You don't have to go to India to get Neem oil; Gardens Alive sells it as
Neem-away. We've used it for the aphids on our roses and some leaf-eating
pests in the garden. I heard a rumor it was being tested for use in hives
for both mites, but haven't heard anything yet of its efficacy. Gardens
Alive can be contacted at 812 537-8650.
