Mealy Bug help needed

I usually use imidacloprid insecticide. You can spray it directly on the for quick kill, and also use it as a soil drench whereby the plant will uptake it and translocate it through its vascular system and then it kills the mealy bugs and other cytoplasmic “sucking” insects like aphids that return to the plant over a few months.

Most retail garden centers, good hardware stores, and likely even the 2 big box stores will carry an imidacloprid insecticide. Bayer manufactures one I’ve used in the past.

You can also use a all-season horticultural oil spray to smother them, also carried by retail garden centers.
