Spray Peppermint Oil

If you prefer not to fill your home with plants, peppermint essential oil is a convenient alternative.

How to use it:

Dilute a few drops of peppermint essential oil with water in a spray bottle.

Spray along baseboards, in corners, near entry points, and in dark spaces.

Reapply regularly, as the scent fades over time.Biological Sciences

A gentle caution: If you have pets or small children, use peppermint oil with care. It can be toxic in high doses, so keep the bottle out of reach
