What's eating my thomsonii wax plant?

Hoya thomsonii, like most hoyas grown indoors, faces its greatest threat from mealybugs hiding in stem joints and leaf axils. Spider mites can establish quickly in dry indoor air. Regular inspection, good humidity, and early intervention with isopropyl alcohol or neem oil are the primary defenses for this species.

White cottony wax in stem crevices; honeydew and sooty mold on leaf surfaces; weakened growth Swab with 70% isopropyl alcohol; spray entire plant with insecticidal soap; repeat every 7 days for 3 weeks; keep isolated

Fine bronze or silver stippling on leaves; webbing on undersides in heavy infestations Raise humidity around the plant; rinse foliage; apply neem oil or miticide spray weekly until resolved

Larvae chew fine roots; adults are a nuisance around soil; seedlings and cuttings most at risk Allow soil to dry well between waterings; use yellow sticky traps; drench soil with diluted neem or Bacillus thuringiensis israelensis (Bti)
