Aphids are sucking insects that are some of the most problematic orchid pests. One of the signs of aphid infestation is a collection of tan-colored skins on the plant. Leaves will also become covered in honeydew and bud and flowers will become stunted or deformed. You can simply brush them away or spray them off with water.

Fungus Gnats

Fungus gnats are also shared orchid pests. Their larvae grow in potting media that is too wet, warm, or decaying too quickly. To control these pests, make sure you don’t keep the potting media too wet and allow it to dry between waterings. You can also use the yellow sticky cards that are commonly used to control white flies.


Some of the other types of orchid pests are mealybugs. They satisfy under bracts and on the roots. They copy throughout the year under greenhouse conditions. They cause the leaves to turn yellow and drop early. harsh infestations of mealybugs will weaken the plants and may already kill them.


Mites are also orchid pests. These microscopic animals kills the cells of the surface inner of the leaves. This causes the leaves to look silvery, especially on the bottom. There may also be yellow spots on the top of the leaves. Mites can severely weaken and disfigure plants. To combat mites, you should wash the plant thoroughly and wipe every leaf.

Some of the last shared orchid pests are white flies. Like aphids, they are sucking insects but much smaller. An infestation of white flies can severely weaken your plant. They are extremely difficult to control under greenhouse conditions. The only way to control them effectively is to use insecticides.
