What's eating my sansevieria laurentii?

Sansevieria Laurentii (now Dracaena trifasciata 'Laurentii') is a tough, low-maintenance houseplant but is susceptible to spider mites in dry air and mealybugs hiding in the tight leaf sheaths near the base. Scale insects can encrust the succulent leaves. Fungus gnats are common when the plant is overwatered. Overall pest pressure is low with correct care.

White cottony masses deep between leaves at the base; honeydew drip and leaf yellowing; easy to miss until population is large Remove by dabbing with isopropyl alcohol; spread leaves to treat hidden colonies; apply neem oil drench and repeat after 2 weeks; use systemic insecticide for severe cases

Faint stippling and subtle webbing on leaf surfaces, most common in heated rooms with very dry air Increase humidity; wipe leaves with a damp cloth; apply insecticidal soap or neem oil spray, repeating weekly for 3 weeks

Brown or tan waxy bumps adhering to the leaf surfaces; yellowing and weakened growth; sooty mould on honeydew Scrape off with a soft toothbrush or cloth dipped in soapy water; treat with neem oil or a systemic insecticide; inspect monthly as they spread slowly

Larvae in wet compost damage shallow roots; adults fly up when soil is disturbed Allow soil to dry almost completely between waterings — the most effective control for this drought-tolerant plant; use yellow sticky traps and Bti drench if needed
