Biting insects can put a damper on your summer fun, not to mention potentially transmit diseases like Lyme disease and West Nile Virus... People also told Consumer Reports that safety is important when choosing an insect repellent, and
only one-third believe products on the market are safe for adults (and only 23 percent considered them safe for kids). Concern is well-justified, as DEET (N,N-diethyl- meta-toluamide) is used in hundreds of products, in concentrations of up to an astounding
100 percent.
