Ants are generally harmless, but an infestation of these pests can be inconvenient and unsanitary. Though commercial ant killers are available, they are also generally made of toxic chemicals that aren't the best to have around if you have pets or children. It's easy to get rid of ants using eucalyptus oil. This natural ant repellent can be used both inside and outside. The smell of eucalyptus oil is usually enough to drive ants away completely.
Pour about 1 tsp. of eucalyptus oil onto the corner of a soft rag. Wipe down surfaces where the ants tend to appear, such as countertops, cupboards and around baseboards.
Put about 20 drops of eucalyptus oil into a clean spray bottle. Add 2 cups of warm water to the bottle, screw on the cap and shake to mix.
Spritz the natural ant repellent on items affected by the ant problem, such as on houseplants, around doorways and in showers. This eucalyptus oil ant repellent can also be easily used in outdoor areas, such as on the patio or in the garden.
Repeat the eucalyptus oil treatments about once a week, or until you no longer see evidence of an ant infestation.
