LOL, Kell! Yah. I'm not really sure whether that is accurate about not letting in new insects, even beneficial ones. I really haven't done enough research on the matter to be able to discuss it intelligently. My inclination is that the infestations of six-spotted, two-spotted, and broad mites are so bad that biological controls are only effective on minor occurrences and not severe occurrences, but I'm not sure of how many studies have been done and what conclusions were drawn here in the states.
