Answer: The ladybugs are there to control the other insects on your oleander so just let them do what they do best - feed on destructive insect pests. Eventually a natural balance will be reached and the ladybugs will leave. At that time you can prune your oleander back to encourage healthy new growth. In the meantime just water your oleander deeply twice a week during the hottest weather and once a week the rest of the year.
