message: The opening potion of the wiki says "Use during pregnancy appears to be safe".  There needs to be a citation to affirm that statement.  — Preceding unsigned comment added by 108.228.186.84 (talk) 15:04, 10 July 2017 (UTC)

message: This is what safe2use.com says about permethrin: The U.S. Environmental Protection Agency has classified permethrin as a carcinogen because it causes lung tumors in female mice and liver tumors in mice of both sexes.
Wikipedia says permethrin is not classified as a carcinogen.
What's up with that? bstout@news-press.com 74.93.47.33 17:09, 6 June 2007 (UTC)
replies: text: Permethrins are toxic to cats and I would recommend leaving the wording as it is.  Here's a quote from the Merck Veterinary Manual "Some pyrethroids, such as permethrin, can be highly toxic to cats." .  A more detailed article can be seen at the ASPCA's Poison Control website here .  You'll note that it's talking about permethrin concentrations much higher than .050%, but those are the concentrations it's typically found at.  I'm not commenting on the safety of the Sergeant's product, but I think it's better to have a blanket statement about permethrin being toxic in cats than to try and give a safe dose (especially since I don't know what the safe dose is, only that it is very much lower than what you find in most flea products).  We can use the ASPCA article as a source if you like.  Let me know what you think.  --Joelmills 03:14, 20 September 2007 (UTC)

thread_title: Permethrin toxicity

message: Is this article respectable? Health Effects of Permethrin-Impregnated Army Battle-Dress Uniforms (1994). Should the article mention the varying toxicity of the isomers? The article does not mention its use for treating timber before building construction or when insect infested. Vernon White . . . Talk  23:13, 10 November 2007 (UTC)
thread_title: Neurotoxicity

message: I do not know if discussion of DDT is terribly relevant in this article.  If it is to remain, the section stating "given the well known risks" should be amended to specify that there are only proven risks to  certain bird and fish species and no credible evidence that links DDT exposure to negative health outcomes for humans.  Furthermore, while the article states correctly that DDT is an extremely effective insecticide, it states that it is used because it is inexpensive.  This is conjecture, DDT is used because it is the most effective, and long-lasting insecticide that can be used for indoor residual spraying (IRS)- the fact that it lasts twice as long as other insecticides certainly lends usefulness.  —Preceding unsigned comment added by 208.58.6.23 (talk) 02:04, 11 April 2008 (UTC)
replies: text: The section on DDT usage in this article reads like someone being extremely apologetic and feeling guilty about personally using it. Very weird paragraph.  —Preceding unsigned comment added by 24.95.44.134 (talk) 09:48, 9 May 2008 (UTC)

message: I have rolled back the article to its April 4 state.
The reason is that someone added a section that was apparently copied from , which contains no assertion that its content is licensed for use under the GFDL.
Please add only content that follows the rules, so that they can be legally used on Wikipedia (and its mirrors) under copyright law. --Alvestrand (talk) 08:49, 7 June 2008 (UTC)
thread_title:  Removed copyrighted section by rollback 

message: I added a line regarding the connection (via US Military study) between Parkinsons and permethrin. I also removed a line that claimed permethrin had 'low if any toxicity' which is clearly not the case. Just because it's not lethal doesn't mean it's non-toxic: it
s a documented mutagen, carcinogen, teratogen, and possibly a hepatotoxin as well.

thread_title:  Added information about Parkinson's effects of permethrin 

message: The diagram labelled (1R)-trans-permethrin (biopermethrin) is incorrect- the stereoisomer depicted is actually another (1S)-trans-permethrin. The file to which it is linked is also incorrectly labelled as biopermethrin (again, the (1R)- stereoisomer).  —Preceding unsigned comment added by 24.159.27.129 (talk) 03:04, 10 October 2009 (UTC)
thread_title:  Incorrect Diagrams 

message: The NIX disambig page states "Nix (Permethrin), Brand-name of Permethrin (anti-lice drug) in North America", as seems to be the case.  However the article itself says "In nordic countries it is marketed under trade name Nix", and mentions nothing about the use of the trademark in N. America.  I've heard "NIX" used for a scabies & lice treatment (here in Canada), and it must be referring to Permethrin, but am not knowledgeable enough on the matter to put that in myself.  Will someone please put it in if it's true, or change the disambig page if it's not.  Thanks.--Keithonearth (talk) 19:13, 23 February 2012 (UTC)

message: Would it be noteworthy to say that Permethrin may trigger Airport explosives security check? And cause unsuspecting citizens a lot of frustration?

thread_title:  Airport Check Triggers 

message: This article has a splintered array of safety related information.  Safety is sub-sub-topic under side-effects.  It then appears again as part of the sub-topic "Toxicology and Safety".  It is my humble opinion that Toxicology and Safety should be separate sub-topics, and that the information under "Side-effects / Safety" should be contained wholly within the sub-topic of "Safety".

message: There are at least a couple of studies showing an association between spraying of pyrethroids, and permethrin specifically, with autism rates.  'Neurodevelopmental Delay Diagnosis Rates Are Increased in a Region with Aerial Pesticide Application' found this to apply to zip codes in NY, and 'Tipping the Balance of Autism Risk: Potential Mechanisms Linking Pesticides and Autism' did much the same in California.  Should "safe during pregnancy" stay in the lede, and mention of these studies be omitted from the article?  199.200.120.135 (talk) 18:41, 24 July 2018 (UTC)

message: I found some slides with lots of interesting details about the use of permethrin as an insecticide on clothing (mainly military uniforms). It includes many references that appear to be reliable sources that perhaps may be used to add detail to this article.
