Pest identification
What's eating my rattlesnake plant?
Spider mites
Signs: Pale stippling or bronzing on leaf surfaces; fine webbing under leaves; leaves curl and dry at edges
Control: Boost humidity; wipe leaves with a damp cloth; spray insecticidal soap or diluted neem oil every 5–7 days until mites are gone
Mealybugs
Signs: White cottony fluff tucked in leaf axils and around the base; sticky honeydew; leaves yellow
Control: Dab colonies with alcohol-soaked cotton swabs; spray the whole plant with neem oil or insecticidal soap; check neighbouring plants and isolate
Scale insects
Signs: Brown or cream-coloured bumps on leaf undersides and stems; yellowing foliage; leaf drop
Control: Scrape off with a soft toothbrush dipped in soapy water; follow with a neem oil treatment; repeat every 10 days for a month
Fungus gnats
Signs: Tiny flies near soil surface; root damage causes wilting and slow growth despite adequate watering
Control: Allow topsoil to dry between waterings; apply Bti (e.g., Gnat Nix or Mosquito Bits drench); use yellow sticky traps to monitor adults
