Expert Response
There is no research that I am aware of that demonstrates that peppermint oil could act as a repellant against wasps. There is research showing that peppermint oil can be used to kill some insects and mites. However, as I mentioned, there is no evidence that it is an effective repellant of any insects, including wasps.
