... Try a plant-based repellent first. Examples include Repel Lemon Eucalyptus ($8) (which has a synthetic version of a naturally occurring chemical) and Natrapel or other products that contain 20 percent picaridin (a chemical similar to a compound in black pepper). In our 2010 tests (ratings chart below), both worked for at least 7 hours, though the Repel product has since been reformulated with less of the active ingredient and so no longer appears in our ratings chart. The risk of side effects for both is low, but the national Centers for Disease Control and Prevention says not to use the Repel product on kids younger than 3.
When you use deet, keep levels low. If a product with 15 percent deet keeps bugs away for 8 hours or more, as our tests found, one with 98 percent deet has to be even better, right? Actually, no. Off Deep Woods Sportsmen mini pump spray (98 percent deet) is claimed to provide maximum-strength protection for up to 10 hours. But products with 95 percent or more deet have been linked with serious side effects, including seizures, slurred speech, and coma. It can also cause eye irritation and allergic reactions. Our experts recommend using no more than 30 percent deet, ever. If you’re, say, on an overnight camping trip and need long-term bug protection, reapply a product with 15 percent deet (such as Off FamilyCare Smooth & Dry spray) and use it sparingly. Each application will protect you from mosquito and tick bites for at least 8 hours.
Think twice about using deet if you’re in a high-risk group. Children, seniors, and people with weakened immune systems should use deet only with extra caution. The American Academy of Pediatrics says not to use it at all on infants younger than 2 months.
Apply repellents outdoors, and only to clothing or exposed skin. Wash repellents off before you go to bed, and wash clothes before you wear them again.
