I saw one of these on one of my turkeys about 3-4 months ago. It disappeared before I could catch it and I never found any more. I assumed it was just some kind of freakishly large common poultry louse. Then I found these on one of my peafowl today. Realizing it was the same thing, I just grabbed the three or four feathers they were crawling on and pulled them out (sorry Sweet Pea!). I managed to catch two of them on the feathers. They are flat, brown with black stripes, shaped like a bowling pin, and freakishly huge - about 2-3 times the size of an adult fowl louse. Can anyone help with a species ID? Will permethrin dust kill them?
