WHERE DO YOU BUY THE PYRETHRIN?Replied By Diamond (Salisbury, Ma.usa) on 04/04/2011
Joe; Pyrethrin is highly toxic to all animals, therefore it's impossible to be a natural substance for anyone, much less animals. Thanks & good luckReplied By Michelle (Riverside, California) on 08/02/2011
Pyrethrin is considered natural as it is derved from a flower The poison you can make from tomatoe plants is deadly toxic but is still considered natural.Replied By Pamela (Texas) on 11/14/2016
The pyrethrins is the main ingredient in many of your household flea killers. And most warning labels tell you NOT to expose pets to this chemical no matter where it originated. Who knows what may happen along the line later.Replied By Lynnie (Ohio) on 04/29/2018
Just got to say, I have used Pyrethrins all over while outside a lot, for many years, on my legs, arms everywhere, I never had a negative reaction to it, I use it on my dogs and cats, with no problems, people say not to use on cats, but never had a problem, it is a 'plant' based insecticide, I am good friends with a Chemistry professor and he even agreed, unless the person or animal is allergic to it, it is considered safe...
