Essential Oils for Flea Treatment. Commonly recommended essential oils for flea treatment in cats are cedar, eucalyptus and lavender. These are all well-known flea repellents that have been deemed safe when used properly. Lavender is the most common and has been shown in university studies to repel fleas.
Eucalyptus essential oil deters mosquitoes and other insects, and it works even against fleas on dogs and cats (but never use undiluted essential oils on your pets! Try a more pet-specific option for homemade natural flea repellents). Lavender is another natural mosquito repellent, and it works for other insects too.
