First we cut mainly affected young shoots and the plant altogether somewhat trimmed. Then the Ficus 2x was thoroughly sprayed at intervals of several days with Calypso Perfect AF, including the undersides of leaves.
Because the lice after 10 days still perk were crawling and had now set even "young" we had a third treatment with Calypso perform.
Result about 3 1/2 weeks of treatment: zero effect - the lice feel magnificently well and multiply diligently.
It may be that the funds might in some pest types works well, but definitely at mealybugs not. Therefore, I no recommendation!
