[QUOTE="redcowsrule33, post: 632584, member: 8629"] Most avermectins have some persistent activity against lice. Moxidectin (Cydectin) has been shown to have 42 day persistency (see the abstract at [url=http://cat.inist.fr/?aModele=afficheN&cpsidt=13528560]http://cat.inist.fr/?aModele=afficheN&cpsidt=13528560[/url]). Others probably do, too, but I don't have time to research it right now. Pyrethrins such as UltraBoss and other insecticides need to reapplied for the exact reason dun stated. Different medications, same drug family (ivermectin, doramectin, moxidectin, eprinomectin are all of the avermectin class). Like aspirin and ibuprofen are both NSAIDs but there are some differences in how they work. BTW most avermectins are in fact labeled for both biting [i]and[/i] sucking lice. [/QUOTE]
