What percentage of DEET is best?
Deet. Many people assume that the more deet (N,N-diethyl-meta-toluamide) a product contains, the better. But our tests find that there’s no need to use higher concentrations; products with 15 to 30 percent deet can provide long-lasting protection against mosquitoes and ticks.

Does DEET melt plastic?

Should I wash off DEET?
Don’t put DEET on skin that will be covered by clothing — this will cause your skin to absorb the DEET. Once you return indoors, make sure you wash off the DEET with soap and water. It’s especially important to do this if you plan to reapply the DEET later or the next day.
Is picaridin safer than DEET?

What’s wrong with DEET?
