Step 4: In June one of the most prominent pests is the bagworm.

Bagworms prefer Arborvitae’s, Junipers, Cedars and occasionally white pines. The damage to these evergreens can be severe. Upon hatching the larvae enclose themselves in silken bags which are constructed from plant parts and can reach 2" in length. A small population can be hand picked from its host. However, in heavy infestations a pesticide is recommended to ensure the health of the plant. Each bag contains up to 1,000 eggs. Pesticide applications are ineffective unless they are made before August.
