My hibiscus has white dots which I am assuming are bugs. I also notice a lot of flies hanging around. I have sprayed with Sevin without success. Need advice.

If the white dots fly away when you get near them, they are whiteflies. Insecticidal soaps work well against white flies. Just be sure to spray both top and undersides of leaves. Insecticidal soaps can cause burning of leaves if applied during hot weather, so use caution. Good luck in getting rid of those pesky pests!

If the white dots do not move, they can be cottony scale insects or mealybugs. These insects feed on the fluids within the tissues of your plants and while doing so exude a sticky substance called honeydew. The sugary content of this substance can attract flies. Insecticidal soaps can sometimes kill these pests, as well. Be sure to apply according to label directions.
