What happens if you don't wash off DEET?
What happens if you don't wash off DEET? Very often, people don't wash the product off their skin after returning indoors. This can result in overexposure, especially in cases where a product is applied too often (at short intervals) or daily for several days. A small amount of DEET is absorbed into the body when applied to the skin.
Should you spray DEET on clothes or skin?
Don't spray it near your eyes or mouth. Instead, spray it on your hands, then rub it on your face. Don't let young children apply repellent themselves. Also, repellent should be applied only to exposed skin, not to skin that will be covered by clothing.
