Planttalk Colorado provides the following steps to control Mealy bugs. Prune infested branches and remove and destroy heavily infested plants. These pests may also be controlled with insecticidal soap. For heavy infestations, spray a mixture of 10 percent rubbing alcohol and 90 percent water directly onto the insects. For smaller infestations, dab the insects with a cotton swab dipped in rubbing alcohol. Repeat this procedure every week until the bugs are gone. Make sure to test the soap and alcohol mixtures on a small portion of the plant prior to full application because some plants may be sensitive to soap or alcohol.
