Geranium Essential Oil for Fleas

Geranium is a pleasant-scented essential oil that has insect repelling properties against fleas, ticks and mosquitoes. This oil comes from a different cultivar of geranium plant than the potted flowers you may be used to seeing by the same name.

Some home improvement stores have begun marketing this type of geranium plant as the “mosquito plant”, but the proper name is actually geranium. It’s safe to use in essential oils form, with cats as well as dogs.

How to use geranium oil for fleas

  1. Make a flea trap to capture fleas. Add 5 to 8 drops geranium essential oil into a shallow pan (a disposable pie pan works well) filled partially with water. Shine some sort of light over the pan to lure the fleas. Empty the water with the fleas every day.
  2. Make a homemade flea repellent. Add slices of lemon to boiled water, letting it sit out overnight. Next day, pour into a spray bottle and add about 8 drops of geranium essential oil. Shake well.

    Spray on your pet, avoiding eyes, nose, mouth and groin area. You can also use geranium spray on his or her bed and any furniture where your pet may rest.
