Naphthalene crystals

[fortbhoy]

i have got some wings that have been drying out for a while.
i bagged them and added a couple of crystals in each bag.
my question is how long do you leave the crystals in the bags?

You should always keep such materials with naphthalene, they help prevent moth attack. They don't help with materials already under attack, they are a preventive barrier.

Napthrlene is carcinogenic. Use a safe organic spray, of which google will find 100's. Or cedar chips, but they need replacing after every fow months.
