I had a problem with scale and this is what I used along with adding alcohol to break down their hard bodies Not necessary for spider mites
In the juvenile or crawler stage, scales are translucent and take on the color of the leaf or stem surface. As they mature, scales develop a hard, dark brown shell that is more visible (the shell protects the scale babies underneath). The Scale bug comes in different colors such as brown, white, and black. And like the mealy bug, the scale bug also secretes honeydew on the leaf which resembles the stickiness of soda pop. Death of infested plants is possible in severe cases, but usually scale insects just feed by sucking plant sap and causing poor, stunted growth. If you see the honeydew, look for the pest.For control of scale, spray with insecticidal soap, oil soap, or rubbing alcohol with a small amount of dish soap mixed in. Another good method of controlling scale is to wipe, pick, or scrub off the insect. Persistence is extremely important here. These scales are easily scraped off the plant tissue with a fingernail. If these remedies don’t seem to work you should as an alternative, try spraying with rubbing alcohol; that will help break through the outer barrier of the scale and kill it. Mix 1 part alcohol with 8 to 10 parts of water. The main problem you may come across is that the young scale or crawlers are nearly clear and are very hard to locate, so you may want to spray the entire plant surface until it drips, just to make sure you’ve covered all the cracks and crevices. After about five to seven days, it’s best to repeat this treatment to catch any crawlers that you may have missed the first time around. After this is done, you should continue to check your plant once a week to make sure these unwanted guests haven’t returned.
