Orchids suffer the same as many other plants from pests. Here are a few of the more common ones which will harm your orchids.

Snails and slugs often hide in the potting media where they chew on young root tips; they also come out at night to chew on the leaves and stems. Some of the insect pests are Aphids (small sucking insects), and thrips (small chewing insects) which attack tender new growth, flowers and buds. Scale insects form a brown or black crust on leaves and stems. Mealybugs also attack the leaves and stems forming a white cottony mass.
