Yes, Aphids, Cyclamen Mites, Red Spiders, Mealy Bugs, or Botrytis Blight can attack African violets.
Insecticidal soap sprays can control most insects and mites.
Mealybugs may be controlled by mixing rubbing alcohol with an equal amount of water and touching each insect with a cotton swab dipped in the solution.
Cyclamen mites are one of the most serious pests of African Violets. They are very small and cannot be seen with the naked eye. They may cause severe stunting of leaves in the center of the plant, sometimes with leaf curling. New leaves are often very hairy, making them appear grayish. Flower buds may also be stunted and misshapen or even fail to open. Badly infested plants should be discarded. Kelthane sprays may be used if many plants are affected.
