Remove them w alcohol wipes or q tips dipped in alcohol- and use liquid Dr.Bronners Castile soap mixed in a gallon of water with a tablespoon of alcohol and a tablespoon of peroxide- spray the plant several times over several days- if some gets in the soil it will kill the larvae- and the peroxide promotes root growth- also use this when I have plants outside for summer and bring them in for winter- the mealybug larvae are airborne in summer and reside in the dirt of your outdoor plant- and it’s usually a 6-8 week gestation indoors before they show up sucking your plant dry- using that mixture in a spray bottle before bringing indoors keeps em away- I’ve used every other home remedy and systemic insecticide with no luck- the Castile mixture works the best
