If you're dealing with mealybugs, there are a couple of methods you can try to get rid of them. One option is to bring in natural predators like ladybugs or green lacewing larvae. Another option is to make your own insecticide by mixing 1 teaspoon of liquid soap with 1 liter of water. Apply the solution to the affected areas and make sure to rinse everything thoroughly. Be careful not to leave any water on your plant's foliage.
