You can also buy pure cedar oil, for renewing cedar. It is good for your hands, I also used for fleas on my cat. No fleas, or eggs now. Just use a few drops in your hands, and rub your hands together, and then rub against the grain of the hair, and around the neck, and top of the head, and stomach, and tail. They don't like it, but in a few minutes, the smell isn't quite so strong. But the fleas are dead, or getting out of Dodge! Try that, and see how it works. Just make sure it is pure cedar oil. You don't want to put to much on your cat, or dog, just a few drops, if that, on your hands, and rub them together, and wipe it on your dog, or cat. It doesn't take much. Try a little on a rag, or your hands, and rub the feathers and see how that works. Roaches,and moths love feathers. But cedar oil will kill them! Anywho try it and see if that solves your problem.
