Answer: I'm not sure what the gooey spots are. Could be scale insects or mealybugs - both are common on houseplants. Try dabbing each spot with a Q Tip dipped in rubbing alcohol. That should kill off individual insects. In a few days you should be able to peel them off with your fingernail. A large population of these pests can eventually kill your plants so get them under control as soon as you can. Best wishes with your plants.
