What's eating my never never plant 'grey star'?

Never Never Plant 'Grey Star' is most susceptible to spider mites, which flourish when indoor air is hot and dry. Mealybugs nestle in the leaf sheath joints. Fungus gnats exploit waterlogged soil. Keep humidity high, water only when the top inch of soil is dry, and inspect weekly.

Pale stippling on the silvery-grey upper leaf surface; fine webbing on undersides; leaves curl and brown at edges Mist leaves and wipe undersides; apply insecticidal soap or neem oil spray every 7 days; move away from radiators

White woolly deposits at leaf sheath bases and in stem forks; weakened stems; honeydew residue Dab with 70% isopropyl alcohol; follow with a neem oil foliar spray; isolate plant from other calatheas and marantaceae

Larvae chew fine roots causing yellowing and wilting; adult gnats hover around the pot Let soil surface dry between waterings; apply Bti (Bacillus thuringiensis israelensis) drench; use yellow sticky traps
