This is a well-written research article about effect of DEET.
Gist:
1. Oral ingestion of DEET is worse than skin absorption.
2. DEET concentration of higher 30% is not recommended because the duration of action plateaus out at 50%.
3. Repellent with 10% of DEET is good for 3 hours and more effective than any other type.
