Mealy bugs derive their name from the white, waxy, mealy secretions that cover their bodies. Several pest species attack both indoor and outdoor plants. The taxus mealy bug is unusual in that it has only one generation per year. Other mealy bugs have several generations and can build up rapidly. Nymphs and adults cluster together at favorable feeding sites. White, waxy filaments may cover entire colonies. A forceful insecticide spray containing a wetting agent is necessary for effective control.
