Hoyas and Insect Pests

Hoyas can be susceptible to a variety of insect pests, including:

• Mealybugs
• Spider mites
• Flat mites
• Root mealies
• Thrips, and
• Aphids

These pests can damage the leaves, flowers, and stems of the plant, and may even cause it to decline or die if left untreated.

Hoyas, similar to to other indoor plants can be attacked by pests dues to a number of reasons. First, they are popular tropical houseplants that are often grown indoors or in greenhouses, where the relatively warm, humid conditions can be conducive to insect infestations. Additionally, hoyas have relatively thin, succulent leaves and stems, which can be attractive to sap-sucking insects.

Furthermore, hoyas are often grown in soil or soilless mix that can harbor insect eggs, larvae, and pupae, which can then hatch and infest the plant. Pests can also be introduced to the plant through infested plant material or from other plants in the same collection.

Finally, if a hoya plant is stressed or unhealthy due to factors like inadequate light, improper watering, or poor nutrition, it may be more susceptible to insect infestations. Insects can sense weak or damaged plants and may be more likely to target them.

To prevent insect infestations in hoyas and other plants, it's important to practice good cultural care, including proper watering, fertilization, and sanitation. Regular inspection of the plant for signs of pests can also help catch infestations early and prevent them from spreading to other plants in your collection. If an infestation does occur, there are a variety of treatment options available, including physical removal of insects, insecticidal soaps or oils, and systemic insecticides.
