Green lacewing for brown soft scale

Chrysoperla carnea · green lacewing larvae
Against brown soft scale

UC lists lacewings among the predators of scale insects, and the crawler is the mobile first-instar stage. Brown soft scale breeds all year indoors, so crawlers keep appearing — but no release trial of lacewings against this scale was found, and settled adults are unlikely prey. Check for moving crawlers with a lens before ordering, and treat this as a supplement rather than the main control.

RateNot recommended — no release trial against soft scale
TimingWhile crawlers are moving, not when only settled adults are present
Temperature20–28 °C best; works above a 12 °C average
