The Hoya plant, also known as the wax plant, is a common house plant that is native to Florida. It has distinctive waxy leaves that grow from woody vines. While easy to care for, Hoya sometimes suffers from insect infestations.
Insects like mealybugs, aphids, scale bugs and thrips can sometimes infest your Hoya plant. While each bug will cause different symptoms in your Hoya plant, most can be eliminated with an insecticide.
The bright yellow Oleander aphid is the most common aphid to feed on the Hoya plant, according to the University of Florida. Aphids excrete a sticky substance known as honeydew that can stunt plant growth. Bugs like thrips feed only on leaves and will cause leaf distortion and curling.
If infestations of insects like mealybugs or scale bugs get too severe, their excretions can be very damaging to your Hoya plant.
