Scale Infestation

Question

I have some grapefruit trees and they have had scale for about a year and a half now. I’ve started using an insect soap and the scale have mostly disappeared, but there are still some left. I can’t get rid of them, what can I do?

Answer 1

Try using neem oil. It is organic and very effective against these pests. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
