I hope this isn't the archives! It has been reported that grapefruit
leaves are also an effective mite drop tool. Sorry for the hearsay but, I
can't remember the source of this report.

I have a hard time not responding to messages even though I have no source.
Must you have the source to throw new information in the discussion? Isn't
it a mistake to discount new information just because the informer doesn't
have a study to back it up? Won't it make people with valuable information
hesitant to share it if they're afraid someone is going to publicly ridicule
it. And finally, what if a subject has been covered in the archives, does
that mean you can't get new information from new beekeepers who weren't on
the BEE-L when the subject was discussed the first time around?
