly powerful. From mosquitos and ticks to ants and rats, here are some of our favourite repellent essential oils and the pests they keep at bay.

Amyris has a fresh, woody scent historically used to repel mosquitos. A purifying oil, it is able to keep these disease-carrying insects at bay and protect our health in the process. Research in 2010 also showed the oil to be repellent to two different species of ticks.
