White Scale on Crepe Myrtle: Systemic Imidacloprid Treatment

Crepe myrtles show tiny white oval scales on trunks and new leaf shoots.

Identification

Scale insects—many types. Crawlers settle permanently to feed.

Treatment

Bayer Advanced Garden Tree and Shrub Insect Control (imidacloprid)—blue bottle, soil application per label. Systemic, season-long. Dead scales don't fall off—monitor for new crawlers to gauge effectiveness.
