The "fluthrins" (cyfluthrin, fenfluthrin, etc.) are pyrethroids. The principal mode of action of pyrethroids is to interfere with nerve transmission, more specifically, by interfering with the sodium channels in nerve cells. http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=2180183&dopt=Abstract http://www.usyd.edu.au/pharmacology/pcol3001/PDF/20%20Pyrethrin%20Insecticides.pdf http://www.ehponline.org/members/2004/7254/7254.html (This article is primarily concerned with mammalian toxicity but does state: "The primary mode of pyrethroid action in both insects and mammals is disruption of VSSC function." VSSC is voltage-sensitive sodium channel.) http://www.entmclasses.umd.edu/peap/leaflets/pil42.pdf If you need to see that the fluthrins are included as pyrethoids, the structures of cyfluthrin and fenfluthrin are shown in some of the above
