Is deet dangerous?

Answer:
Deet has been shown to cause brain-cell death and possible behavioral changes in rats after frequent and prolonged exposure. I was unable to find the actual study so I am unsure of the amounts and frequency or types of exposure used in the study however. anything can be toxic in large amounts.
