What's eating my dracaena deremensis janet craig?

Spider mites are the biggest threat to Janet Craig indoors, especially in dry air. Mealybugs and scale insects also attack, hiding in leaf axils. Thrips occasionally cause silvery streaking on the long, glossy leaves. Regular inspection and wiping leaves down keeps most infestations from taking hold.

Fine webbing on leaf undersides; leaves develop a yellow, stippled or bronzed appearance and may drop prematurely. Raise humidity, mist regularly, and wipe leaves with a damp cloth. Treat heavy infestations with insecticidal soap or neem oil, repeating every 5–7 days.

White cottony clusters in leaf axils and along midribs; sticky honeydew leads to sooty mold and leaf yellowing. Dab individual bugs with a cotton swab dipped in 70% isopropyl alcohol. For larger infestations spray with insecticidal soap or diluted neem oil.

Brown or tan dome-shaped bumps on stems and leaf midribs; affected areas yellow and growth weakens. Scrape off visible scale with a soft toothbrush, then treat with horticultural oil or neem oil. Repeat after 2 weeks to catch crawlers.

Silvery-white streaks or flecking on leaf surfaces; tips may turn brown and leaves curl slightly. Isolate the plant and spray all surfaces with insecticidal soap or spinosad-based product. Remove severely damaged leaves and repeat weekly for 3 weeks.
