Q: I have a problem with scale. I have used a detergent and water mix and made sure every little bit got on the bulbs. However, I still have the problem. What can I do to get rid of these pests?


A: Scale insects are difficult to control. It takes a concerted effort on your part to bring their number down to a level that will not be harmful to the plant. If your attempt with the detergent and water did not work, then likely you are dealing with what are known as armored scale.
