Re: Alternative to Mothballs ???
Can't you keep all of the materials in the containers with the mothballs except the material you are tying with?
This has worked for me for a long time including the past 10 years of living in the south where bugs have a LONG season to find stuff to eat. Truth-be-told, I also keep them in sealed zip lock bags inside of the containers. Better safe than sorry as the old saying goes.
