While treating a bumblefoot yesterday I had a louse crawl on me...ewwww! She was infested! Today I emptied the coop out completely and cleaned it. I did a permethrin dust on her and 3 other hens so far. I have 7 more to check/dust tonight when they go to roost. My question is... should I wait to put new bedding in until after the hens have all been treated and retreated in 5 days? I don’t want to have to throw out all the bedding again in a week if I can avoid it. Should I be doing anything else to get rid of the lice? Thanks!
