Thank you BM & Jim for your info.  May I substitute traditional mothballs (para-dichlorobenzene (1,4-dichlorobenzene) variety) for the Para-Moth brand?  It seems difficult to get the name brand stuff shipped to Hawaii, but I can acquire mothballs locally, which seems to be the same chemically (newer mothballs at least...older ones were a more flammable chemical, however the new version seems to be para-dichlorobenzene (1,4-dichlorobenzene) all-around unless I'm mistaken.  Thoughts?

I put paradichlorobenzene mothballs in with frames to help keep pests away over winter, and I've never had any issues.

But the mothballs are deadly to the bees!

As long as its para-dichlorobenzene or PBD its ok. Maybe some places it comes in different forms/names than we are used to seeing. It just has to be para-dichlorobenzene or PBD. I guess to put it another way it could be called scoot moth and be shaped like a glass as long as the ingredient label reads para-dichlorobenzene its ok.

DITTO!  Check your active ingredient labels, whether it's crystals or balls.  Paradichlorobenzene is what you want.  Naphthalene, the other common active ingredient in these types of products, is NOT safe for use with bees in any capacity.

But the mothballs are deadly to the bees!

Paradichlorobenzene can kill bees if they are exposed to the mothballs themselves.  So don't put paradichlorobenzene in a hive with live bees or anywhere else bees could get into them, only in empty stored equipment/wax, and the equipment should be aired out before use like Jim said.  The difference is the paradichlorobenzene won't leave any dangerous residue behind, but the naphthalene will.

There is always residue left behind but in very tiny amounts.  The problem is taking it on as a practice means repeat doses.  There is noting harmful in drinking water from a plastic bottle until all your food is packaged in plastic.  So you go from one drink in a plastic bottle to consuming everything package in plastic.  There never is that amount of testing done on consumables except time.

Thank you all for the informative and insightful responses.  I will be sure to procure para-dichlorobenzene crystals.  (Indeed, the traditional Moth Balls still seem to be made of Napthalene, however most Moth Crystals and Moth Cakes I've found listed list para-dichlorobenzene as the active ingredient.)  Looking around at local stores online some carry it, so there's hope for me sourcing it here.  Thanks everyone for your direction.
