I. Common Areca Plant Problems
A. Pest Infestations
1. Identification Of Common Pests Areca Plant Problems
Spider mites are small arachnids that are difficult to see with the naked eye. They usually appear as tiny white or yellow specks on the leaves and can cause extensive damage to the foliage if not controlled.
Mealybugs are small, soft-bodied insects that are covered with a powdery white wax. They usually appear in clusters on the undersides of leaves, and they can cause wilting, yellowing, and distortion of the foliage.
Scale insects are small, oval-shaped insects that attach themselves to the stems and leaves of plants. They are usually brown or black and can cause leaf drop and stunted growth.
Red palm weevils are large beetles that can grow up to 5 cm in length. They bore into the trunks of palm trees, including Areca plants, and cause extensive damage to the foliage and stems.
