I got a no pest strip at the grocery store, it was in a plastic cage to keep kids from eating it (and I didn’t care to touch it barehanded either).
I put on some latex gloves and took it out of the cage, cut a small piece, maybe 1/4" square and put it in with the pheasent skin - it had bad problems. Put the rest back in the cage, and put the cage in a box with all my feathers.
Never saw another bug - no more damage.
It can happen fast.
I had a cape in a sealed ziplock baggy that was fine. I noticed some damaged feathers, and a week later it was dust and maggots, with what looked like miniature caddis flies in a swarm over the box.
No more problems - it has been months now.
And thanks for the welcome Bill, I have been reading for 2 years or so - just not much to say - much to read.
Take Care -
Jim
