Dried Lavender
Lavender leaves repel household insects, according to the Norcross Wildlife Foundation. Sprinkle dried lavender around your home, in cabinets, on floors and anywhere you see ants.
Lavender Oil
If you know how the ants get into your home or you see an ant trail, mix one part lavender oil with ten parts olive oil and spray on the ant paths, recommends The University of Pittsburgh Cancer Institute.
Lavender Plants
Lavender plants may help repel ants found outside the home, on your lawn and in your garden. Small lavender plants may also work inside the home.
