Off! Deep Woods Insect Repellent V Spray, Unscented - 23.8% DEET
When I went to malaria-infested Southeast Asia, I was told to get this expensive bug repellent that smelled like death and worked the same if not worse than Off!. After that expensive repellent was used up, I switched to Off! I recommend using a Deet formula to really repel mosquitos but be warned that deet is a toxic chemical that can be hazardous if used too often. But I'm no health expert, I used that stuff everyday for 3 months.
