All,
I used to say that pyrethroids were safer for people--even though I was
predicting environmental harm from their increased use. But I was
wrong. The EPA risk assessment for the pyrethroid permethrin recently
came out. EPA says that permethrin is classified as "likely to be
carcinogenic to humans."
