Crazy Chicken Lady 10 Posted August 28, 2023 Share Posted August 28, 2023 Re-dose? It says effective.in 3-5 days. most of the lice are dead but there are still a few crawling about (horrible things - for what reason are they on this earth!!) Anyway do I re-dose, has anyone ever had any left alive and re-dosed? Quote Link to comment Share on other sites More sharing options...
