Spearmint oil

This other minty choice has a comparable scent and advantages to peppermint, so it can be considered as an alternative.

Spearmint oil has a somewhat sweeter scent than peppermint oil and has been shown to have antifungal effects. When used topically, it has the same cooling effect as peppermint, making it equally beneficial for repelling insects and soothing bug bites. Before taking spearmint oil, consult your doctor if you are pregnant or nursing.
