Hi. Im having a small problem with Mealys, and not having much luck with

Knox-out works well is not too toxic. It is micro-encapsulated diazanon, water
based, no solvents and will not damage buds or flowers. Depending on where you
live you could take the plants outside, spray them and when dry take them back
inside. If you can't do that you can always make up the solution in a large
bucket and submerge the plant.

We had about a hundred maudies infested with mealy and the only thing that
worked was submerging the plants in the Knox-out solution.

Mealy bugs are usually a problem when the humidity is too low or the plants are
not watered on a frequent enough basis, same for scale.

BTW: This insecticide can only usually be purchased from a nursery/greenhouse
supply company not your local garden center.
