Title: Message
The same fish/sesame oil stuff I mentioned for citrus scale
would work, but might be smelly for a greenhouse. It’s called
Organocide. For a small-scale problem, you could use a blend of pyrethrin
and insecticidal soap. You could mix that yourself, or buy Safer’s
Houseplant Insect Killer, which is fairly inexpensive. There is a
mealybug predator you could introduce, if you want Orion beetles patrolling the
sunroom. Or you could release the beasts outdoors, and let them control
the mealybugs during the warmer seasons, so by the time you bring in your
plants they would be pretty mealybug-free. This could be a long-term
solution, and is easy – but it’s the most costly – expect about
$80, more than 10 times the premixed Safer spray. I wonder why they’re spreading? Have you changed
soil mixtures? Are the plants otherwise happy and healthy? I would lean toward the pyrethrin/soap mix, and see what you can
do outdoors to attract predatory insects; also check the soil in your pots for
mineral build-up or nutrient presence and availability. Maybe some things
want repotting, with some slow-release organic fertilizer added. ~ Stephen From:

Behalf Of Brungardt, Sam Every
year about this time I find mealy bugs have infested some of the plants that I
overwinter in our sunroom. Often these are plants on which I've never
seen these pesky critters before. Right now I have some on rosemary,
amaryllis and stephanotis. I have always been fearful that the mealy bugs
will infest more of my plants and my standard weapon was banishing
the plant to the outdoors (which with our below-zero temps at this time of the
year does a satisfying job on the bugs but I lose the plant as well). This
year I'm trying to control the mealy bugs with rubbing alcohol on a
Q-tip. I swab every above-ground portion of the plant with alcohol,
but control is temporary at best. I sure would appreciate some ideas for
dealing with mealy bugs. I really hate to keep throwing away plants, but
that might be my only alternative. Thanks in advance for your advice. --
