I used 3 essential oils but there are many that you could use. I will share my recipe that I used.
4oz spray bottle
TerraSheild from doTerra 25 drops
Lavender 15 drops
Lemongrass 15 drops
In the spray bottle add the essential oils you will be using, then fill the rest up with water. I have seen and heard of using witch hazel or aloe but I want to keep it as simple as possible.
Make sure to shake before each use.
Now go and enjoy your chemical free bugs spay that you will feel comfortable using on your kids.
