I use 1 tsp oil (vegetable or mineral)
1 tsp vinegar
1 tsp soap (must be SOAP bar ivory is about the only brand name left
that is soap and NOT the liquid dish stuff they changed that to detergent.
1 qt water
The vinegar dissolves the cotton from mealy bugs, oil suffocates the buggers,
and the soap is gentle and breaks the oil down to microbeads to be more
effectively administered. This works on ferns with no damage and since I
have frogs and fish in the conservatory I worry about toxicity of things like
pyrethrins, they are toxic to critters.
