OK....now when someone says "heave it", I have to make a suggestion.  I
have several hundred orchids that have always been pest free from day
one.  Until this year.  I purchased some cattleyas that came with guests
unbeknownst to me.  The orchids sit on shelves for a couple years at a
time, and when I finally found the scale, it looked like white mold.
You couldn't even see the leaf surface.  I mixed Isotox up in a bucket,
donned rubber gloves, and after scraping off what scale I could, I held
the pot upside down and plunged it completely under the insecticide.  So
far, so good.  No recurrance.
Secondly, check the variety of cacti you have.  Some have a natural
encrustation found on the ridgelines of the plant.  This is not always
found on immature plants.  Maybe you'll get lucky.
