x2.I'm not really sure when you're supposed to do it again. Every 7-14 days until they're gone???
That's about the time external parasites hatch from eggs. That's when you want to redust the birds before the nits become adults and start reproducing/laying eggs again defeating the purpose of the dustings. I prefer to dust between 7-10 days after the initial dusting....gotta include coops and nests as well. Severe infestations may require more dustings.
