Unless you turn the composter often enough and have the proper ingredients, it won't get hot enough to kill insect pests. I would recommend removing the stems with mealybugs on them. In the future, watch for any infested plant material and throw it in the trash rather than the composter. A few bugs that don't harm plants are OK, but mealybugs are sapsuckers that will harm plants if they survive the compost bin and are applied beneath plants.
