You're quite welcome. :) There's no such thing as overkill for me when it comes to those little buggers. I've found the zapper done with the other half of Dr. Clark's protocol works to get them all. But you really need to follow her directions. She was the zapper expert, eh?
I believe parazapper has one for around 100 bucks, if I remember one of his posts correctly, or making one yourself works too. I think she made it easy enough to understand for the average layperson to under stand.
