- DEET is the active chemical ingredient in most insect repellents available in the United States.
- It is used to repel such biting pests as mosquitoes and ticks-including ticks that may carry Lyme disease.
- DEET was registered in the U.S. for the general public to use in 1957.
- Generally, the higher the percentage of DEET, the longer the repellent works.
- Higher concentrations of DEET are recommended for activities that keep you outside all day in geographic regions with large populations of insects and ticks.
- Lower concentrations are acceptable when you are planning to be outdoors for only a few hours.
