Deet-a cheap but effective repellent cream for protection of people overnight in forest from mosquito bite

A product with 15% DEET gave an overall bite protection of 85%, without evidence for a diminishing effect through the night. When mosquitoes had a choice at one site between people using repellent or not, the repellent had most effect (88% protection with choice and 57% - 79% without choice). A product containing 27% DEET worked significantly better with 93% overall bite protection. The 15% product is locally available, cheap (0.8 US$ for a flacon of 75ml which lasted 30 person-nights) and in the opinion of the capturers well compatible
