This is just an FYI. Paramoth, para-dichlorobenzine, can be bought at your local Wal-Mart for substantially less than is offered at the bee supply stores. Wal-Mart sells the Enoz brand for $4.36/lb., which is exactly the same brand and packaging that Betterbee sells for over $11. It treats 50 cubic feet or around 45+ medium supers. It is marketed as Moth Ice Crystals and is found in the laundry section near housewares. Make sure the bag says p-dichlorobenzine in the active ingredients and not napthalene.
