Pennyroyal has traditionally been used to help deter insects and support household protection in environments where pests were common. In ancestral home care, the plant was often placed around sleeping areas, window frames, or bedding to help keep insects away.
Elders valued pennyroyal for its strong aromatic oils, which helped create a natural barrier in homes where exposure to mosquitoes and other biting insects was a constant concern.
