Repel spiders: Place peppermint oil on a cotton ball or cotton pad and place in areas where you find spiders. You can also make a spider spray repellent. Add 4-5 drops of the oil to water in a spray bottle. Make sure it has a strong peppermint scent, and spray in areas you want to repel spiders. Check out Momasuarus for more about repelling spiders naturally–be sure to watch her great video too!
Gets rid of Aphids: Add drops of peppermint oil to a spray bottle of water and spray plants to kill aphids.
Relieves itching: Apply peppermint oil to bug bites to stop itching. (don’t apply to open sores, it will burn!)
