Index of Subjects Respectfully, I would be more worried about that (applying a pyrethrin tea to skin) than using the permethrin treated clothing where there is not direct contact with skin. It seems there is some mis-understanding of how the permethrin-treated clothing works and how it differs from spays in regard to toxicity and environmental effects. I have made some changes on the noticks.ca page to try to explain the difference. I am certainly open to any evidence that the permethrin-treated (impreganted) clothing is NOT safe to users, and that it is hazardous to "the environment", but I have'nt seen any yet. On the other hand, there is such info. about pyrethrins and pyrethroids used as spays. See e.g., http://www.pesticide.org/get-the-facts/pesticide-factsheets/factsheets/pyrethrinspyrethrum ________________________________________ From: naturens-owner@chebucto.ns.ca <naturens-owner@chebucto.ns.ca> on behalf of Nancy P Dowd <nancypdowd@gmail.com> Sent: Tuesday, May 06, 2014 8:53 AM To: naturens@chebucto.ns.ca Subject: Re: [NatureNS] Ticks Out - the Permethrin Option One of our Lunenburg Library patrons managed to get seeds of the Pyrethrum Chrysanthemum and grew them. She brews a tea with the leaves or flowers(?) which they use to coat their skin before heading out to garden or tend their beehives. I don't know how effective this option is but it is certainly a safer one.

My beef isn't with the human health effects however. I'll leave those arguments to others.
