How to control Japanese wax scales?
Handpicking scales in winter (if practical) is an effective control measure. Since they may lay their eggs apart from their host plants, the scales should be destroyed after removal. The Japanese wax scale seems to be one of the most difficult ornamental plant pests to control. However because there is only one generation per year, applying pesticides to the crawler stage in early June will give virtually complete control. Applications of any pesticide must be repeated because the crawlers emerge from the female's protective wax coating for 2 or 3 weeks and because recommended pesticides grow ineffective in the environment. For specific controls, see the current state extension recommendations.
