Signs of scale insects and mealybugs include sticky leaves and black, sooty mold. Use your hands to remove all the visible insects on the top and underside of the leaves and flower stalks. After removing the insects by hand, add a squirt of dish soap to a cup or bowl and add room-temperature water. Dip a soft cloth in the solution, then gently wipe down each leaf and flower stalk. The soapy water will remove the stickiness and soot as well as kill any remaining insects. If you removed the bugs and cleaned the leaves but are still seeing signs of an infestation, pick up an insecticide at your local garden center. Ask an employee to help you find an insecticide that is safe to use on orchids. Follow the application instructions on the package. If you notice that your orchid has discolored leaves or spots on it (like cream, yellow, brown, or black), it is likely suffering from a disease. The first step is to remove as much of the infected tissue as possible. Use a sterile cutting tool to cut away diseased leaves, stems, and flowers. Be sure to disinfect your gardening tools before and after removing infected tissue. In some cases, it may be best to dispose of the entire plant to keep the disease from spreading. Common bacterial infections that may affect orchids include brown rot, black rot, and brown spot, indicated by dark spots on the leaves or pseudobulbs. Common fungal infections include blight and root rot, indicated by rotting roots, pseudobulbs, and leaves. After cutting away the infected tissue, spray the orchid with a fungicide or bactericide, depending on what it is suffering from. You can find these products at your local gardening center.
