I'll confirm that it kills mites.
As will almost any oil. (suffocates them).
Rosemary has the advantage of strong scent.
That scent acts as a repellent for most "flyers too.

Used it once, a while back.
It worked.

Will not use it again, at least not on buds.
For the same reason I won't use Neem

The strong odor/taste of Rosemary tainted the buds and is persistent.
Call me picky, but that's just unacceptable.

Good recipe though,
Thanks benaynay.
Quite useful for folks that like the taste.

Aloha,
Weeze
