I have been successfully keeping red mite at bay in my large walk due in hen house, by using Vaseline on the perch ends & all nooks & crannies, also liberal user of diatom earth EVERYWHERE!
But,
Due to illness I hadn't deep cleaned my henhouse for a month,& so now I have a bit of an outbreak of the mites in there. I have some creosote, but due to the weather I wondered if there was anything guaranteed to kill them instantly, which doesn't involve leaving the hens outside for days in this torrential rain we are having?
Thank you
