Because America Shirohitori grow as a group in the nest net, which is on the back of the leaves, until they reach their final form as worms, they are removed directly by cutting off the affected branches and leaves before they grow up to be imagoes, or are exterminated by spraying an appropriate amount of insecticide such as fenitrothion or emulsion of acephate.
アメリカシロヒトリは、葉の裏に造る巣網の中で3齢虫まで集団で成長することから、成虫になる前に枝・葉を落とす直接除去もしくはフェニトロチオンやオルトラン乳剤などの殺虫剤を適宜散布することにより駆虫する。
