Garlic doesn’t work for me, no matter how much I eat. I prefer DEET, 100% if I can find it.
They tried to ban DEET — N,N-diethyl-meta-toluamide — in 1991 and 1992, but the chem cos intervened. NYS did ban it, with over 30% product content, since high DEET concentrations were linked to severe skin reactions and neurological problems including seizures.
