Scales suck out the nutrients from your orchid and can be found in the leaves, petals, sepals, petioles, and pseudobulbs of your plant.

If the scales infestation is a bit minimal, you can easily handpick them out of your plants. Rubbing alcohol, insecticidal soap, and oil spraying are effective ways to manage the infestation of scales on your orchid plant.

2. Mealybugs

Mealybugs, just like scales, are serious orchid pests. They are also quite challenging to control. They can be found on your orchid roots, pseudobulbs, and the underside of leaves.

They can also burrow in the rhizomes and potting media of your plant. The use of rubbing alcohol and repotting is also suitable for controlling these orchid pests.

Some horticultural oils and soaps are also good for keeping orchid pests.

3. Aphids

Aphids are also similar and related to scales. They are soft-bodied insects commonly found in orchids. Aphids are mostly found in new growth, at the base of flower buds, and on the undersides of leaves.

You can control aphids by blasting them away with a garden hose or handpicking them out if the aphid infestation is a bit minimal. Organic garlic and chili sprays are also proven ways to eradicate aphids.
