Having farm animals provides many benefits. However, along with the fleece, the milk and the eggs, we also have a LOT of flies. Just sitting on the porch can become a trial. This spring, I am going to try using essential oils as a deterrent.

Clean out a small tin with a lid. This will be the "home," so to speak, for your repellent.
Take a clean piece of cloth or a small piece of dish sponge able to fit into the container. Saturate it with one of the following oils (after it has been diluted appropriately, see Tips):
Lavender oil - lavender is considered to be particularly effective against flies
Citronella oil (dilute with water first)
Eucalyptus oil (dilute with water first)
Pennyroyal oil (dilute with water first)
Peppermint oil (dilute with water first; likely more effective against mosquitoes but also considered to work against horse-flies.
Lemongrass oil (dilute with water first)
Place the cloth in the tin and shut the lid. Allow to sit for 24 hours.
Use as needed. Whenever you need to use the tin, remove the lid and place on the entertaining table. Make as many as you wish to put around the entertaining area to deter flies.
Replenish the oil after each use; once open to the air, the strength weakens and needs to be topped up.
