6 oz distilled water
5 drops eucalyptus essential oil
5 drops lavender essential oil
pretty vase
diffuser reeds

Pour all ingredients into the vase.
Insert diffuser reeds.
Turn the reeds every 2-3 hours to keep a high level of flying pest repellent in the air.

Note
This also makes a wonderful, inexpensive gift. Package the vase, a bottle of distilled water, the oils and diffuser reeds in an attractive basket, box, or gift bag and make someone very happy!
