Combs Smelling of PDB Jar Fumigation Method Wax Moth Treatment		"A-Z" INDEX &   SEARCH PDB Crystals Para Dichloro Benzene used in Wax Moth Control

Chemical Name... Paradichlorobenzene Molecular Formula... C6 H4 Cl2 Molecular Weight... 147.00 Other Names... PDCB, P - Dichlorobenzene

If supers must be stored in a warm room or cellar or stored during the Summer and Autumn months, they can be protected by using Paradichlorobenzene (PDB) crystals. These crystals are placed on a small piece of paper between every fourth or fifth super in a stack, which should then be sealed using parcel tape.

The treatment must be repeated by replenishing the crystals at regular intervals as PDB kills adults and immature wax moths, but not eggs.

The presence of crystals within the stack repels any visiting moths and inhibits egg laying, and also kills young larvae that may hatch after the combs are placed in storage.

Supers should be aired before using them on colonies. See label or package for details on using PDB.

There is a variation of this treatment whereby newspaper is spread over every super and a few crystals of PDB sprinkled on each layer. A further variation is to place the crystals in a stationary envelope and pin the open envelope inside a super using a drawing pin (thumb tack) through the flap.

Moth balls and some crystals are made from naphthalene, which is not the same as Paradichlorobenzene (PDB) crystals and is not recommended for wax moth control.
