防治方法：对介壳虫的防治应以预防为主。平时要经常注意察看株体，发现虫害，及早除治，以防蔓延。除治介壳虫可以人工、药物同时俱用。如只有1片2片叶梢发现虫害，可作人工刮除，用细木条削尖或用竹扦将虫体剔去。若出现大量若虫，可用25%亚胺硫磷乳没1000倍液喷杀，也可用40%的氧化乐果乳剂加1000-1500倍水制成溶液喷洒。一般喷洒1-2次即可将其杀灭。也可喷洒晶体敌百虫1500倍液。

防治方法是：要经常注意盆土表面有没有圆形土颗粒（即蚯蚓排泄物），若发现，可立即用50%的敌敌畏乳剂加1500-2000倍水制成溶液浇灌。浇灌后出现有蚯蚓钻动，立刻除去；隔一星期后再同样进行一次，即可将蚯蚓除尽。或用万灵浇灌，可杀死盆中的蚯蚓。
