What’s up with all the ‘does not contain DEET’ propaganda? I’ve used products containing DEET before, should I be afraid for the safety of my unborn grandchildren or is this just another case of pandering to chemophobes? Here’s a fact: DEET was developed in the ’40s for jungle warfare and you can still buy it today in 100% concentration. Let me repeat that, Jungle. Warfare. When used as directed the safety and efficacy of DEET has been verified time and again. The EPA reassessed DEET in 1998, did extensive toxicity testing, and concluded that it does not present a health concern. And there’s no evidence that it’s even a carcinogen. Bacon can’t even make that claim, and everybody loves bacon.
