Pest identification
What's eating my sansevieria trifasciata black gold?
Mealybugs
Signs: White cottony masses deep between tightly bunched leaves; honeydew deposits and yellowing; infestations grow large before they become visible
Control: Separate leaves and apply isopropyl alcohol directly to colonies; follow with a neem oil spray over the entire plant; repeat after 2 weeks; use imidacloprid drench for heavy infestations
Spider mites
Signs: Faint stippling and webbing on leaf surfaces, especially during winter when heating systems reduce indoor humidity
Control: Wipe down leaves; boost humidity with a nearby water tray; spray with insecticidal soap or neem oil every 7 days until clear
Scale insects
Signs: Hard waxy brown bumps on leaves and at the base; slow yellowing and reduced vigour; sooty mould on honeydew
Control: Remove physically with a damp cloth or toothbrush; treat with neem oil or systemic insecticide; inspect monthly as scale spreads slowly between plants
Fungus gnats
Signs: Root damage from larvae in wet compost; adults hover around the soil surface when the plant is disturbed
Control: Allow soil to dry almost completely between waterings — this plant tolerates drought; use yellow sticky traps and apply Bti drench to kill larvae
