I thought mothballs were either para-dichlorobenzene, naphthalene or camphor. Para-dichlorobenzene is considered a potential carcinogen in California. Why only in California - who knows?

Yes Para-dichlorobenzene is usually *mothballs* but in a metal container with small holes in it?? This stuff gets rid of mites and flies??? in a worm culture without killing the worms? Is there a brand name for this Bird Protector?
