Any idea what these are? http://petersphotos.com/temp/Bugs.jpg Some of
my house plants (Buxus Sempervirens - Box Hedge) started getting waxy
and looking very ill a few months ago, so I sprayed them with Baby Bio
Insecticide twice. They are now healthily growing new leaves. But the
old leaves are still covered in these. Hopefully they're dead.

Scale insects and they probably are not dead unless you used a potent
systemic insecticide. Ignore organic (TM) growing advice and hit them
with a powerful systemic next spring when they are in active growth.

Something like Provado ought to see them off reliably

I used this, and the plant appears happy for the last few months.

A military pilot called for a priority landing because his single-engine jet fighter was running "a bit peaked."
Air Traffic Control told the fighter jock that he was number two, behind a B-52 that had one engine shut down.
"Ah," the fighter pilot remarked, "The dreaded seven-engine approach."
