Combine cedarwood essential oil, witch hazel, and swirl in a bottle to combine. Top off the bottle with water.
Shake each time before use and spray on cedarwood planks, walls, blocks, hangers to freshen up the cedar. It also helps to lightly sand the planks a little, wipe clean, and then spray with cedar spray.
I do this in spring and fall and have never had a problem with moths or other pests!
