>I had understood that Moth Balls are of no use with wax moth..but after reading the above, I am confused. Clarification please?..:) Possibly the confusion is related to there being different types of "moth balls". What I find most commonly sold as moth balls is naphthalene. This is a moderately good insect repellent, horse---- as an insecticide, and would not control established insects. Paradichlorobenzene/PDB is most commonly sold around here as crystals, although "balls" are also sometimes available. It is a fairly effective fumigant insecticide used for control of many insects. I think it also has some repellent activity. Whitney Cranshaw [log in to unmask] Colorado, USA
